What does signal timing refer to in railway operations?

Signal timing in railway operations specifically refers to how long a signal remains in one particular state, such as "stop" or "go." This duration is crucial because it determines how long trains must wait at a signal or how long they can proceed safely without having to stop. Proper signal timing ensures that train flow is coordinated effectively, reducing wait times and improving overall safety on the railway network.

By managing the timing of signals, rail operators can optimize traffic management, prevent collisions, and ensure that trains operate within safe parameters. For instance, if a signal stays green for too long, it could lead to traffic congestion or safety hazards if a train encounters a situation that requires an immediate stop. Therefore, understanding and managing signal timing is critical in efficient railway operations.
