What is the signal status when operating in ATC Bypass mode?

In ATC Bypass mode, the signaling system is bypassed to allow the train engineers to operate the train manually, often during situations such as signal failures or maintenance work. When operating in this mode, the signals are not utilized to convey aspects to the train operator, which means there are effectively no signals indicating the status of the train's operation. This setup is important as it requires the train engineers to rely on their training and operational protocols while adhering to safety procedures without the aid of automated signal guidance.

The absence of signals during ATC Bypass mode emphasizes the necessity for engineers to be vigilant and knowledgeable about the track and surroundings while managing the train's movement manually. It reinforces the importance of understanding operational protocols to maintain safety when standard signaling methods are unavailable.
