Track Circuit Technology

Track circuit technology is a railway safety system that detects whether a section of track is occupied by a train. It uses electrical or electronic signals across the rails; when a train is present, it completes an electrical circuit, signaling the control systems that the track is busy. This information allows for safe train operation by preventing collisions and managing traffic flow. Essentially, it acts like an electronic "occupancy sensor" embedded in the track, providing real-time status updates to train control centers to ensure safe and efficient railway operation.
