What action should be taken when a train is in door bypass and encounters a signal displaying stop?

When a train is in door bypass mode and encounters a signal displaying stop, the most appropriate action is to proceed according to train order. In door bypass mode, the operator has overridden the door safety mechanisms, which allows for flexibility regarding the train's operation. However, encountering a stop signal under normal circumstances would typically require the train to halt.

However, when there are specific train orders or instructions in place, those directives take precedence. This means that the train operator must adhere to the instructions provided through train orders, which can delineate how to proceed when signals are not aligned with the immediate operational needs of the train.

It's critical to recognize that this approach aligns with the protocol set forth in the operating rules, prioritizing adherence to established procedural orders when they are issued as a directive for the operation of the train. Thus, in situations where conditions and existing orders diverge, the operator must follow the explicit guidance of the train orders to ensure safety and compliance with operational protocols.
