When may a train make an unscheduled stop?

A train may make an unscheduled stop with authorization from the dispatcher because this process is part of the operational protocols established for safety and efficiency. Dispatchers have a comprehensive view of the entire rail system and manage train movements based on real-time conditions, track availability, and safety considerations. By requiring authorization, the system ensures that all unscheduled stops are coordinated and do not disrupt the overall schedule or pose safety risks to the train or its passengers. This controlled approach helps maintain order and effective communication within the railway operations.

In contrast, making unscheduled stops only in emergencies would restrict necessary operational flexibility, while allowing stops at any location requested by passengers could lead to potential safety issues or disruptions. Additionally, permitting whenever deemed necessary by the conductor might lead to inconsistent decision-making without the broader operational oversight that a dispatcher provides.
