In what mode is the train allowed to bypass certain speed controls?

The mode that allows a train to bypass certain speed controls is known as Release mode. In this mode, the train can operate without being subject to restrictive speed controls that are typically in place to ensure safety and compliance during regular operations.

Release mode is used in specific situations, such as when a train is being moved for maintenance purposes or in certain operational scenarios where lower safety restrictions can be safely applied. This allows for increased efficiency in the movement of the train under controlled conditions while still maintaining a framework for safety.

Other modes like MATC, Prime, and Normal maintain standard operational parameters where speed limits and controls are strictly enforced to ensure safety. Understanding these different modes is crucial for engineers and operators when managing the safety and efficiency of train operations.
