What is the correct position for the MC handle when activating the Door Interlock Bypass button?

The correct position for the MC handle when activating the Door Interlock Bypass button is in any brake position. This is important because it ensures that the system engages safety protocols while allowing the operator to bypass the interlock for necessary maintenance or operational checks.

When the MC handle is in a brake position, it indicates that the train's movement is controlled and stabilized, reducing the risk of accidental movement while the bypass is activated. This consideration is vital for safety, as it helps to prevent unintended actions that could lead to dangerous situations during procedures that involve accessing the doors.

Other positions, such as completely off or at full throttle, would compromise safety by potentially allowing the equipment to move unexpectedly, which can pose significant hazards to personnel working with or near the equipment. In summary, having the MC handle in any brake position provides a controlled environment that aligns with established safety protocols.
