General Notice
Every employee whose duties are in any way connected
with the operation and maintenance of the electric
locomotives, is required to be familiar with the apparatus he
is called upon to operate and repair in the performance of
his duties and will be examined from time to time as to his
qualifications for such duties by such persons as are
appointed by proper authority. Engineers and firemen are
required to familiarize themselves with the name and
location of all apparatus. Engineers, in addition to above,
are required to know the principle of operation of the
various pieces of apparatus, the manner in which they should
be operated, and the method of procedure in case of failure.
Inspectors and electricians, in addition to the above, are
required to be familiar with the construction and details of
the apparatus and methods of making repairs.

Qualifying For Electric Service
(a) Engine crews qualifying for electric service, should
primarily be men who are already qualified to railroad in
mountain territory, regardless of what kind of power is
used.
This is merely a safety precaution, as a loss of trolley
power on electrics may mean handling trains on grade
with air brakes.
(b) Engineers and firemen qualifying on electric locomotives
will report to Foreman at Appleyard Electric Shop
for preliminary instructions, which consist of learning the
SAFE methods of starting and shutting down General
Electric and Westinghouse motor generator sets on locomotives,
the locations, positions and functions of relays,
switches and fuses, as well as the proper way to change
out blown fuses, reset tripped relays and to tell by
inspection when a switch or relay is energized and operating
properly.
The location of bearings on motor generator sets,
traction motors, blower motors, compressors, motor
suspension bearings, truck and driver boxes, how to temporarily
fix up bad order ones to get over road, and mainly how to
report properly the location of detective apparatus regardless
of which end you happen to be operating from; the
locations must all be in respect to "F" end as covered in
another part of these instructions.
Both engineers and firemen get the same preliminary
instructions to familiarize them with locomotives. They
will then be instructed in the proper method of lining up
the three way cut out cocks and air brake apparatus on
electrics, which differ somewhat in details from the steam
power on account of double end controls on electrics.
This also will include method of coupling up controls,
air and electric, for multiple unit operation.
Methods of operating the electric cabs in motoring and
regeneration will be taught. Remembering that there are
two different designs of the same type of motor generator
locomotive in service, Westinghouse and General Electric,
and both are alike except for details, men must be familiar
with both locomotives.
(c) Student trips on road with regular crews will follow
the preliminary instructions at shop. Engineers will make
trips on freight, head end and helper, observing how
regular men handle the job; also on through and local
