In the event of a malfunctioning stop signal, what is the appropriate action for an engineer?

In the event of a malfunctioning stop signal, contacting dispatch for further instructions is the appropriate action for an engineer. This ensures that the engineer communicates the situation to the relevant authority who can provide guidance based on the specific circumstances and the overall status of the railway network. Dispatch can inform the engineer about the status of the track ahead and if it is safe to proceed, thus ensuring safety and proper protocol is followed.

Taking immediate action without consulting dispatch could lead to confusion or unsafe conditions, especially if other trains are affected by the signal malfunction. It is crucial to maintain clear communication in these situations to make informed decisions based on the most current information available.
