When is the ATC start button required to be pressed during MATC operations?

In MATC (Modern Automatic Train Control) operations, the ATC start button must be pressed every time the train comes to a full stop. This requirement is crucial for ensuring that the train control system is reactivated and operating properly after a complete halt. Pressing the start button serves as a signal to the system that the driver is ready to resume operations, allowing for the immediate application of control protocols necessary for safe movement.

This procedure helps maintain safety by ensuring that each stop is an intentional action recognized by the system, reducing the risk of unintentional starts that could lead to dangerous situations. It provides a clear cue to the ATC system that the operator is in control and prepared to proceed once it is safe. Understanding this process is vital for safe train operations under MATC.
