During what situation is it acceptable for a train to be unboarded?

The scenario in which it is acceptable for a train to be unboarded is during emergency situations. This policy ensures the safety of passengers and crew members. In emergencies, such as mechanical failure, accidents, or severe weather conditions, it may become necessary to evacuate the train to protect individuals from potential harm.

During such events, it is critical that the crew takes the appropriate measures to ensure that all passengers disembark safely and as quickly as possible. This procedure helps in managing the situation effectively and allows for emergency services to respond as needed.

In contrast, being off duty, arriving at the final terminal, or after the scheduled departure time do not typically warrant the directive to unboard passengers, as these situations are planned and should follow standard operational protocols for passenger transit.
