Braintree to Cohasset, ITS miles of double track. (5.) Nantasket Junction to Pemberton, 6'9 miles of double track. (6.) Providence to Fall River, 18 miles, of which 10 miles are double track. The first of these to be equipped electrically was the line from Nantasket to Pemberton, in 1895. The New York, New Haven, and Hartford Railroad found at that time that the trolley lines were seriously affecting their revenues, and in order to meet this competition they decided to equip some of their branches electrically. The result of doing this to branch No. 5 was so satisfactory that the process was extended to the other branches, some of which had up to that time been worked at a loss. The following table, compiled from the most recent available returns, was given to me, and shows the increase of annual passenger traffic due to the change : Branch. Steam. Electricity. 1 Passengers. 98,300 Passengers. 184,728 2 367,695 1,060,617 3 267,936 341,207 4 and 5 304,292 702,419 This large increase in traffic may be attributed to the greater frequency ol the service, the reduction of fares, and the increase in speed. 15 Branches 2, 3, and 4 are equipped with the third rail ; the others have the overhead trolley. The trains consist of two to five cars, and are run at a schedule speed of 30 miles per hour, with an average of one stop per two miles, the maximum speed being 45 miles per hour. The weight of a motor car is 45 tons, and its seating capacity is 60 passengers. On the Providence and Fall River Line the trains consist of one, two, or three cars, there being 112 of such trains daily. The service is both local and express, the running time of the local trains with 26 stops being 45 minutes, which is equal to a schedule speed of 25 miles an hour. The express trains with seven stops cover the distance in 33 minutes, which is equal to a schedule speed of 32'7 miles an hour. The old steam schedule between Providence and Fall River was 48 minutes for local trains with 14 stops, and only 10 trains per day, and there was no express service. The rolling stock of this branch consists of 46 cars, of which 24 are passenger coaches used as trailers, and nine are combination baggage and passenger cars, the remainder being motor cars. The cars are 40 ft. in length over all. The motor cars have four 80 H.P. motors, and weigh 30 tons. The wheels on the motor cars are 36 ins. in diameter, having a l^-in. flange and a 3 -in. tread. The rail used weighs 78 Ibs. per yard, and the road bed has gravel ballast. The population of Providence is 175,000, and that of Fall River 104,000, and the average daily traffic is 15,000 passengers, the fare for the whole distance being 20 cents, which is half the whole steam fare. The above description affords a good idea of the results obtained by the operation of unremunerative branch lines of main railroads by electricity. Of High Speed Inter-urban railways specially built for operation by electricity, I visited four, viz. : (1.) The Schenectady and Albany Railway. (2.) The Buffalo and Lockport Electric Railway. (3.) The Detroit and Port Huron Shore Railway. (4.) The Aurora, Elgin, and Chicago Electric Railway. (1) The Schenectady- Albany line is a high speed overhead trolley railway, 17 miles in length, between Schenectady and Albany, 4J miles of which are Avithin the limits of the two cities. It is a double track located on the public high- way, the district between the termini being rather sparsely populated. The population of Albany is 100,000, and that of Schenectady 50,000. The average schedule speed is, for the whole journey, 18 miles per hour, with nine inter- urban stops and about 22 city stops. The schedule speed between the cities is 27 miles per hour, and the maximum speed is 50 miles per hour. As a rule single cars are used, weighing 24 tons each, and with a length over all of 48 ft. They are equipped with four 50-H.P. motors, and have a seating capacity of 52. The motor truck wheels are 33 ins. in diameter, with ^-in. flange and 2|-in. tread, the axle being 4i ins. in diameter. The transmission current is three-phase-alternating at 11,000 volts, the greatest distance to which it is transmitted being 17 miles. The working current is 550 volts direct. There is a 15-minute service between the two places during the day and evening, and an hourly service during the night. The number of passengers carried is about 3,700 daily, .the single fare being 25 cents (Is.), and the double fare 40 cents. The Xew York Central has a steam railway alongside of the electric line, the passenger traffic on which has been greatly reduced since the latter was opened. The fare on the steam railway is 39 cents single ticket. It takes about 55 minutes on the electric railway to travel from the centre of Albany to the centre of Schenectady, and 40 minutes on the steam railway, but the smaller fare and the frequency of the service render the former the more popular route. 16 There is an " express," i.e., baggage and parcel, service, and a freight service on the electric road, separate cars for the purpose running every hour, the gross tonnage carried averaging 1,043 tons per month. The tracks are laid with 80-lb. T-rails on cross ties, and are well ballasted . They occupy about two-thirds of the width of the public highway, and though the Company' possesses no exclusive right to any portion of the highway, the mode of construction of the railway, and the elevation of the rails above the road practically deprive the public of the use of so much of the roadway as is required for the railway. Probably no great inconvenience is experienced on this account, as the highway is unmetalled, and is little used for vehicular traffic. The advantages conferred on the public by the railway more than balance any inconvenience due to its presence. (2.) The Buffalo and Lockport Electric Railway is an overhead high speed single track trolley line 25i- miles in length, of which 12i miles are within city limits. The motor cars are 42 ft. long over all, and are fitted with four 50-H.P. motors. There are also some 30-ton electric locomotives used for freight service, \vhich haul ordinary freight cars, and which are equipped with four 1GU-H.P. motors. The schedule speed for inter-urban running is 27 miles an hour, and the maximum is 50 miles an hour. The round trip fare from Buffalo to Lockport and back is 75 cents (3s.). The line is operated by the International Traction Company of Buffalo, which also owns the electric railway between Buffalo and Niagara, etc. The current is derived from the Niagara Falls Power Company. (3.) The Detroit and Port Huron Shore railway is a single track road with passing loops, having a total mileage, including lines within city limits and passing loops, of 110 miles. It is a trolley line laid, so far as I saw it, along- side the highway, and endeavours have here been made to interfere as little as possible with the use of the highway for its original purpose. The power station is at New Baltimore, about 32 miles from Detroit, and the current is transmitted to a distance of 40 miles in one direction and 20 miles in another. The transmission current is 16,000 volts, and there are live sub-stations equipped with 200 K.W. converters from which the trolley current is supplied. Most of the cars are geared for a maximum speed of 45 miles an hour, some with two motor equipments and some with four. The freight cars have four motors. Fifty passenger cars and 25 freight cars are in service. Detroit is now the centre of about 400 miles of inter-urban railway, and much valuable experience has been gained here in the operation of this class of line. As the various lines were originally the property of different companies a great variety of construction is to be found. Nearly all the lines are now under the control of the Detroit United Railway Company, who are engaged in establishing a uniform system of equipment and operation. (4.) The Aurora, Elgin, and Chicago Railway is one of the most recent and most important undertakings of this class yet constructed. The total length of route is about 60 miles, the greater portion of which is double track. The line is built entirely upon the company's own land except at public road crossings, the width of land occupied being from 100 to 60 ft. It is laid throughout Avith 80-lb. steel rails in 60-i't. lengths, with 2640 ties to the mile. It is operated on the third rail system, the conductor rail weighing 100 Ibs. per yard, and being of a special description of soft steel. The top of this third rail is 6y\ ins. above the top of the running rails, and it is placed 19 ins. outside the track. The track is most substantially constructed so as to be suitable for very high speeds, the regular maximum speed being intended to be 65 miles an hour, while 80 to 100 miles an hour can, it is anticipated, be made with safety. Experiments with such speeds are to be made next spring, after the road bed has had time to become thoroughly consolidated. The power house is at Batavia at one end of the line, and there are six sub-stations. The transmission current is 26,000 volts 3-phase alternating, and is carried by aluminium stranded cables, on polos placed alongside the tracks, the same poles 17 also carrying the telephone wires. The traction current is 600 volts direct, and no direct current feeders are needed, as the third rail has sufficient carrying capacity to conduct all the current needed from the sub-stations to the trains in the different sections of the line. The trains consist of one, two, or three cars. The one and two car trains have