4 START UP AND OPERATING PROCEDURES
Locomotive Stops
The locomotive remote control system can automatically initiate either of two (2) types of
locomotive stops, depending on the specific situation. The two locomotive stops are defined
below and are referenced in subsequent operational descriptions.
Full-Application Locomotive Stop - The full-application locomotive stop is automatically
initiated in certain situations that are deemed non-emergency. This type of locomotive stop
requires a reset of the OCU to resume normal operation. The full-application locomotive stop
automatically initiates the following actions;
¾ full application of independent (locomotive) brakes
¾ full application of trainline brakes (when present)
¾ locomotive throttle to idle
¾ disengagement of generator field
Emergency Locomotive Stop - The emergency locomotive stop is automatically initiated in
certain situations (including the E-Stop command) that are deemed an emergency. This type of
locomotive stop will require specific intervention in order to resume normal operation. The
emergency locomotive stop automatically initiates the following actions;
¾ emergency applications of independent (locomotive) brakes
¾ emergency application of trainline brakes (when present)
¾ locomotive throttle to idle
¾ disengagement of generator field
¾ After any emergency locomotive stop, the operator may not be able to restart the system
from the remote OCU (or remote control station) because the locomotive will be in a
Power Cut-off Switch (PCS) fault condition. To recover from this condition the operator
may need to go to the locomotive cab to reset the PCS fault. PCS fault reset procedures
will be dependant and specific to the locomotive.
Locomotive PCS Fault – The locomotive PCS fault is a latching condition that may occur on
the locomotive that will prevent locomotive operation. This fault may occur whenever there is an
emergency application of trainline brakes, based on a locomotive pressure switch that monitors
the trainline brake air pressure.
¾ The emergency application of trainline brakes will occur whenever the remote control
system commands an emergency locomotive stop, forcing the PCS fault condition. This
will happen whenever;
o an E-Stop button is pressed
o the OCU tilt (man down) feature is triggered
¾ Depending on the locomotive and whether it is in manual control or remote
control mode, the procedure to reset a PCS fault may be different. It is the
responsibility of the operator to understand the specific locomotive PCS fault
reset procedures required.
