After a train stops at a platform, what is the purpose of the door safety check?

• A. Doors closed and ready for departure.
• B. Doors locked for security.
• C. Seating assignments.
• D. Check ticket revenue.

Answer: (A)

The main idea here is safety and readiness to move. After the train pulls into a platform, a quick door safety check is done to confirm every door is fully closed and secured so the train can depart without the doors opening during motion. This ensures there’s no obstruction in the doorway, nothing can catch or pinch passengers, and the doors won’t unexpectedly reopen as the train leaves. It’s all about making sure the doors are in the correct closed state and the train is safe to move, not about seating, revenue, or security checks.
