Air Brakes and Safety Features Test
According to the FRA Safety Advisory 2001-01 it is recommended that the air brake and safety
function of the OCU be tested at the beginning of any remote control activity. The following
summary is provided in support of that practice.
Locomotive Brake Test. Perform all required standard locomotive and trainline brake tests
using the OCU to ensure all remote braking functionality.
E-Stop Test. Perform an E-Stop from the OCU to verify remote activation of the emergency
locomotive stop. Also test all other locomotive mounted E-Stop push buttons associated with
the remote control system.
Tilt Test. To test the Tilt feature of the OCU, tilt the OCU more than 45-degress. The OCU is
operating properly when:
¾ A continuous tone begins within approximately three (3) seconds
¾ Then a Tilt Time Out occurs after approximately two (2) seconds of tone
¾ The RCU responds by commanding an Emergency Locomotive Stop
To recover from a Tilt Time Out Fault, return the OCU to normal operation position.
Local Man-Down Alarm Test. To test the local man down alarm, maintain the OCU in a tilted
position while in an active tilt alarm condition. After a period of not greater than 90-seconds and
not less than 60-seconds the locomotive horn shall sound at an alternating rate of one second.
The locomotive horn will continue to sound the man down alarm until the system is reset.
Remote Man-Down Alarm Test (if present). If your system is equipped with the optional
remote man down feature, the remote man down alarm is triggered when the local man down
alarm is activated. Refer to the system configuration documents for your specific operational
detail.
Alert Test
To test the Alert feature of the OCU
¾ Place the Reverser selector in Neutral
¾ Place Independent Brake to Full position
¾ Set Auto Brake to RELEASE (or some application to hold the train in position)
¾ Set Throttle selector out of HALT
¾ Wait for approximately 50 seconds
The OCU is operating properly when
¾ A fast rate pulse tone begins after approximately 50 seconds
¾ Then after approximately 10 seconds an Alert Time OUT occurs
¾ The RCU responds by commanding Full Service Locomotive and Automatic Brake
Application.
To recover from an Alert Time Out, return the OCU Throttle selector to HALT position.
Initial start-up and safety checks are completed.
The system is ready for operation.
