GN Electric Operations continued

If power is knocked off line by your engine due to any
cause, such as raising a pantograph while a ground switch
is closed, a flashed over insulator on roof, or any high tension
circuit trouble on locomotive roof, notify dispatcher
immediately so line crew will not be called out to look for
trouble that does not exist, as they may really be needed
elsewhere. If you lose trolley power anytime while your
electric locomotive is running or standing anywhere, re-
port it to dispatcher, and if your locomotive is okay let
him know, as trouble could be on the line itself; or on
any motor connected to line.

Special Safety Precautions

General Electric High Tension Bus Connectors

Keep off all locomotive roofs unless all pantographs on
coupled cabs are down and ground switches closed.

General Electric cabs are equipped with an automatic
high voltage connector between cab roofs. This will
perform the same function as the Westinghouse high
tension jumper between cabs, only there will be no danger
of tearing it off when cabs are uncoupled, as it will
be a shoe contact on the end of a rod operated by air
cylinder and piston action. The main idea is be careful when
two or more cabs are coupled together. Never go up on
or near roof of any cab, even with all its pantographs down
unless all other coupled cabs' pantographs are down and
all ground switches closed.

SAFETY FIRST: Never work on the circuits of any
cab in shop, or on line, unless GROUND SWITCHES
are closed, because another cab may be running and someone
working on the air hose between cabs, accidentally may
cut in the high voltage bus connectors, energizing the
transformer of supposedly dead cab. Hence the blanket safety
rule is: Ground switches must be closed on all cabs,
regardless of location, before anyone does work on electrical
circuits. Failure to observe this may cost you your life,
and will result in dismissal from service in any event. It is
up to each individual to fully protect himself and also watch
out not to do anything dangerous to others. With high voltage,
your first is usually your last mistake. Never take anything
for granted. Look and be sure pantographs are
down, and ground switches closed. Finally, never reach
up on roof anytime from any place to fix bell, headlight,
etc. Follow safety rule 100%, then you are safe to work
anywhere around locomotive.

SAFETY ALWAYS: Lower all pantographs, close all
ground switches and be careful anytime you go up on

General Electric and Westinghouse High Tension Bus Line
on Locomotive Roof

The high tension 11,000 volt bus line on locomotive roof
extends between No. 1 and No. 2 pantographs. Its main
duty is to convey power from No. 1 pantograph to locomotive
transformer. In case this bus line gets grounded
or shorted inside of its conduit, both ends of bus line must
be disconnected from other live circuits. Hence, in any case
of bus line failure, No. 1 pantograph is out of service and
must be lowered. Run on No. 2 pantograph.

The bus line connections are as follows: On General
Electric cabs 5010, 5011, 5012 and 5013, bus is located on
left side of roof and the 5014, 5015, 5016 and 5017 bus is
located on right side of roof, and runs from No. 1 pantograph
back to three way connector plate near No. 2 pantograph.
In case of bus failure, disconnect at three way
connector plate and at No. 1 pantograph. In all cases you
will run on No. 2 pantograph when roof bus is disconnected,
so lower No. 1 pantograph, as it is out of circuit.

Westinghouse High Tension 11,000 Volt Roof Bus, Located
on Left Side of Cab Roof

Westinghouse cabs 5004 and 5006: Roof bus is connected
to No. 1 pantograph on one end, and to the connector plate
near No. 2 pantograph on other end. In case of bus failure,
both of these end connections must be broken, and cab
operated on No. 2 pantograph, lowering No. 1 pantograph,
as it is out of service with the roof bus.

Westinghouse cabs 5000, 5001, 5002, 5003, 5008-A and
5008-B: Roof bus is same as other Westinghouse cabs, except
it extends between a connector plate near No. 1 pantograph
to the No. 2 pantograph connector plate, and in case
of failure, both of these connections must be broken and
cab run on No. 2 pantograph.