every axle motor-driven ; the three car trains have one car without motors. The cars are 47 ft. over all. Those carrying motors are of extra strength in the sub-frame, and have four 125- H. P. motors, the most powerful equipment ever put on a motor car, other than those used on elevated railways, where the motor cars act as locomotives to haul several trailers. The wheels are 3G ins. in diameter, and have Master Car Builders standard flanges and treads. The axles are 6i ins. in diameter, being the largest yet used on an electric car. The trains are expected to attain a speed of 50 miles an hour in 25 seconds starting from rest, a performance never before attempted in electric railway practice. In most cases the traffic on inter-urban lines is conducted by means of train orders given by telephone. The train despatcher has his office located in some convenient spot, and the telephones are placed in cabins or booths or in the sub-stations along the line. The train orders from the despatcher are received at the telephone cabins by the conductor or motor man, and are repeated back to the despatcher by the man receiving them, the other man standing by and hearing them repeated. The orders are all received verbally, and no record is kept of them. No car is permitted to leave a telephone station until such an order has been received and repeated. This method seems to be cumbrous and out of date. On single lines the use of the electric train staff or tablet would be simpler and quicker, and would, I believe, add largely to the safety of the traffic. The instruments should be of such a nature that they could be operated by the conductors. By the courtesy ot the Chief Engineer of the General Electric Company I have particulars of several more inter- urban railways similar to the above, but enough has been said to show what great developments are taking place in this respect in the United States. Such lines are becoming of increasing importance, population becomes more numerous in their vicinity, land values are enhanced, industrial enterprise is stimulated, and the convenience of the public is served by a frequent and cheap means of transportation not only for passengers, but also for freight. Farmers are said to appreciate the facilities thus afforded them for conveying their produce into the cities, and large quantities of milk are now daily carried into the markets by electric cars. Where steam railroads exist side by side with the electric lines, the competition between the two has been keen. Steam roads having seen a large share of their passenger business taken from them, have made a hard fight to retain the local freight business. But it would appear that the increased prosperity and activity in a district^ which are promoted by the presence of an electric line, result in bringing more business to the steam lines. So that while the electric lines will probably carry the local traffic, passenger and freight, for short distances, they will act as feeders for the through business of the steam roads. In other words, there is a place for each, and their interests are best served by working in harmony. The experience gained in America in regard to electric inter-urban railways should be of great value to those engaged in the construction of similar lines, under the name of " light railways" in this country. American engineers have discovered that ' a modern first class electric railway should have a location that will admit of the most direct route with as few curves as possible, and be so laid out as to curves as to have them as easy as possible." It has been found not only desirable but " most economical to purchase private rights of way," to use heavy rails, large ties, and plenty of good ballast. Experience has proved that a substantial, well laid track is a "vital factor" in the economical operation of such a road, and a " large factor " in its earning capacity. The question of the best type of car for such railways is still receiving much attention in the State8> and has not yet been finally decided, but it is found 13875 C 18 that a heavy substantial vehicle is necessary, and that the wheels should have deep flanges, broad treads, and strong axles. In some instances, as for instance on the Schenectady- Albany line the depth of the flange is limited by the grooved rail over which the cars have to run within city limits, but where high speeds are aimed at, safety requires that the wheels and wheel flanges should be similar to those employed on fast steam roads. In England the electrical inter-urban railways, which have been constructed under the Light Railways Act of 1896, differ in every respect from similar lines in America. They are almost invariably laid alongside the high roads, have light rails, and insufficient ballast, while the cars employed on them are mostly double-decked and have tramway wheels with small flanges. Such lines are nothing more than tramways, and quite unsuitable for high speeds. If railways of this nature are to be as successful here as they are in America, their owners must, I venture to think, profit by American experience, and follow American methods. Descriptions of many other objects of interest will be found in my diary, and need not be repeated here. In conclusion I have to express my grateful acknowledgments to my numerous American and Canadian friends, who did all in their power to make my visit to their country enjoyable and instructive. The President of the United States, to whom I paid my respects, gave me a friendly welcome, and all with whom I came in contact, without exception, spared neither time nor trouble to assist me in my enquiries, and to make me feel at home. Wherever I went I was cordially received, and invitations were tendered to me to extend my tour through the whole length and breadth of the country, of which, I hope, I may be able to take advantage on some future occasion. I have the honour to be, Sir, Your obedient Servant, H. A. YORKE, Lt.-CoL, R.E. DIAKY OF TRIP TO AMERICA September 19th to October 31st, 1902. Friday, September 19th. Sailed from Liverpool at 5 p.m. on board White Star S.S. "' Celtic." Sunday, September 2Sth. Arrived at New York at 8.30 a.m. After passing baggage through the Customs, reached the Waldorf Astoria Hotel at 11 a.m. Monday, September 29 th. I went to the Grand Central Station and called upon the officers of the New York Central and Hudson River Railroad. Spent the day inspecting the Central Station, the signalling and working of the traffic through the yard, and all the arrangements connected therewith. The signal cabin contains 147 levers in use, the points and signals being operated on the low pressure pneumatic system, installed by the Pneumatic Signal Company, of New York. The yard is very much congested, and the traffic operated under great difficulties. Many of the passenger trains are " fly-shunted " into the station, the engine taking one track, and the train being switched into another. The train travels into the station by its momentum, being controlled by the hand brakes, the air brake being held in reserve in case of emergency. The operation is risky, but has, hitherto, I was told, been unattended by any mishap. I also visited the office of the American Express Company, and saw the method of handling baggage and express freight. Tuesday, September 30th. At 9.30 a.m. I went by the j Elevated railway to call on Mr. Westinghouse at his office at 120, Broadway. Mr. Westinghouse was not in the city, but I was received by Mr. Galvert Townley, who had been told by Mr. Westinghouse to look out for me, and assist me. I went with Mr. Townley to call upon and present my letters of introduction to Mr. E. P. Bryan. General Manager of the Rapid Transit Subway Construction Company, and Mr. W. B. Parsons, Engineer- in-Chief to the Rapid Transit Commission. Both gentlemen received me with much friendliness, and promised me every facility for seeing the Rapid Transit Subway at present under construction. Fixed the date and time for my visit to the subway works. The day was mostly occupied in making arrangements for my future movements. Wednesday, October 1st. Mr. J. N. Beckley met me at the hotel and arranged for a trip to Chicago and the West. At 10 a.m. I went to Mr. Westinghouse'* office and found that gentleman there. He received me most cordially and arranged for me to go with him on Friday, 3rd inst., to Pittsburgh. I then went to call upon and present letter of introduction to Mr. A. Skitt, Vice-President of the Manhattan Railway Company, and obtained from him the necessary permission to visit the line, which is better known as Ihe Elevated Railway of New York. Thursday, October 2nd. I met Mr. G. S. Rice, Assistant to the Chief Engineer of the Rapid Transit Commission, and accompanied him over a section of the new subway. The works are on a very large scale, the excavation being to a large extent through very Lard rock, about 300,000 cubic feet of rock having to be removed out of a total of 3 million cubic yards. The length of the line is 21 miles (7 miles being four track and 14 miles double track), and the total estimate is 35 million dollars, out of which about 21 millions have been expended. An enormous number of drains, pipes, and conduits have had to 13875 2 20 be diverted, and the street traffic has to be continued without interruption. The condition of some of the streets where the work is in progress is deplorable. The subway provides for four tracks, two for express trains, and two for local trains, and no portion of the work is yet open for traffic. The subway is