Hydra-Mechanical shutoff. Pull out red knob and hold until engine stops.
Air inlet shutoff knob. Set knob to STOP.
2-18. COUPLING TO TRAIN AND PUMPING UP AIR
Closely observe brakeman's signal. Failure to do so
may result in injury or death to personnel.
Coupling speed should not exceed 2 mph (3 km/h)
or damage to the locomotive and cars may result.
Stop a safe distance from the head car or other unit until it is determined that knuckles are open and couplers are
properly alined. Ensure trainline hoses are in proper position. Advance slowly to couple train.
After coupling to train, stretch coupling to ensure that couplers are locked.
Couple train line air hose and open angle cock
When the train's air system has not been
charged by a yard line and the main reservoir
pressure falls below 120 psi (827 kPa), cut in
the brakes as follows:
Move throttle (1) to IDLE.
Move reverser (2) to NEUTRAL position
(3) Advance throttle (1) slowly (not to exceed position #4) until the required pumping rate is reached; as main
reservoir pressure builds up, reduce the throttle.
Perform train airbrake terminal test in accordance with paragraph 2-13c.
2-19. UNCOUPLING PROCEDURES.
Move automatic brake valve to make a minimum of 20 psi (138 kPa) brake pipe reduction to ensure brakes are
Signal brakeman to turn cutout cock on trainline hose to CLOSE.
Signal brakeman to lift cutter lever and ensure coupler pin is disconnected.
To prevent injury, ensure brakeman is away from
trainline hoses before moving locomotive.
Proceed forward or backward slowly and ensure coupler and trainline hoses disconnect properly.
