Track circuits consist of rails and rail insulation, used for automatic and continuous detection of train occupancy, and for controlling signaling or switching devices to ensure safe train operation.
The entire track network is divided into numerous block sections at appropriate intervals, each separated by rail insulation joints to form an independent track circuit. Each section's starting point has a signal (color light signal). When a train enters a block section, the track circuit immediately reacts and transmits information to the signal that the section is occupied, preventing other trains from entering. The signal at the section entrance then displays a stop signal. Y-series (DC) circuit breakers with two auxiliary contactors and B-series circuit breakers are used.

# Railway signal
Axle counter, also known as microcomputer axle counter, is equipment installed at railway stations at both ends. It uses closed-loop sensors installed on the rails to monitor the number of wheel pairs passing through. After detection, the number of wheel pairs at this station is sent to the opposite station via a semi-automatic device in the indoor microcomputer system. When the train arrives at the opposite station, if the number of wheel pairs received by the opposite station is the same as that of the departure station, the section will be automatically opened. In other words, it is a railway signaling device that detects the passing of wheels, and it can replace many ordinary track circuits. Y-series circuit breakers are selected.