Failure of any 11,000 volt equipment makes itself known
by trolley power kick-off, and plenty fireworks on roof,
usually burning holes in conduit, etc., or shattering roof

Special Note: If the insulators supporting round copper
roof bus that runs from No. 2 connector plate up to high
tension jumper between cabs should fail, remove the jumper
between cabs, then remove copper bus, and run engine

with pantographs up on each cab. Any broken insulator
will tie up the circuit it is in.

Starting Up Dead General Electric Motor Generator Set


(A) Raise pantographs as covered by instructions.
Transformer fans immediately start.

(B) Pump up main and control reservoirs as covered
by Compressor Instructions.

(C) Be sure that ground relay, trolley relay and motor
generator overspeed relay are closed and that thirty
ampere auxiliary control fuses are 0. K., (they are if
headlights burn), and ten ampere carbon pile fuse is also okay.
Note: If relay PR3 closes, carbon pile fuse is okay.
To start M-G set, be sure switch control air is 70 lbs.

(1) Place control key in M-G start button switch: and
shove key to left to release switch lock bar.

(2) Push in M-G start button. Set will begin accelerating
and in about one minute M-G set will be synchronized
at full speed, 750 R. P. M., and voltmeter will show around
2,300 to 2,500 volts. Switches 4, 8, 9, 10 are closed.

(3) Check oil rings on all M-G bearings, and be sure
they are all turning.

(4) Remove control key from M-G start switch and place
it in top of auxiliary button switch station, then push it
ahead to unlock button switches.

(5) Start traction motor blower.

(6) Close controller switch on ceiling above engineer's
head. Be sure its thirty ampere fuse is okay. Controller.
fuse is okay when by taking one notch on speed lever,
and then opening controller switch, a flash is seen at
switch contacts.

Note: Be sure roundhouse switch is closed in up, or road
position, and all traction motor cut out switches closed.

(7) To close JR breakers, push in JR hold button and
leave it in.

(8) Push in JR reset button and hold it in about five
or ten seconds to give operating cylinders a chance to fill
with air and close breakers. Set engine brake.

(9) Throw reverse lever forward. Take one notch on
speed controller. D. C. armature amperes should read 150
or 200.

Page 15

(10) Shut off controller, reverse engine and notch one on
speed. D. C. armature amperes should read same as before.

(11) Shut off controller, pull field lever open to "E"
notch, pull speed lever open one notch, then pull field lever
wide open. Field amperes should read 400 to 600 D. C.
Shut off both levers, reverse engine, repeat same test.

Note: Test No. 11 shows that all traction motor cut out
switches are closed. Tests Nos. 9 and 10 show that roundhouse
switch is closed properly in the up position for road.

(12) Be sure transformer fans and traction blowers are
running and band brake released. Engine is now ready for

Shutting Down General Electric Locomotive

To shut down a General Electric motor generator set:

(1) Push any red stop button, or the stop button under
M-G start switch. There is also a multiple M-G stop button
on auxiliary button switch board at engineer's right
hand, which will shut down all General Electric cabs connected

(2) Lower pantographs per instructions.

(3) Open battery switches all cabs.

(4) Set hand brake.

(5) Close all doors and windows, and in cold weather
drain all reservoirs.

Engine is now tied up properly.

General Electric or Westinghouse Crews On All Electric Locomotives

Special Note: If M-G sets are ordered shut down on
road, or at helper terminal in winter time, to have cab
heaters working, pantographs may be left up. Exceptions
are no electric locomotive will be left standing with
pantographs up, even when M-G is shut down, unless someone
is aboard locomotive, as a flashed over insulator on
locomotive could tie up system with no one around to lower
pantographs if something should let go on roof.

General Electric Locomotives

Compressors: Note: General Electric compressors have
two individual fuses located in No. 2 switch chamber. To
cut out a compressor for any cause, remove its fuse.
SAFETY ALWAYS. Be sure pantographs are down and
ground switches closed.
