Which statement is false regarding passenger safety on trains?

The statement about it being permissible to leave doors open if they are away from the platform is false because it poses a significant safety risk. In train operations, doors should remain closed during transit to prevent accidents or unintended exits. Keeping doors open, regardless of their position relative to the platform, can expose passengers to danger, especially if the train is moving or if there is a sudden stop.

Maintaining a secure environment is critical for passenger safety, which is why the other statements reflect safety protocols. For instance, it is standard procedure to prevent passengers from occupying the vestibule while the train is in motion to avoid injury in case of sudden stops or movements. Wheelchairs are typically not permitted in the aisle to ensure that passageways remain clear for emergency situations and to allow for the safe movement of other passengers. The requirement to keep the door closed between the coach and vestibule further enhances safety by preventing passengers from inadvertently falling out of the train or being exposed to the tracks.
