What happens if a train transitions into Release mode while in motion?

When a train transitions into Release mode while in motion, it initiates a process that includes an emergency brake application. Release mode is designed to signify that the train is releasing its brakes, but it is important to understand that this action is contingent upon the operational context of the train's systems. An emergency brake application acts as a safety mechanism to prevent any uncontrolled movement or potential accidents.

In operations where the train is in motion and switches to Release mode, the system interprets this as a loss of control, which is why the emergency brake is activated to secure the safety of the passengers and the train itself. This response ensures that if the transition to Release mode is unintended or occurs during unsafe conditions, it actively manages the risk by applying the brakes immediately.

The other potential scenarios of maintaining a speed or switching controls do not accurately reflect the safety protocols integrated into train operation systems. Such measures are necessary to uphold safety standards within rail transport environments.
