What action should be taken if the Stop and Stay function cannot be released?

In situations where the Stop and Stay function cannot be released, notifying the Trainmaster and following their instructions is essential for maintaining safety and operational integrity. The Stop and Stay feature is a critical safety mechanism designed to prevent movement in case of emergencies or system errors. When this function is engaged, it indicates that there is a potentially hazardous condition that requires immediate attention.

By alerting the Trainmaster, you ensure that a qualified individual can assess the situation and take necessary actions, which may include coordinating additional assistance or establishing safe procedures for resolution. This communication is vital because it prevents unauthorized operations and promotes a coordinated approach to address the problem without compromising safety.

In contrast, waiting for signal clearance might not be applicable if the system has malfunctioned, proceeding with caution could lead to unsafe conditions if the underlying issue is not resolved, and continuing to the next station risks endangering the train crew, passengers, and equipment. Therefore, following protocol and including the Trainmaster in resolving the situation is the most responsible and safe course of action.
