If the "ACSES Failure" light is illuminated on the Intelligent ADU, what action should the engineer take?

When the "ACSES Failure" light is illuminated on the Intelligent ADU, the appropriate action for the engineer to take is to cut out ACSES. This is because ACSES, which stands for Advanced Civil Speed Enforcement System, is a safety system designed to monitor and enforce train speeds. An illuminated failure light indicates that the system is not functioning properly, which could compromise safety.

In this situation, cutting out ACSES allows the engineer to safely continue operations while adhering to manual speed restrictions and any other operational protocols. It's crucial to resolve the ACSES issue to ensure safe train operations, and cutting it out is a standard procedure to avoid reliance on a malfunctioning system.

Continuing to operate the train without addressing the failure would pose a safety risk. Increasing speed is also unsafe because it disregards the potential hazards due to the failure. Contacting the control center could be a necessary step later, but immediate action is required to manage the ACSES failure appropriately.
