Why is it advised to discharge passengers at the next station under specific conditions?

Discharging passengers at the next station under specific conditions can be primarily advised to ensure passenger safety. If a train encounters a situation that compromises the safety of those on board—such as mechanical failure, severe weather, or other emergencies—evacuating passengers at the nearest station becomes a priority. This action not only secures the well-being of passengers but also facilitates a quicker response from emergency services, if needed.

While it might seem that carrying passengers in such conditions could lead to delays, the foremost concern in such circumstances is the immediate safety of individuals. Thus, prioritizing disembarkation ensures that passengers can be managed effectively and safely, while maintaining a focus on overall safety protocols. The other options, such as reducing weight or adhering to a schedule, are secondary considerations in the context of passenger safety during emergencies.