rectangular in section, and is constructed wholly of steel uprights and girders, with concrete floor, walls, and roof. The concrete is of a high quality, the cement (of American manufacture) being exceptionally good. Every effort is being made to render the whole subway absolutely waterproof from end to end. In the afternoon I called on Mr. Yreeland, President, Metropolitan Street Kail way Co., and afterwards went with Mr. M. G. Starrett, Chief Engineer of the Company, to see the power house of the street railways and to inspect a portion of the track. These street railways are worked at present partly by horse traction, partly by cable, and partly by electric power, but they are being converted throughout into electric lines on the " conduit system." The rails are of various descriptions and weights, arid the track in many places is in a bad condition. It is, however, being gradually relaid, a grooved rail being now adopted as the standard, the groove being wider than is usual in England. The traffic on these tramways, or surface lines, is very great, the cars being always full, and at certain times of the day crowded. The fare is 5 cents for any distance. Tickets are not issued, but when necessary " transfers " are given by the car conductors at places w r here different routes intersect, so as to enable a passenger to change from one car to another without further payment. A check is kept upon the conductors by means of a registering machine in each car, which has to be operated by the conductor every time a fare is paid, and which thus records the number of fares paid. Both single truck (or four- wheeled) cars and double-truck (or bogie cars) are used upon these lines, there being altogether about 2,600 cars in use. The cars are fitted with a hand brake only and with a life guard of a type which is of little or no use. The schedule speed is eight miles an hour, including stops, but " down town " the speed is very much less than this. The power station visited by me contains 88 15. and W. boilers arranged in three tiers and 11 engines of 5,000 H.P. each, of which six are running. The generators are 3,500 K. W. machines producing current at 6,600 volts (alternating), which is transformed in static transformers to 370 volts (alternating), and then converted in rotary converters into direct current at 575 volts. The chimney of the power station is the highest in New York, being 353 ft. high, with an internal diameter of 22 ft. Friday, October 3rd. I left New York at 7.40 a.m. with Mr. Westinghouse in his private car for Pittsburgh, travelling by the Pennsylvania Railroad viu 'Philadelphia and Harrisburgh. Had a very pleasant and interesting journey by daylight over this fine railroad, which is the premier line in the States. The scenery in places is very attractive, especially in the Alleghany mountains and when passing round the celebrated Horse Shoe curve. The railroad consists of four tracks and is laid with heavy rails (flatbottomed as is usual in the States) and broken stone ballast. It is in fine order, and is apparently as good as the best type of English road. We arrived at Pittsburgh at 7 p.m. and went direct to Mr. Westinghouse's private residence at Holmwood. I should .mention that the line from New York to Pittsburgh is signalled throughout on the automatic (electro-pneumatic) system, which is said by the railway officials to be entirely satisfactory. Saturday, October 4th. At 8.30 a.m. I visited the Union Switch and Signal Co.'s works (the company is one of the Westinghouse undertakings) and spent the whole morning with the general manager examining the details of the electro-pneumatic appliances for operating points and signals and for automatic signalling. There is a large gallery fitted up with a circular track and a complete installation of automatic signals. A model train actuated by electricity travels round the track and exemplifies the working of the . signals, &c. In the afternoon I visited the Pittsburgh railway station and signal cabin. The station, which is new, contains 16 tracks and is well provided with waiting rooms, &c. The waiting accommodation at important modern American 21 stations is very complete and far superior to anything to be found in England. In addition to large waiting halls, well warmed and fitted with ample seating accommodation, there are comfortable rooms for women containing all sorts of toilet requisites and conveniences, even cots for babies being provided ; there are also smoking rooms for men, and barber's shops, besides baths and lavatories of a superior description. The restaurants are excellent and the kitchen arrange- ments are of the most modern type and supplied with every labour-saving appliance for cooking and washing up. The station yard is laid out and signalled in the most approved fashion, the points and signals being operated by the electro-pneumatic system from the signal cabin, which contains 131 levers, of which 12 are spare. A cabin such as this contains about five or six men, viz., one to watch the traffic from the window and give directions to the men at the frame ; one to attend to the telephones and receive from and send to the station staff information relative to the departure and arrival of trains ; one to make entries in the train register of the movement of trains ; and two or three at the frame itself. In England such a cabin would not contain more than two, or at the most, three men. Movable crossings and spring frogs are used throughout the yard and are said to answer very well. Sunday, October 5th. I drove round Pittsburgh which is a very smoky place, the city being as black and grimy as London, but the scenery round the place is good. Monday, October 6th. At 8.30 a.m. I went to the Westinghouse Brake Company's works with Mr. Herman Westinghouse, who is the President of that Company. This, which was the first of Mr. George Westinghouse's undertakings, is still one of the most important, as it practically has the monopoly for supplying the whole of the American railways with brake gear. I examined the details of the " High Speed Brake " and the "'Rapid Acting Brake," the former being a development of the latter. The High Speed Brake is as the name implies suitable only for heavy trains travelling at very high speeds. It requires a pressure of 1 1 Ibs. of air when it is first applied, and is fitted with a reducing valve, which, as the speed of the train diminishes, gradually reduces the air pressure to the normal pressure of 75 Ibs. The object of this device is as follows. If the pressure of 110 Ibs. were applied to brake blocks acting on wheels revolving at moderate velocities, and carrying only moderate axle loads, it would cause the wheels to skid. On the other hand the normal pressure of 75 Ibs. is not sufficient to produce an immediate effect upon wheels revolving at high speeds, and probably carrying heavy axle loads. The high pressure is therefore necessary for the high speeds, but if continued too long, i.e., after the original speed has been diminished, it would cause the wheels to skid. For this reason the high pressure after its first application is automatically and gradually reduced to the normal pressure of 75 Ibs. From time to time references to this appliance have appeared in the English papers, and our English railways have been urged to adopt it, and have been blamed for not doing so. But as a fact the responsible officers of the brake company do not consider that the High Speed Brake is necessary, or indeed suitable, for English conditions, because unless employed with the greatest care on English trains it would lead to the skidding of the wheels. Moreover, not many English Companies use the Westinghouse brake, the majority of them having the vacuum brake. The Rapid Acting Brake employs air at the normal pressure of 75 Ibs., and the feature of it is the rapidity with which it acts upon every coach in a long train, so that the interval of time between the application of the blocks upon the front and rear wheels of a train, however long, is inappreciable. Its action is in fact instantaneous throughout a train, and a train can therefore by its means be stopped very quickly. Those English companies which use the Westinghouse brake might, with advantage, adopt the " Rapid Acting" type. I also examined all the details of Newell's magnetic brake for tramways and street railways. The invention is that of a Mr. Newell, an engineer of Chicago, and the Westinghouse Company has bought up. the rights. Much 99 time and care have been spent in perfecting the appliance before placing it or. the market, but it is now being manufactured on a large scale. It is a slipper, or track, brake, consisting of an electro-magnet, which is excited by current generated by the motors acting as " generators." The slipper, when thus magnetised, is strongly attracted to the rails, and acts as a very powerful brake. The slipper is also connected to brake blocks on the wheels by a system of levers in such a way that the drag on the slipper caused by its adhesion to the rails, presses the blocks against the wheels, so that the magnetic brake operates as a wheel brake as well as a track brake. Resistances are provided, which automatically regulate the current in the magnets, and these resistances are utilised in winter for heating the car. I believe this brake is one of much value for tramway purposes. I was then shown the Westinghouse Friction draw gear, which has been designed to absorb the shocks produced on the draw bars by the starting or stopping the large freight cars, now in such general