10 INSTRUCTIONS FOR MECHANICAL AND ELECTRICAL SECTIONS.

When printed inspection forms pro\ided for the use of the field parties contain spaces
for record of condition, these forms shall be followed as indicating the data required.
When such forms are not provided, the condition data recorded shall in general con-
form to the following outline, in so far as the nature of the property and the information
permit:

(a) Age.

Ascertain, where practicable, year of construction, installation, or purchase of the

prior to its present service, give such facts as may be obtained as to length and nature
of service elsewhere. State source of data.
(6) Wear and decay.

Record such facts as to wear and decay as may be practicable from field observation.

Record whether maintenance is normal; that is, if the standard of maintenance pre-
vailing is such as to secure the average service life out of the property. If the main-
tenance is above or below normal, gr\e facts on which conclusion is based. Where
extenshe or unusual repairs are needed to put property in serviceable condition,

inspection forms or on the standard loose-leaf notebook sheets prescribed for the pur-
pose, and shall show the property classified by accounts.

The carrier's representative, if present when the original notes were taken, shall
be a party to any changes or corrections made in them, when such changes are made
in the field. In case of such changes or corrections no erasure shall be made of the
original notes, but diagonal lines shall be drawn through the incorrect notes and the
corrected notes inserted. Such changes or corrections shall be made in identical
form on both original and carbon copies and shall be dated and authenticated by the
person making the same.

With each volume of note sheets there shall be a title page which shall show: The
name of the owner of the property; the name of the chief of party in charge, the kind
of party, the kind of property to which the notes relate; and, in the case of fixed prop-

12 INSTRUCTIONS FOE MECHANICAL AND ELECTRICAL SECTIONS.

Property belonging under accounts 26 and 27 should be recorded only as to number
of wires and other attachments, leaving details to be obtained by the parties concerned
with those specialties.

Where poles carry wires or attachments of other companies this fact shall be re-
corded, and generally the number of cross arms or other attachments belonging to
such companies should be noted, as also the points of beginning and ending of such
joint use of pole line. In all such cases inquiry shall be made as to the existence of
joint ownership, and the ascertained facts recorded.

Ascertain all wire sizes. The carrier's records should be verified at convenient
opportunities. Character of insulation and material of wire shall be recorded.

The electrical party shall compute and enter on their field notes the length of each
kind and size of wire, using for this purpose, when available, distances obtained by
the roadway parties. Where the wire lines follow a course not measured by the road-
way party, and no other accurate data is available, the electrical party shall measure
the distances; however, distances given in the carrier's schedule or furnished from
other records of the carrier may be accepted upon sufficient verification.

(d) Overhead trolley constructions.

Stationary structures for supporting trolley wire, including brackets and overhead
bridges, belong under account 33, Power line poles and fixtures. Flexible attach-
ments, such as span wires, catenary cables, guard wires, and the trolly wire belong
uader account 32. Insulators generally belong under account 32, but strain insu-
lators in guys which support poles belong under account 33, and insulators supporting

of track, also similar data for cross bonds, supplementary return, special bonding
at track switches, etc. This information shall be checked by the electrical party to
a sufficient extent to satisfy them of its accuracy, and to form a basis for estimating
condition.

(g) Third rail.

The roadway parties will record the station and plus of beginning and ending of each
third-rail section, and mark the same on the web of the adjacent track rail. All other
inventorying of third rail shall be done by the electrical parties.

Total length of third rail.

Dimensions and weight of joints and number per mile.

Insulator description and number per mile, with manufacturer and catalogue
number if possible.

with sketches if necessary, and manufacturer's designation, if any.

Cable racks and barriers in manholes come under account 34, Underground conduits.

Subject to proper verification, the carrier's records should be made the basis for the
inventory of all this class of property, but sufficient inspection must be done to verify
the carrier's inventories and form a basis for estimating condition.
