Stopping and Changing Directions
To stop the train manually using the Independent Brake selector:
¾ Rotate the Throttle selector to IDLE
¾ Rotate the Independent brake selector to apply the required braking power to bring the
train to a manually controlled stop.
¾ Once the train is stopped a new direction can be selected using the reverser toggle
switch.
To stop the train automatically using HALT:
¾ Turn the Throttle selector to HALT and wait three (3) seconds for the HALT timeout
indicated by a single OCU beep. The RCU will automatically apply a controlled
application of independent brake.
¾ To recover from a Full Brake application
o set Independent Brake selector to RELEASE,
o press RESET and
within three (3) seconds move the Throttle selector out of HALT.
Note: This is a more aggressive controlled stop where the Train Chief® II system applies a
ramped application of independent brake until a full-application locomotive stop is achieved.
Trainline Brake Operation (when equipped)
When the Train Chief® II system is equipped with optional trainline brake control the Automatic
Brake selector on the OCU will be used to apply and release train brakes.
¾ The Automatic Brake release is selected when the toggle is pulled toward the operator
o The receiver / controller commands full air pressure to the brake pipe which places
the train brakes in a fully released state.
¾ The trainline brakes are progressively applied each time the trainline brake switch is
momentarily pressed away from the operator.
o When the switch returns to center the last commanded pressure is maintained.
o If desired, Bail off independent brakes by pressing the Bail function switch.
¾ When the Automatic Brake selector is pressed for apply for more than two (2) seconds
full service trainline brakes are commanded.
Tilt
When communications are active and the OCU is tilted, the audible indicator will sound a
continuous beep (critical warning) for about 2 seconds before commanding an emergency
locomotive stop.
Once the emergency locomotive stop command is sent, the alarm no longer sounds
continuously, but will sound once every 3 seconds to indicate that the locomotive emergency
stop command continues to be sent.
¾ This condition continues as long as the OCU remains tilted.
The tilt condition is cleared when the OCU is returned to its upright position, or when power is
turned off, or when the battery becomes fully discharged.
¾ Once cleared, the tilt alarm will stop.
