Answer: Brake pipe blockage
Feedback:
The system will report a train check failure by showing Train Check Fail and sounding three chimes. The most common causes of a train check fail are: - Blocked brake pipe - Brake pipe leakage - Communication interruption between the lead and remote units If the first train check results in failure, perform a second train check. If the train check fails a second time, use the alternative method outlined in ABTH 105.5.2 B.
