2-24. GROUND RELAY ACTION (cont)
b.
When the ground relay trips, correct the trouble
as follows:
(1)
The ground relay may be energized by
some temporary condition. Reset by
returning throttle (1) to IDLE position and
pressing GROUND RESET pushbutton
(2). Normal operation may then be
resumed.
(2)
If the ground persists, stop engine and
report this condition to your supervisor.
2-25. RUNNING OVER RAILROAD INTERLOCKINGS
When running over interlockings, move the throttle handle to reduce speed and avoid excessive jarring of gears and
electrical pitting of commutators.
2-26. EMERGENCY APPLICATION OF BRAKES
a.
When the brakes apply automatically from the
train at an emergency rate of reduction
(indicated by the brake pipe pressure falling
rapidly to zero), place automatic brake valve
handle (1) in EMERGENCY position to prevent
the escape of main reservoir pressure, and
leave it in that position until train stops. Move
throttle handle (2) to IDLE position. Push sand
control (3) until train stops.
b.
Use independent brake valve (4) to reduce
brake cylinder pressure on the locomotive to
prevent sliding the wheels. Then use the
independent brake heavily for the last 100 feet
(30.48 m) to avoid a runout of slack as the train
stops.
