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

• A. Ignore and continue
• B. Report the device to Trainmaster/Dispatcher and follow their instructions
• C. Replace the lock yourself
• D. Notify a supervisor

Answer: (B)

When a lock on a main line switch is missing, the switch is considered unsecured and could allow an incorrect or unsafe track movement. The proper action is to pause operations and report the situation to the Trainmaster/Dispatcher and then follow their instructions. The dispatcher controls movement authority, can arrange temporary protection or hold trains as needed, and will coordinate with maintenance to secure or replace the lock. You should not operate the switch or attempt to replace the lock yourself, as that could create further risk. Notifying a supervisor may happen, but the dispatcher is the official point of contact for mainline safety and movement instructions.
