Track circuit
01
a safety system on railways that detects the presence of a train on a section of track
What is a "track circuit"?
A track circuit is an electrical system used to detect the presence of trains on a railway track. It works by sending an electrical current through the track, and when a train passes over, it completes the circuit, signaling that the track is occupied. This information is then used to control signals and ensure that trains do not travel on the same track at the same time, preventing collisions. Track circuits are commonly used in modern signaling systems to improve safety and manage train traffic efficiently, especially in busy or complex railway networks.
Examples
The track circuit ensures that no other train can enter a section of track that is already occupied.
When a train passes over a track circuit, it sends a signal to the control center.
