After an enroute ASC failure, what should you do with ASCDT-1?

In the event of an enroute Automatic Speed Control (ASC) failure, it is required to remove ASCDT-1, which is the form used to document the failure, from the cab of the locomotive. Retaining the form in the cab could lead to confusion or misuse, especially if the ASC system is considered out of service during the journey. By removing it, it ensures that the crew has a clear understanding of the state of the control systems in use and prevents the possibility of inadvertently attempting to re-engage a system that is known to be defective.

The process is essential for safety, allowing the crew to focus on operational protocols without the distraction or misleading presence of the ASC device documentation in the cab. The failure must also be reported up the chain of command to ensure that proper records are maintained and that any necessary actions can be taken to address the issue after arriving at the next stop.

This is why the appropriate action is to remove ASCDT-1 from the cab, ensuring both crew and operational safety during the journey.
