Example
Modern track circuits can detect even the smallest metal objects on the tracks.
Track circuits are essential for preventing collisions on busy railway lines.
Engineers regularly check the track circuit to make sure it is working correctly.
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.
