What is the primary purpose of the ATC Bypass mode?

The primary purpose of the ATC Bypass mode is to operate under specific restricted conditions. This mode is designed to allow trains to continue operating safely when the Automatic Train Control (ATC) system is not functioning normally or when a specific limitation requires the system to be bypassed. By engaging the ATC Bypass mode, operators can manage the train's movement while still maintaining a level of safety, even if the full capabilities of the ATC system are not available.

This mode is critical in scenarios where the train may encounter temporary restrictions, need to operate beyond its usual parameters, or when there are system malfunctions that necessitate a different operational approach. By doing so, the train can adhere to necessary safety protocols while enabling movement in conditions that would otherwise halt operations. It's important for engineers and operators to understand this functionality to ensure the safety of passengers and the integrity of the rail system.
