If a lock is defective or missing on a main track switch or a derail that protects the main track, you must:

• A. Report the missing or defective lock to the train dispatcher and be governed by his/her instructions
• B. Continue operating as normal
• C. Replace the lock yourself
• D. Notify supervisor only

Answer: (A)

When a main-track switch or derail protection is missing or defective, the route is not safeguarded and could be misaligned or left unprotected. The proper action is to report the missing or defective lock to the train dispatcher and follow their instructions. The dispatcher has the authority to provide movement and protection guidance, halt or authorize trains, and arrange repairs or temporary protections. Continuing to operate without dispatcher clearance would bypass safety safeguards, and replacing the lock yourself is not an appropriate or authorized action. Merely notifying a supervisor isn’t enough, since the dispatcher controls track authority and movement on the line.
