If the cab signal fails en route in 562 territory, what is the initial action the Engineer must take?

When a cab signal fails en route in 562 territory, the initial action the Engineer must take is to notify the Dispatcher as soon as possible with the details of the failure. This is essential because the Dispatcher must be informed of any safety-critical issues that could affect train operations. The Dispatcher is responsible for managing the train's movements and can provide guidance, additional instructions, or take necessary actions to ensure safety.

Prompt communication about a cab signal failure allows for quicker assessment of the situation. The Dispatcher can then determine whether to reroute the train, provide alternative signal instructions, or advise the Engineer on how to proceed safely. This immediate notification is critical in maintaining safety protocols and ensuring that all relevant personnel are aware of the situation.

Continuing operation until reaching the next station would not be advisable as it could compromise safety. Checking for alternate signaling instructions could be secondary but follows after notifying the Dispatcher, who might already have the necessary information or procedures to follow. Shutting down the locomotive for inspection might be a later step, but it is not the first action to take in the event of a cab signal failure.
