Whose permission is necessary to operate electric locks on switches?

To operate electric locks on switches, the permission of the train dispatcher or control operator is necessary. This is because the train dispatcher is responsible for managing train movements and ensuring the safe operation of the railway network. They have a comprehensive understanding of the current status of the train operations, including which tracks are clear and which are active, allowing them to make informed decisions about when and how locks can be engaged or disengaged.

This permission is vital for maintaining safety protocols. The dispatcher ensures that all movements are controlled and that no conflicts arise between different trains, which could lead to accidents. Their role is integral to coordinating the overall flow of train traffic and managing any potential hazards associated with switch operations.

The other options, such as the engineer in charge, station master, or safety officer, although they play critical roles in train operations, do not hold the specific authority needed to operate electric locks on switches. Each of them has particular responsibilities, but the control of switch operations falls specifically under the domain of the dispatcher or control operator. This defined structure helps maintain clear lines of responsibility and enhances overall safety in railway operations.
