4.5.5 Stopping (using the Independent Brake and Throttle selectors)
To stop the train manually using the Independent Brake selector:

to a manually controlled stop.
• To recover from a Full Brake application

o set Independent Brake selector to RELEASE,
o press RESET and
within two seconds move the Throttle selector out of HALT.
To stop the train automatically using HALT:
• Turn the Throttle selector to 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. Recover from Full Brake application same as above.
4.5.6 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.
• 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.
• 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.
• When the Automatic Brake selector is pressed for apply for more than two (2) seconds full
service trainline brakes are commanded.
4.5.7 Tilt
When communications are active and the OCU is tilted, the audible indicator will sound a fast
beep (critical warning), for about 3 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.
• 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.
• Once cleared, the tilt alarm will stop.
4.5.8 Tilt Extend
The tilt extend is provided to facilitate operator tasks requiring two hands.
To extend the tilt timeout the brakes must be applied.
• Set the Throttle selector to HALT.
• Press the F1 push button on the keypad until the OCU acknowledges the request with
a double beep then release F1.
• The operator has 60 seconds to perform tasks while tilting the OCU.
• The Tilt Extend is canceled when the operator commands a brake release.
