What condition must be met before operating in Release mode?

In order to operate in Release mode, it is essential that the transition occurs after the train has come to a complete stop. This is crucial for safety and operational integrity, as entering Release mode while the train is in motion could lead to a loss of control or complications in the system’s ability to manage its operations effectively. Ensuring that the train is stopped provides a stable environment for the transition, minimizing risks associated with speed, track conditions, or operational signals.

Other conditions, such as minimum speed or track designation, may play a role in operational procedures but do not specifically relate to the transition into Release mode. Clearance from the operations center serves a different purpose, ensuring coordination and safety in train operations, but does not directly dictate the mechanics of shifting to Release mode. Thus, the requirement for stopping before making this transition is the key factor that ensures both safety and compliance with operational protocols.