use on American railways. It is said to give good results, and is being largely adopted throughout the States, with the consequence that broken draw bars are less frequent. Another ingenious device shown to me was an automatic coupler for automatically coupling the brake pipe, and (for passenger cars) the steam heating pipe as well. This coupler is an unsightly object, but may prove to be useful. At present the advantage of the automatic draw gear coupling between freight cars is partly neutralised by the necessity which exists for men to go between the cars for the purpose of coupling or uncoupling the brake pipe. It is, therefore, evident that if this latter operation can be performed automatically at the same time as the former, the risk of injury to the men will be still further reduced. In the afternoon I went to the Westinghouse Electric Works. These are very extensive and are equipped in the most modern fashion. Here every description of electrical machinery is manufactured, such as generators, motors, transformers, converters, switch boards, controllers, &c. I saw some exceedingly large alternating generators being built, the external diameter of which was 42 ft., the diameter of the revolving armature being 32 ft. I examined the Westinghouse method of pneumatic control for multiple unit trains, which seems to possess the great advantage that no high voltage electric currents are introduced into the driver's compartment or carried through the train, the movement of the controller switches being effected by compressed air, supplied from a reservoir charged by means of a motor-compressor. The valves regulating the admission of the air to the controllers are operated by electro- magnets energised by low tension currents from a local battery, these currents being manipulated by the driver's handle. A very large shop, 1,200 ft. long, is devoted to the manufacture of motors for railways and tramways. The company are manufacturing eight large generators for the Manhattan Elevated Railway of New York and eight others for the New York Subway. Tuesday, October 7th. At 9 a.m. I started on an electric car, which the management kindly placed at my disposal, to examine the street railways, or tramways, of Pittsburgh, which are operated by the Pittsburgh Railways Company, a recently formed combination of several separate companies. The system comprises about 250 miles of track, equal to 125 miles of double line. The track is laid with a variety of sections of rail, but a " step " rail is now the standard. This rail has a depth of nine inches and a weight of 90 Ibs. per yard. It is laid on cross ties or sleepers, the latter resting on ballast without any concrete. The old tracks are in a very indifferent state of repair, but the new track is good. The section of rail though not one suitable for English streets, and one which is being discarded in most American cities, appears to be popular in Pittsburgh because it affords a convenient track for heavy lorries or " teams," the gauge being 5 ft. 2J ins. The gradients in many places are steep and the curves are sharp, the worst having radii of 50 ft. The speeds attained are high according to English ideas, especially when the congested state of. the streets in Pittsburgh is considered, while outside the busiest portion of the city the cars travel at speeds of 25 to 30 miles an hour. The cars are mounted, some on 4-wheeled (single) trucks, aud some on miles of track, and the Surfo.ce lines of 385 miles of track, in all cases measured as single line. The subway was originally designed for tramcars only, and it was at a later date that it was decided to devote two of the tracks in it (in places where there are four tracks) to the use of the trains from the Elevated railway. In this way it has come about that there are in it many curves and gradients, which though not unsuitable for tramcars are a serious obstacle to the Elevated trains, the service upon which suffers accordingly. I spent some time on Friday evening watching the traffic passing through Park Street Station on the subway. This is one of the busiest places on the subway, and in the evening the number of passengers is great. There are four tracks through the station, two for the tram lines and two for the elevated trains. The tram lines are in the middle and terminate here in a loop, the tracks used by the elevated trains being outside the others, and separated by a sufficient space to make room for the loop. The tramcars from all the routes pass through this place in an endless succession, each car being conspicuously marked to indicate its route. The crowd is so great at the busy hcur that a special force of inspectors is employed to prevent people from boarding the cars while they are in motion. The tramcars run singly, but the trains of the Elevated railway consist of four cars. i 13875 D 2 28 Saturday, October llth. I spent the morning on the Elevated railway, and the afternoon on the Surface or tram lines. The Elevated railway, which is 6J miles long, comprises about 16 miles 01 track including sidings, laid with 85-lb. rails, the third rail (or conductor rail) weighing 100 Ib. per yard. As its name implies, the Elevated line for the most part is carried on a steel viaduct along the streets, but, as already stated, in places it passes into and through the subway. The whole 01 the steel structure is bonded and connected with the power station so as to assist in acting as a return conductor. On the whole it is a more substantial structure than the elevated line in New York, advantage having been taken of the experience gained in the latter city. Where, as often happens, the street tramways pass below the elevated line, the trolley wires of the former are attached to the underside of the viaduct, being at the same time doubly insulated therefrom. There are 120 cars on the elevated railway, and the trains consist of three or four cars. Each car has two bogie trucks, on one of which are placed two motors of 150 H.P. each, making a total H.P. on each car of 300, there being a controller at each end of each car. The trains are fitted with the Westinghouse automatic air brake, the air for which is supplied by an electric air compressor on each car. The controllers are of the Sprague multiple unit pattern, the handles of which fly back to the " off" position if let go. This ensures that if anything happens to the motor-man the trains shall come to rest. The current is supplied from the power stations, of which there are seven for the whole system, elevated as well as surface, at 550 volts (direct). The cars have each four " shoes " or " slippers " for collecting the current from the third rail, the latter being placed outside the rails in the space between the tracks. The wheels have 4], in. treads and flanges l in. deep. The line is signalled throughout on the electro-pneumatic automatic system, the insulated joints between the sections being placed in each case 200 ft. beyond the signals marking the entrance to the sections. Alongside of the signals and working in conjunction with them are placed automatic triggers which apply the brakes should a train overrun a danger signal. This installa- tion of automatic signalling is unusually interesting, as it is the first instance of this system being introduced on an electric railway using the rails (or one of them) for the return of the propulsion current. Track circuits for signalling purposes require the exclusive use electrically of at least one rail of each track to which the signals refer. Under ordinary conditions it is not found feasible to surrender one of the rails for this purpose. But on the Boston Elevated Railway, owing to the great capacity of the elevated structure as a return conductor, it was found possible to devote one rail entirely to block signalling purposes, the other rail being common to both the block and the propulsion circuits. Special means were devised to prevent the operation of the signals, or the damage of their controlling mechanism, in case the propulsion current should find a return through the block rail and instruments, and polarised relays had to be used so as to respond to currents in one direction only. The problem seems to have been cleverly solved on this line. The electrical energy for the block system is supplied by four motor generators placed in convenient places, driven by current drawn from the main propulsion feeders, and delivering current at 90 volts, which by means of resistances is reduced to 15 volts in the track circuit The air for operating the signals is supplied from air compressors fixed at the terminal station, these also being driven by energy drawn from the main feeders. A very completely equipped school is provided for the instruction of the motor- men in all the details of the controllers and brake equipment, and the men have to pass a strict examination, and are also tested for eyesight and colour blindness, before being allowed to take charge of a train. The training of motor-men for Surface lines and all electrically operated railways appear to be more thorough in America than it is in England. Sullivan Square Station, where the elevated trains and surface cars meet and exchange traffic, is a very interesting place and is admirably planned. This is a terminal station for the Elevated trains, which here run round a single line loop, one side of which forms a single track through the middle of the station while the other makes a circuit outside. The surface cars run into the station 29 on either side of the centre line, there being altogether 10 