2-26. EMERGENCY APPLICATION OF BRAKES (cont)
c.
After stopping, wait 2 minutes, then place automatic brake valve (1) in RELEASE position for at least 30
seconds, then move to SUPPRESSION.
d.
Brake pipe pressure falling to ZERO indicates an air hose is parted or a brake pipe is broken. In either case,
move automatic brake valve (1) to RELEASE position to provide pressure for trainman to locate the defect. If
brake pipe is not broken or hose parted, leave automatic brake valve in RELEASE position to release brakes.
2-27. BRAKING WITH POWER
When braking with power, drawbar pull rapidly increases as the speed decreases for any given throttle handle position.
This pull may be great enough to part the train unless the throttle handle is reduced as the train loses speed. The load
meter indicates the pull of the locomotive. A constant pull can be maintained on the train during a slowdown if a steady
amperage is kept on the load meter by consecutively reducing the throttle handle a notch whenever the amperage starts
to increase. Keep the independent brake fully released during power braking. The throttle handle must be in IDLE
position before the locomotive comes to a stop.
2-28. EMERGENCY STOP CAUTION
CAUTION
Before resuming operation after
an emergency brake application,
inspect equipment for possible
damage. Make sure all brakes
apply and release properly.
To stop the train in the shortest possible time (to save
life or avoid an accident), move automatic brake valve
handle (1) quickly to the EMERGENCY position or trip
emergency brake valve (2), and move throttle handle
(3) to IDLE position.
