What does ATC Bypass mode enable the engineer to do?

ATC Bypass mode is specifically designed to allow the engineer to operate the train during a complete failure of the automatic train control (ATC) system. When ATC fails, the normal automatic controls that govern speed and train movement are no longer operational, which could pose significant safety risks if the train cannot move at all. Activating ATC Bypass mode provides the engineer with the necessary ability to manually control the train, ensuring that it can continue to operate safely and reach its destination while the engineer maintains full oversight of the train’s operation.

In this mode, the engineer is expected to adhere to the manual operating protocols and must still be vigilant regarding speed and signal compliance since the automatic controls are not active. This mode is a contingency that prioritizes safety and operational continuation while allowing the engineer to maintain control over the train under circumstances where the automatic systems cannot function.
