In ATC Bypass mode, who is responsible for ensuring speed compliance?

In ATC Bypass mode, the engineer assumes full responsibility for ensuring speed compliance. This mode is typically utilized when there is a malfunction in the Automatic Train Control (ATC) system that requires the engineer to manually control the train's operations. As a result, the engineer must closely monitor speed limits and adhere to all operational procedures to ensure safety.

While the system is designed to automate many controls under normal operating conditions, once it is bypassed, any automatic functions associated with speed regulation are no longer in effect. The engineer must rely on their training and knowledge of the train's handling capabilities, track conditions, and signal indications to maintain the proper speed throughout the journey.
