When a lock on a main line switch is missing, which action should you take?

• A. Report the device to Trainmaster/Dispatcher
• B. Replace the lock yourself
• C. Follow the Dispatcher/Trainmaster's instructions and report
• D. Ignore the issue and continue

Answer: (C)

When a main line switch lock is missing, treat it as a safety risk and do not operate or try to fix it yourself. The correct action is to report the issue to the Trainmaster/Dispatcher and follow whatever instructions they give. The dispatcher controls track authority and interlocking safety, so they’ll tell you how to proceed in a coordinated, safe way. Replacing the lock is not appropriate for you to do, and ignoring the issue could lead to an unsafe move of the switch. Reporting promptly allows maintenance or supervision to secure the route and protect personnel and trains.
