What happens to train operation during ATC Bypass mode?

In ATC Bypass mode, the primary concern is safety and ensuring that operations proceed according to established protocols. Initial movements being compliant with safety protocols is crucial because bypassing automatic controls can introduce risks. This means that while the engineer is given more operational flexibility during this mode, specific safety measures must still be adhered to at the outset to prevent accidents or unsafe conditions.

The need for compliance with safety protocols reflects the potential hazards that increased human control may introduce. Thus, while there are more lenient operational controls in Bypass mode, the system requires that the train engineer follows safety measures to mitigate any risks associated with manual operation. This principle underscores the importance of maintaining a high standard of safety even when certain automated systems are not active.

This choice emphasizes the balance between operational control and safety critical to train operations, highlighting that full manual operation does not equate to unrestricted movement. Other options do not adequately represent the necessary safety considerations associated with operating in ATC Bypass mode.
