2-20. CUTTING OFF LOCOMOTIVE WITH OR WITHOUT CARS
a.
When the locomotive is to be cut off or the train is to be separated, leave the brakes applied with a full service
application.
b.
On completion of the full service reduction, give one short blast of the whistle to inform the trainmen they may
close the angle cocks and cut off the locomotive or cars. This is very important to prevent brakes from sticking
at the rear of train and to prevent cars from moving on grades.
2-21. STARTING TRAIN. Starting a train depends on the grade, weather condition, type, length, weight, and amount of
slack. Make a brake test (para 2-13) to determine if all brakes are functioning properly in the SERVICE and RELEASE
positions and that no handbrakes are set prior to starting.
2-22. WHEEL SLIPPING
CAUTION
If slipping occurs, reduce throttle
first. Never apply sand while the
wheels are slipping, as this could
cause a broken traction motor
gear.
a.
If SLIP indicating light (1) flashes, one or more
pairs of wheels are slipping. Reduce throttle (2)
until light extinguishes. Apply sand with sand
lever (3) and slowly open the throttle.
b.
Under
extreme
rail
conditions
(excessive
grades, rain, ice, or snow) repeated slipping
may occur. In these instances, reduce throttle
(2) to apply maximum power without causing
wheel slippage.