tracks (five on each side) devoted to them. These tracks form dead end bays, or as they are called in America " stub tracks." The elevated trains run at two minutes' interval, which is found to be the shortest that can be obtained with the signals arranged as at present, but it is contemplated to fix the signals nearer together so as to enable a still more frequent service to be obtained. At junctions and places where there are switches to be operated, electro- pneumatic interlocking plants have been erected. A good deal of trouble is caused by the sharpness of the curves on the subway section of the elevated railway. These curves not only affect the speed but have a very injurious action upon the wheels, upon which a series of ridges is soon formed, owing to the slipping of the wheels round the curves. The wheels have at very short intervals of time to be taken into the repairing shop, where instead of being turned in a lathe they are ground true by means of a grindstone. This is found to be quicker than turning them. At Dudley Street Station on the Elevated railway the surface cars again exchange traffic with the elevated trains. This is a terminus for both elevated trains and Surface cars, all of which run round single line loops instead of into stub tracks. In fact, loops form a marked feature of most electric railways in America, as they do on the Metropolitan Railway of Paris, as I pointed out in my report last year. In the afternoon I travelled over a. section of the surface lines or tramways. These are at present laid with a variety of rails, but the grooved rail, with a wider groove than is usual in England, is now adopted as the standard. It weighs 80 Ibs per yard. Where the vehicular traffic is heavy, especially where heavy lorries, or " teams " as they are called, are numerous, the " step " rail or tram rail is used. Outside the city the lines are laid on the grass alongside the roadway, and here an ordinary T railway rail is employed, which is laid with its upper surface level with the grass, the latter being brought close up to the rails on all sides, both between the rails and between the tracks. The Surface lines are practically double throughout, this being a feature of most American tramway lines, single lines not being approved. The cars on these tramways are chiefly bogie cars, and a few of them have maximum traction trucks, which, however, are found here, as elsewhere, to be unsatisfactory. Some cars are four-wheeled, but these are said to be hard on the track, and are not liked by the management. All the cars have two motors, those on the bogie cars being of 40 H.P. each, and those on the small four- wheeled cars being of 30 or 37 H.P. each. The cars are all fitted with the ordinary hand brake, but no emergency brake. They have life guards or fenders of three different patterns, none of which can be regarded as satisfactory. The tracks are laid on cross ties at about 2^ ft. centres, and concrete is placed between the ties, but not underneath them. This is a very usual mode of construction in America, but I cannot help thinking that the concrete is in the wrong place, and that it would be better below the ties, or at any rate below the rails as is the custom in England. Heavy iron gauge rods are used to keep the track to gauge. The speeds in the city streets is low, not exceeding six or eight miles an hour, but outside the town the cars are run at a speed of 20 to 25 miles an hour. The motor-men are well trained and handle their cars with care and skill. The Company have to run some postal cars for the collection and distribu- tion of letters under contract with the Post Office. The overhead trolley system of traction is made use of, the current being supplied from seven power houses, the voltage being 550. The same power houses supply also the elevated lines. As already stated, the tram lines pass into the subway at certain spots and use the same stations as the elevated trains. As a general rule the termini of the tram lines are formed by means of single line loops and not with cross-over roads. 30 Sunday, October 12th. I spent the morning examining the Boston South Station belonging to the Boston Terminal Company, which is an association of the five companies which run into it, viz., the New York, New Haven, and Hudson River Railroad Company, the Boston and Albany Railroad Company, the New England Railroad Company, the Boston and Providence Railroad Corporation, and the Old Colony Railroad Company. This station is a remarkable structure, its most attractive features being the waiting halls, toilet rooms, and restaurant. The main car shed covers an area of 506,430 square feet, and the whole of the building is built on piles over which a concrete foundation has been placed. The roof of the car shed is ugly, being of a flat arched shape with a covering of tarred felt or paper. The result is that the interior of the shed is dark, except when lighted artificially. Steam pipes have been laid along all the valleys or gutters of the roof, for the purpose of thawing the snow and preventing any accumulation of it. The arrangements for heating and lighting are very complete, and the kitchen and feeding arrange- ments are admirable and far beyond anything that exists in England at any station. I attach a printed statement giving a number of statistics concerning this station, about which a great deal has from time to time been said by English visitors. From this it will be seen that the greatest number of trains in both directions which use this place daily is 801, and the number of passengers per annum is 25 millions, or 68,500 per diem. Comparing this with Liverpool Street Station in London, where the daily trains number 1,060, and the daily passengers on very busy days reach the large total of 179,680, it will be seen that, in spite of all that has been said, the operations at Boston are not so large as those here. And this fact becomes the more notable when it is remembered that at Liverpool Street there are onlv 18 platform lines as against 28 at Boston, and only six tracks leading into the fprmer as against eight at the latter. Again, at Cannon Street Station, where there are nine platform lines and one middle road, with eight lines leading to and from them, the number of trains dealt with daily is 920, and at Charing Cross, with six platform lines and four tracks in and out, the number of trains handled is 550 daily. The station yard at Boston is very well laid out, and the permanent way is good. Moveable frogs and spring frogs are largely used ; and here as elsewhere the former are well spoken of, but the verdict in regard to spring frogs is not so unanimous, some engineers approving of them and others disliking them. The signalling throughout the yard is on the electro-pneumatic system, all the switches and signals being worked by power from three signal boxes, which contain 165 levers. About half a mile outside the station there is a bascule opening bridge of the rolling type. This bridge has two spans each of which weighs 500 tons, five-eighths of which is counterweight. The bridge is opened and closed by electric power, but owing to the skilful way in which it is balanced by the counterweights the electric energy required to operate the bridge is exceedingly small, the cost of each operation of opening and closing being only 2 cents. This type of opening bridge is very common in the States, there being several in Chicago and elsewhere. Below the main station there is a subway to accommodate local trains. In this there are two loop single line tracks, so that the local trains can run through the station, and all shunting or shifting of the engine from one end of a train to the other is avoided. There are four tracks through the yard for these local trains. The subway is not yet in actual use. . In the afternoon I visited the public library in Boston, which is a fine building and admirably appointed. The facilities afforded to the public by these free libraries is remarkable, even children having large rooms ses apart for them in which suitable books are provided. I. then went to Hartford, and after dinner I was taken to see the power house of the Hartford Electric Lighting and Power Company. The chief source of power utilised by this Company is water, two water turbines having been erected 10 miles away, viz., one of 2,000 H.P; 31 and one of 1,600 H.P., the current there generated being 10,000' volts alternating. This is 'conveyed to Hartford on overhead conductors j it is then transformed to 2,400 A'olts, at which voltage it is distributed to several works, but for use in the centre of the city it is still further reduced, and is supplied at 220 A'olts direct. The most interesting feature was the steam turbine, which has been erected in the power house to supplement the water poAver, should that fail. The steam turbine Avas adopted because of its lower first cost as compared with a reciprocating engine ; its smaller cost of installation ; its relatively high efficiency at fractional loads ; and the email space occupied by it. It Avas supplied by the Westinghouse Electric and Manufacturing Company, and has a rated capacity of 2,000 kiloAvatts, Avhich can be increased by superheating. The steam is supplied by three Aultman-Taylor water tube boilers, each having a rated capacity of 500 H.P., which however can be increased by superheating. This turbine has given entire satisfaction, and though it is not often called upon to supply energy, it is kept always ready in case of emergency and for use Avhen the Joad is excessive. Monday, October 