How should trains enter the main track at a hand-operated switch without a governing signal?

When trains are entering the main track at a hand-operated switch without a governing signal, it is crucial for safety and order that authority be obtained from the control operator. This is because the control operator has the responsibility for managing train movements and ensuring that the main track is clear and safe for the train to enter.

Obtaining authority ensures that all necessary communications have been made, and that the train dispatcher is aware of the current situation on the track, preventing potential collisions or accidents. This protocol is a fundamental part of maintaining safety and coordination on the railway network, especially in situations where signaling systems may not be active or operational.

The requirement to get authorization emphasizes the importance of communication and regulation in rail operations, which is vital for the safe movement of trains, particularly at points where manual operations like hand-operated switches are in use. Other considerations, while important, do not provide the same level of assurance and safety that comes with obtaining the proper authorization from the control operator.
