Starting (Train Handling)
¾ Set Movement Direction (FWD or REV)
¾ RELEASE Automatic Brakes by pulling the toggle switch for 1-2 seconds (if equipped).
¾ RELEASE the locomotive brakes:
o Move the Independent Brake selector to RELEASE (rotation toward operator) as
shown by all indicators off.
¾ Press RESET (to reset brakes)
o Throttle selector must be moved from the HALT position within 3 seconds of pressing
the RESET.
¾ Advance the throttle selector to the appropriate throttle position to generate the required
power to slowly accelerate the train.
¾ Use the Automatic or Independent Brake selectors to slow or stop the locomotive.
o Locomotive brakes can also be applied by moving the throttle selector to HALT.
¾ To resume movement (without reverser change):
o Press RESET
o Within two seconds the Throttle selector must be moved out of HALT position or else
the selection will be ignored.
● If ignored, place Throttle to HALT and repeat from RESET.
Note:
Radio Communications – Typically the OCU transmits four messages per second
to the locomotive equipment. If the locomotive does not receive a valid message
within a set timeout period (typ 1.25 sec) a Full Service Brake Application will
occur. During the timeout period the last valid command will prevail.
Alert Operation
The operator alert function is activated when the Throttle selector is moved out of the HALT
position (regardless of the Reverser selection).
If there has not been any function or command switch activity (i.e. periodic pressing of the
RESET switch) for more than 60 seconds then Train Chief® II will automatically initiate the Full-
Application Locomotive Stop command.
o The Alert Timeout warning will cause a fast pulse tone after 50 seconds of command
switch inactivity to alert the operator of an impending Full-Application Locomotive
Stop.
o If the operator responds to the Alert Warning by pressing ANY button within 10
seconds the alarm is cleared.
¾ To recover from an Alert Timeout, return the OCU Throttle selector to HALT position.
¾ The specific time setting for the alert feature may be different, based on specific user
request. Refer to site operating rules.
