What is the purpose of a safety check of doors after stopping a train at a platform?

• A. Turn off displays.
• B. Doors are properly closed and the train is secured for departure.
• C. Open the doors for ventilation.
• D. Ignore door status.

Answer: (B)

The main idea is to make sure the vehicle is ready to move safely. After a train stops at a platform, you must verify that every door is fully closed and locked and that the train is secured for departure. This prevents passengers from being exposed to open doors or the door interlock system from failing as the train starts to move, and it ensures the train won’t roll away unintentionally. You’ll check door status indicators and interlocks and confirm the braking or parking brake is set so the train stays in place until you’re ready to depart. Other tasks like turning off displays or opening doors for ventilation don’t protect against movement or door failures, so they aren’t part of the safety check.
