If radio communication with the dispatcher is down, which steps should you take?

• A. Use contingency procedures, attempt other communications, and notify supervisor.
• B. Continue as if the radio works.
• C. Shout for help across the car.
• D. Wait until someone notices.

Answer: (D)

When radio contact with the dispatcher is lost, immediately switch to contingency procedures and use any available alternate communications, then notify a supervisor so operations stay coordinated. This ensures someone at the control center knows your status, location, and can issue new instructions to keep trains and crews safe. Contingency procedures are built for exactly this situation and typically involve using trackside phones or other radio channels, and reporting your status through the approved method. Notifying your supervisor promptly helps coordinate a safe flow of traffic and prevents trains from proceeding without guidance. Shouting for help or continuing as if the radio works aren’t reliable or approved methods and can create confusion or unsafe conditions. Waiting until someone notices is similarly dangerous because you may be unaware of how your move could affect other trains, signals, or your own crew.
