What should you do if radio communication is lost?

• A. Reattempt, switch to backup channel if available, and notify dispatch.
• B. Ignore and proceed.
• C. Shut down immediately.
• D. Signal with hand flags only.

Answer: (A)

When radio communication is lost, the priority is to reestablish contact and maintain safe movement through established authority. Start by reattempting on the same channel to clear a temporary glitch. If that fails, switch to a backup channel if available to reach dispatch and other trains. Then promptly notify dispatch of the loss of contact so they can issue instructions, hold trains if needed, and confirm track occupancy and movement authority. This keeps everyone informed and prevents movements without clearance. Avoid proceeding without contact, and don’t rely solely on hand signals for long-distance coordination.
