What must a Dispatcher determine before changing a train's route during an emergency?

Before changing a train's route during an emergency, it is crucial for a Dispatcher to determine that the train has stopped. This is critical because a moving train cannot be safely redirected to a new route without significant risk. Ensuring that the train has come to a complete stop allows the Dispatcher to evaluate the situation more effectively and reduces the potential for accidents, miscommunication, or further complications in the emergency.

In an emergency scenario, it is essential to prioritize the safety of all individuals involved, including passengers and crew. The Dispatcher needs to have confirmation that the train is not in motion so that any further actions, such as rerouting, can be executed without endangering lives or causing additional hazards on the track. The responsibility of the Dispatcher includes making informed and safe decisions, which is why knowing the status of the train is a foundational step before considering any route changes.
