What is the correct procedure when a signal failure is 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.
• C. Ignore the signal.
• D. Attempt to fix the signal yourself.

Answer: (D)

When a signal failure is reported, the safe and proper approach is to alert the dispatcher and not proceed beyond the failed signal without explicit authorization, then follow the contingency procedures in place. Treat the situation as an indication that the normal signaling in that area cannot be trusted, so you rely on coordinated instructions from the dispatcher to determine safe routing, speed restrictions, or stops. This keeps you from unknowingly entering an occupied or restricted block and ensures that other trains are accounted for and protected.

Continuing at normal speed ignores the risk that the signal might be red or malfunctioning, which could lead to a collision or derailment. Ignoring the signal altogether is unsafe and could put you and others in danger. Attempting to fix the signal yourself is not within operator duties and could cause further damage or electrical hazard; only qualified maintenance personnel should repair signaling equipment.
