What should a crew do when they observe a track obstruction or defective signal within their warrant?

• A. Stop short of the obstruction, apply the applicable safety procedures, and inform the dispatcher immediately.
• B. Ignore it and continue.
• C. Wait for a supervisor to arrive.
• D. Notify passengers.

Answer: (C)

When you’re operating under a track warrant and you encounter an obstruction or a defective signal, the priority is immediate safety and coordination with the railroad’s control authority. The correct action is to stop before the obstruction, put the proper safety protections in place, and inform the dispatcher right away. This ensures the track is protected from other movements, the obstruction or defect can be assessed and addressed, and movement can be authorized or rerouted by the dispatcher in a controlled way. Waiting for a supervisor, ignoring the obstruction, or trying to notify passengers doesn’t provide the necessary protection or authority to proceed safely. The dispatcher coordinates the next steps, including restrictions or clearance, so you can move only when it’s safe and authorized.
