How should a crew handle a signal failure reported by a passenger?

• A. Notify the dispatcher; do not proceed past the failed signal without authorization, and follow contingency procedures.
• B. Continue at normal speed and proceed.
• C. Ignore the report.
• D. Reboot the signal remotely.

Answer: (A)

When a signal failure is reported, safety hinges on getting clear guidance from the dispatcher and not moving past the affected signal without authorization. The crew should immediately inform the dispatcher of the failure and the location, then follow the prescribed contingency procedures. This might mean proceeding only with explicit clearance, or operating under a controlled or restricted movement plan until the issue is resolved. Rebooting the signal remotely isn’t a crew action and requires proper maintenance or control-center procedures, so it isn’t appropriate to attempt. Ignoring the report or continuing at normal speed bypasses the safety safeguards that protect against collisions or misrouting. By coordinating with the dispatcher and adhering to the contingency plan, the train can move safely only when authorized.