13th. I left Hartford at 8.33 a.m. and reached New York at noon. In the afternoon I met Mr. Potter of the General Electric Company, and Colonel Heft, electrical engineer of the New Haven and Hartford Railway Company. Tuesday, October l-ith. I went over to Brooklyn at 10 a.m., and called upon Mr. Calderwood, assistant to the president of Brooklyn Rapid Transit Company. I then visited the surface lines of that Company. These lines are a consolidation of the lines of six formerly existing companies, five of which possessed surface lines, and one an elevated railway, in Brooklyn. The total mileage now owned or leased by the Brooklyn Rapid Transit Company is about 250 miles of double track, of which 28 miles form the elevated railroad. A new power-house is being built containing 32 boilers on two floors, each boiler having a capacity of 600 H.P., and eight engines of 4,500 H.P. each. There are two direct current generators (550 volts) of about 4,OuO H.P. each, and six alternating current generators (6,660 volts) also of 4,000 H.P. each. The surface lines are Avorked on the overhead trolley system, and the elevated railroad on the third rail system, the voltage in both cases being 550. The surface lines are now being laid with grooved rails in 60 feet lengths, which haA r e been adopted as the standard, the grooA'e being a wide one, and so shaped as to be self cleaning. Outside the city limits the surface cars run upon the same rails as the elevated trains, the speed attained being as high as 25 miles an hour. Inside the city speed restrictions are imposed of 8, 10, and 15 miles an hour. The cars, as is the universal custom in America, are " single decked," The rails are laid on cross " ties " or sleepers, concrete being filled in between the ties, as is the case in Boston and New York and elsewhere. 2\lthough, as already stated, I do not think this is a good way of using the concrete, it undoubtedly makes a quiet and elastic road, but it is most difficult to maintain and does not afford such a good surface to the street. The condition of the streets is, however, not regarded in America as so important as It is in English towns. . The elevated railway is similar to that in Boston, already described, and to that of New York, which AA r ill be described hereafter. The third or conductor .rail is laid outside the track rails, and the current is collected by shoes or , slippers, of which there are four on each motor car. The trains consist of fiA r e cars, viz., three motor cars and two ordinary cars. The motor cars are fitted .with the Westinghouse pneumatic multiple controllers. The motor cars have ,twQ motors of 150 H.P. each, on the same truck, the wheels carrying the motors being 33 inches in diameter and the other Avheels 30 inches. ; Both the surface cars and the eleA^ated trains tra\-el over the Brooklyn bridge into NCAV York, separate tracks being provided for them respectively, the : elevated .tracks being in the centre of the bridge and the tramway tracks one on one side of the bridge and the other on the other side. The bridge is .not 32 regarded as sufficiently strong to allow the surface cars to follow each other close together, and an interval of 100 feet has to be maintained between them. I was disappointed with the Brooklyn Bridge, of which I had heard and read so much. It is constructed of steel wire ropes, there being eight such ropes in each of the four main cables. The slings supporting the floor girders consist of similar ropes, one rope to each sling, and these are attached to the main cables by iron straps or clips. One of these clips failed a short time ago and created a good deal of alarm, and it was in consequence of this that the regulation was made as to the distance of 100 feet being maintained between the tram cars passing over it. The total length of the bridge is 5,989 feet, of which the central or river span is 1,595 feet. It is interesting to compare this with the Forth bridge, the two main spans of which have each a length of 1,700 feet. The Brooklyn bridge does not give one an idea of great strength, and is not such an imposing structure as I was led to expect. The elevated railway of Brooklyn terminates at the New York end of the bridge in a station raised above the street level. The surface lines after passing over the bridge descend to the street and spread out into four tracks, which circle round the end of the bridge, forming four single line loops. The congestion of traffic here at the busy times of the day, morning and evening, is great, and forms one of the sights of New York. Many schemes have been proposed to remedy this state of affairs, but no solution of the difficulty has yet been found. The problem is worse now than ever, since the number of cars allowed upon the bridge at one time is limited. Wednesday, October lath. At 9 a.m. I met Mr. Potter, chief engineer of the Railway Branch of the General Electric Company, and went with him over the Manhattan, or New York, Elevated railway, which is now in process of being- prepared for electric traction by the General Electric Company. This line has hitherto been worked by steam, but many of the trains are already being operated by electricity, both steam and electric trains using the same rails. The line is supported on steel colums and girders, the level of the rails being about that of the first floors of the adjacent houses. The permanent way has no continuous flooring, the space between the ties being open. This has been done in order not to shut out the light from the street below, but it is presumed that some inconvenience must have been caused by ashes or water dropping from the steam engines into the street. e> The length of the Manhattan Elevated railway is 55 miles of double track, and the number of cars in service is 1,0X9, equal to about 230 trains. The trains as a rule consist of five cars, when drawn by steam locomotive, and six! cars when electrically propelled. The minimum interval between trains is 57 seconds, but the average interval is much more than this. The average speed attained by the steam trains is said to be from 13 to 14 miles per hour, including stops, but as the latter are very numerous, the distance between stations being about 575 yards, the actual speed between stations must be much higher. The above figures relate to the stopping trains, but there are four tracks on some of the routes, two of which are reserved for express traffic, and on these the schedule speed rises to 26'4 miles per hour. With electric traction higher speeds than the above are expected. The trains in the busy time of the day, viz., between 5 and 6 p.m., are densely crowded and very uncomfortable, it being almost impossible to get a seat, and difficult to force one's way into or out of a car oAving to the crowd of passengers standing in the centre passage and end gangways. The platforms u down town "are thronged with people waiting for the trains, and railings are fixed to prevent persons from being forced on to the line, gaps being left in the railings opposite the gangways between the cars. Marks are placed in the six-foot way to guide the motormen in stopping the trains in the right place, so that the gangways may be opposite to the gaps in the railings. \ The electric trains are divisible into two units of three coaches each, and during the middle of the day the trains are so split up. Each unit has two motor cars, viz., one at each end with an ordinary car in the middle. In this way the full sized train of six cars has four motor cars, two in the middle and 33 one at each end. Each motor car has two motors of 125-H.P. each, both motors being on the same bogie truck. The wheels carrying the motors are 33 inches in diameter, the others 39 inches. The sharpest curves on the Manhattan railway have radii of 90 feet and the steepest gradient has an inclination of 2 per cent, or 1 in 50. These curves are a drawback, and where they occur speed has to be reduced to eight miles an hour and even less, partly on account of the risk of derailment, and partly because the motorman cannot see round the curves, and does not therefore know whether the line ahead is clear. The line is not signalled, except at the curves, and the motormen regulate their movement in accordance with that of the train ahead of them. The service is in fact worked in the same way as that of a tramway. At the curves automatic mechanical signals are provided, which indicate to a driver of any train whether the previous train has cleared the curve or not. These are operated by treadles alongside the track. Flag men are also stationed at some of the worst curves. At switches and crossings, where such exist, ground signals are provided, which are interlocked with the switches and are operated from small ground frames. The absence of block signals has hitherto been found to introduce no risks, the speed of the steam-driven trains being low. But with the introduction of electric traction, with its high speeds and higher rate of acceleration, viz., two feet per second per second, it seems probable that signals will be required, though at present it is not intended to provide them. Without them accidents will almost certainly occur. The tracks are everywhere provided with inside check rails and outside timber wheel guards. The whole structure is bonded electrically and connected with the rails, which form the negative conductor. The trains are fitted with the Westinghouse automatic air brake, air being supplied from compressors on each car driven by small auxiliary motors. The controllers are of the General