What does “shunting” in railway signals refer to?

Shunting in the context of railway signals refers to the process of redirecting signals to control train traffic and ensure safety on the tracks. This system is crucial because it allows for the coordination of train movements, especially at junctions or intersections where multiple tracks converge. By managing the signals appropriately, it prevents collisions and ensures that trains are directed safely along their intended routes.

Shunting can involve changing the state of signals to indicate whether a section of track is clear or occupied, thus helping train operators make informed decisions. It plays an essential role in maintaining the efficient operation of the railway system.
