How does the dispatcher provide permission to use the Stop Release Function?

The dispatcher provides permission to use the Stop Release Function by confirming the information relay. This process is crucial for ensuring safety and accuracy in train operations. Confirming the information relay indicates that the dispatcher has verified the relevant details regarding the train's status, location, and any conditions that need to be considered before granting permission. This confirmation helps to prevent misunderstandings or errors that could occur if information was not fully verified, thereby maintaining operational integrity.

In contrast, options that suggest a written document, verbal instructions only, or a visual signal may not adequately capture the comprehensive nature of the communication and verification process required in such situations. Effective dispatching relies heavily on accurate and confirmed information, emphasizing the importance of proper relay confirmation as a critical step in the procedure.