Electric Company's pattern, which enables any number of units to be controlled from any car. The controller magnets are placed underneath the car, asbestos sheets being attached to the underside of the car above the magnets. If the motorman lets go of the controller handle the current is at once cut off, and cannot be restored until the controller handle has been moved to the " off " position and then moved forward again. The removal of the reversing handle locks the controller handle, so that all the motorman has to do when he leaves his compartment is to remove the reversing handle and the controller is then out of use. This enable's the space occupied by the motorman to be used by passengers when not required for driving. The cars are mostly the old ones, formerly used in the steam trains, and which have been equipped for electric traction, for which, however, they do not seem well, suited. The track is laid with 80-lb. steel rails, and the conductor rail is of the same weight and section. The latter is placed outside the running rails in the six- foot way. The main transmission and feeder cables, from the power house to the substations and from the latter to the line, are also carried on the top of the girders of the railway in the six-foot way, an arrangement which is open to much objection, as, if an accident occurred such as the derailment of a train, and a short circuit were thereby caused, the results would be very serious and probably disastrous. But in such matters Americans seem prepared to " take chances " which would not be thought of in England. The power house of the Manhattan railway contains eight alternating generators of 5,000 kilowatts .each, there being two compound condensing engines to each generator, steam being supplied from 64 Babcock and Wilcocks' boilers arranged on two floors. The current in the first instance is 11,000 volts (alternating), which is transformed down in the substations to 390 volts, and afterwards converted by rotary converters into direct current at 600 volts. The 13875 E 34 power house has four chimney stacks 280 feet high. Rouey mechanical stokers are used, whereby only one third of the staff, which would otherwise be required in the boiler room, is needed. The operation of preparing the line for electric traction while the trains are still running is highly dangerous to the men employed, the intervals between trains being so small, and there being little or no space in which the men can take. refuge. I saw one unfortunate man run down and killed by an electric train a short distance ahead of the train in which I was travelling. In the afternoon I had a very interesting trip to the mouth of the harbour on board a steamer with " Curtis " steam turbines to drive her. The great feature of these turbines was the extremely small space occupied bv them, and their smoothness of running and absence of vibration were also remarkable. The steamer had twin screws driven by two turbines, each of 1,250 H.P., and the engine room was about ten feet square. The Curtis turbine is similar in principle to the Parson's, but differs somewhat in detail. It has a reversing turbine fitted on the same shaft as the forward driving turbines, but enclosed in A separate steam chamber. When the engine is in forward gear the reversing turbine is running free, no steam being admitted to it. But when the engine is reversed the forward turbines run free, while steam is admitted to the reversing turbine. The operation is instantaneous in action and very .simple. Owing to the speed of revolution being exceedingly high a special form of screw is necessary, otherwise a vacuum is produced by the screw which impedes the forward movement of the ship. A thoroughly satisfactory form of screw has not yet been discovered. Thursday, October 16th. At 7.30 a.m. I went to Philadelphia, arriving there about 11. I spent the morning in Baldwin's locomotive works, where they turn out 2,000 locomotives a year, or more than 6 per day, the greater number of which are for use in the States. The thing that struck me most here was the extraordinary congestion of the works, which are so filled with machinery, material, parts of engines, and engines in process of construction, that it was hardly possible to walk through the shops. It seemed to me that the men worked under much disadvantage in so crowded a place. A number of books were given to me explaining all the features of the Baldwin engines, and all the specialities for which the works are famous. The works are situated in the heart of the city, and though they cover a large area it appears that their size is insufficient for the amount of work turned out. This concern is remarkable in America in that it has not been converted into .a big public company. It still remains in private hands. I lunched with Mr. Cassatt, the president of the Pennsylvania railroad, Mr. Rea, vice-president, Mr. Pugh, another vice-president, and several of the chief officers of the line being also present. Mr. Cassatt is regarded as the most powerful railway man' in America. I then heard a good deal about the scheme already alluded to for tunneling under the harbour at New York so as to give the railroad access to that City. Mr. Richards, engineer of the Philadelphia Division of the line, and the signalling superintendent gave me all the information in their power on their practice in track work and signalling. The permanent way is similar to that already described as adopted on the New I ork Central railway. It is in tine condition and admirably maintained, -and as neat as care and attention can make it. Mr. Richards said that he had tried a mile or so of line constructed according to London and North Western method, and did not like it. But I do not think that he has tried the latest type of London and North Western road, nor do I believe that a test made under such conditions can be in any way regarded as conclusive. The whole of the four tracks between New York and Pittsbugh are signalled on ^ the automatic (electro-pneumatic) system of the Union Switch and Signal Company. The signals are operated by compressed air controlled by electric circuits in the track. The line is divided Into block sections about 1,000 or 1,300 yards long, a home and distant signal being placed at 3.5 commencement of every section. The arrangement is such that when a current is flowing along the track air is admitted to the mechanism operating the signals and the signals are pulled " off," i.e., to the safety position. When, however, any engine or car is in the section the track current is short- circuited, the air valves are closed, and the signal returns to " danger." The principle of automatic; signalling is good, but it is not easy to understand the advantage of splitting up the line into such short sections. The number of signals is bewildering, and it seems rather absurd to tell a driver who is, say, running at 50 or 60 miles an hour that the line is clear for no greater distance than 1,000 yards or so. The whole question of automatic signalling,, and its suitability for English conditions, requires more consideration than it has hitherto received. The Pennsylvania Railroad Company use cast iron wheels with chilled rims and flanges, not only on their freight trains, as is the general custom on all American railroads, but also for their passenger trains. The risk with these wheels is that the flanges are liable to be brittle and to break. If this happens a derailment is almost certain to occur. The advantage of these wheels is their cheapness. The manufacturing companies supplying them will always take back the old wheels at a good price, and break them up and recast them, so that the nett cost of the wheel to the railway company is very small, probably not more than 3 or 4 dollars. I returned to New York at about 6 p.m. Friday, October 17th. I left New York at 8.45 a.m., in the private car belonging to Mr. J. N. Beckley, president of the Toronto, Buffalo, and Hamilton Railway, and president of the Pneumatic Signal Company of New York and Rochester. Mr. Beckley, ou hearing that I was about to visit the States, communicated with me in England and most kindly arranged to make up a party of engineers and others for a tour to Albany, Buffalo, Niagara, Toronto, Detroit, Chicago, Washington, and back to New York, the trip to last about 10 or 11 days. In this way I was afforded an opportunity of visiting the places named and of seeing various matters of interest under the most favourable auspices. I was not disappointed, -for nothing was omitted to make the trip successful and instructive. The party at starting consisted of Mr. Beckley, General Eugene Griffin, late of the U.S.A. Corps of Engineers, and now vice-president of the General Electric Company of America, Mr. A. Spencer, director of the Railway Signalling Company of Fazakerly, Liverpool, Mr. W. Craven, of Craven Bros., Manchester, Mr. Hansel, vice-president of the Pneumatic Signal Company, and myself. We travelled by the New York Central Railroad to Albany, arriving there about noon. The car was there detached from the train and placed in a siding, while we all went by electric car to Schenectady over the new high speed inter- urban line. This is a good specimen of the class of railway which is being constructed in many parts of the States. The distance between Albany and Schenectady is 17 miles, the population of the former being 100,000 and of the latter 50,000. Hitherto the inhabitants have been served by the New York Central Steam Railway, which runs between the two cities, and the electric