How is a train verbally authorized to pass a signal displaying Stop indication?

A train is verbally authorized to pass a signal displaying a Stop indication with a specific message that includes the location of the signal. This procedure is critical for maintaining safety and operational integrity on the railway system. The specific message serves to clarify the location and context, ensuring that all parties involved have a clear understanding of the situation.

When a dispatcher or authorized personnel communicates this message, it establishes a formal and precise directive for the train crew, which is essential to avoid confusion or miscommunication. The authorized passage is typically backed by operational protocols that dictate how such communications should be handled, ensuring that safety measures remain intact while allowing for necessary operational flexibility, such as addressing emergencies or managing train delays.

In contrast, other methods are not typically valid or sufficient for authorizing a train to pass a Stop signal. Reliance on permission from nearby trains does not provide a clear or secure directive and could lead to misunderstanding. Completing a stop at the signal is a necessary action but does not constitute authorization on its own. Automated dispatching systems may provide guidance and data, but they cannot solely authorize a train to pass a Stop signal without a clear and specific verbal communication.