railway has captured about two-thirds of the passenger traffic from the older line and has at the same time built up an additional traffic of its own. It now carries 3,700 passengers per day. The line connects with the tramways in Albany and Schenectady, so that passengers have the advantage of travelling to or from the centres of those cities without change of car. The usual service between the two places is a car each way every 15 minutes, but in the morning and evening the interval is reduced to 10 minutes. There is also an all night service, the cars running every hour after midnight. An express baggage car runs every hour and freight cars every 45 minutes. The schedule time between the centres of the cities is 45 minutes, including stops, and including at least three miles over the tram lines, on which the speed has to be low. This gives an average speed of 23 miles an hour, but the maximum speed is as high as 50 miles an hour. The fare is 25 cents for the single journey and 40 cents for a return ticket. Books of monthly tickets are sold at a reduced rate. 13875 E 2 36 The line consists of two tracks laid on the public highway, of which they occupy about two-thirds, the remainder being a mere unmetalled roadway full of ruts. The railway is not fenced off, and the public have the right to walk or drive over it. B ut as the rails are laid on cross ties or sleepers and are raised above the surface of the roadway the public have little inducement to use the portion of the road occupied by the railway. The rails weigh 80 Ibs. per yard and are of the usual T section, except in the city of Albany where the ordinary grooved tram rail is laid, which weighs 110 Ibs. per yard and is of the girder section. The electrical equipment is on the overhead trolley system, the trolley wire being supported on span wires carried on wood posts. The power is transmitted from the power house at 10,000 volts (alternating three phase) which is transformed and converted in the sub-stations into a direct current of 550 volts in the trolley wire. The cars have four motors of 50 H.P. each and seat 50 passengers. The wheels have cast iron centres and steel tires with ^-inch flanges and 3-inch treads, the small flange being necessary to permit of the cars running over the street railways in Albany and Schenectady. The line cost 30,000 dollars per mile of double track, including equipment. The one objectionable feature of the railway is that it is laid on the public highway, and it is satisfactory to learn that the present tendency in America is to lay high speed lines of this class on land acquired for the purpose. The cars are equipped with the Westinghouse direct air brake, the air reservoirs below the cars being charged at the sub-stations. The works of the General Electric Company at Schenectady are very extensive, and equipped with all the most modern plant. They employ about 9,000 hands. The Company are giving particular attention to the development of the Curtis steam turbine, which differs in detail, though not in principle, from the Parson's turbine. The blades of the Curtis turbine are somewhat longer and thicker than those of the other, and are cut out of the solid steel disc, instead of being built on to the latter. I saw some most ingenious automatic tools at work, which have been devised for the purpose of cutting and shaping the blades. This method of construction seems to possess greater strength and durability than the other, but is probably more costly, though I have no figures as to this. Another peculiarity of the Curtis turbine, as manufactured by the General Electric Company for use with electric generators, is that it is fixed upon a vertical shaft, the turbine being below and the generator above, the weight of the shaft and of the machinery attached to it being supported upon oil, which is forced in under pressure below the end of the shaft, so that the latter revolves upon a film of oil. This arrangement of the machine economises space and makes the whole thing remarkably compact. The party returned to Albany at 6 p.m., and was entertained at dinner by Mr. Coffin, president of the General Electric Company, who came from New York for this purpose. Saturday, October \8th. The car was attached to the train for Buffalo, leaving Albany at 8.15 a.m., and after a pleasant journey on the New York Central Railroad \ve arrived at Buffalo at 4 p.m., where we were met by Mr. Fisher, the superintendent of the Toronto, Hamilton, and Buffalo Railway. After a drive round Buffalo, the party was entertained at dinner at the Buffalo Club. After dinner I went to the power station at the Buffalo Electric Lighting and Power Company, where current is received from the Cataract Power and Condiiit Company, a sub-company of the Niagara Falls Power Company, at 11,000 volts (three phase alternating) and is transformed or converted into currents of less voltage (alternating or direct) according to the needs of the various consumers. This is a most interesting place, the transformers and converters being very numerous, and only requiring two men to look after them. Sunday October 12th. The party went by train at 10 a.m. to Niagara, and after inspecting the low pressure pneumatic interlocking and signalling plant in the signal cabin at Suspension Bridge we went to the power house of the Niagara Falls Power Company and saw the celebrated turbines, &c. We were conducted 37 over the power station by some of the officers of the Company, and were given every opportunity of seeing all there is. Under its charter the Company has the right to take 200,000 H.P. from the falls. At present only one power station is at work with a capacity of 50,000 H.P., but a second station is nearly completed of the same capacity, both these being supplied with water by the same canal. The difference of level between the water in the river lj miles above the falls and the river below the falls is about 200 ft. The power station is situated 1 J miles above the falls, and is connected with the river by a canal 250 ft. wide, 12 ft. deep, and 1,700 ft. long. Parallel with this is a wheel pit 425 ft. long, 18 5 ft. wide, and 178'5 ft. deep. From the wheel pit a tunnel 6,890 ft. long, 18 ft. 10 in. wide, and 21 ft. high is constructed under the town of Niagara, and discharges into the river below the falls. It is of horse-shoe form through- out, is lined with brickwork, and at its lower end is plated with steel. In the sides of the canal are openings guarded by gratings, and from these steel penstocks 7 '5 ft. in diameter conduct the water to the turbines in the wheel pit below. The turbines, of which there are ten now at work, are twin wheels, inverted, that is to say, the water enters them below and comes out above, and they work under a head of 136 ft. Each turbine has a capacity of 5, COO H.P. From the turbines hollow vertical shafts extend upwards to the generators above, which revolve at 250 revolutions per minute. The generators are two phase alternating current machines with revolving fields and fixed armatures, producing current at 2,200 volts pressure. A portion of this current is then transformed to 22,000 volts for transmission to Buffalo, the remainder being transformed to 11,000 volts for transmission to the sub-station two miles away, where it is stepped down for redistribution to the local factories. The most distant sub-station in Buffalo is 31'4 miles from the falls. The whole district between Niagai^a and Buffalo is being covered with manufactories, and there is little doubt that in a few years' time the two cities will become very important industrial centres. On the Canadian side of the river the Canadian Niagara Power Company are now installing a plant of 100,000 H.P., and a third company, the Ontario Power Company, are also commencing work upon a similar station. In the afternoon we visited the falls, and saw them from every point of view, a car of the International (Electric) Railway Company being placed at our disposal by the manager of the Company, who made every arrangement for our convenience. This railway is a combination of several different lines, including the one on the Canadian side of the falls and rapids. It has a total mileage of about 200 miles of double track. It commences in Buffalo, whence two main routes diverge, one a high speed line to Lockport and Olcott, on Lake Ontario, and the other to Niagara. The latter line crosses the river just below the falls by the steel arched bridge belonging to the Company, and recrosses it some distance below the whirlpool and rapids by the new suspension bridge recently erected, whence it returns to Niagara and Buffalo along the American side of the river. We then returned to Buffalo by way of the Buffalo and Lockport line, which we joined at Tonawancla Junction, about half-way between Niagara and Buffalo. This is a high speed single track trolley line, between Buffalo and Lockport, with an extension to Olcott, the total mileage being about 35. The schedule speed on it is 27 miles per hour outside the city limits, and the maximum speed is 50 miles per hour. The round trip fare from Buffalo to Lockport and back is 75 cents. The cars have four 50 H.P. motors, and weigh 22 tons. Two 30 ton electric locomotives are also used upon this line to handle the freight service. These are capable of drawing trains of 650 tons at the speed of 10 miles an hour, and trains of 450 tons at 15 miles per hour. The locomotives have four motors of 165 H.P. each, making a total of 6, Buffalo 16*, 37 > Detroit 16,39 > Chicago 16,4:0 Illinois Central Railroad 41 48 PAGE.
