This safety device automatically controls the train's course, and prevents collision and crash accident. With the choices of the electronic circuit and computers, it enables safe train services, and provides much more excellent services than the interlocking relay system of the past or any other devices used in trains. The important parts of the device were especially designed in triple layers to enhance the reliability of the data, to establish the safety when running the trains.
This is a system that directly controls the train system according to the fixed course by the electronic interlocking system. It controls and maintains the train's speed, controls the trigger receive assembly, automatic control of the train services between the stations, etc. Like the electronic interlocking system, the important parts were designed in triple layers to enhance the reliability and safety. Also, it always enables the trains to maintain a certain (safe) distance. So, when it comes within a certain distance or when there are minor troubles in the system, the train is automatically stopped, to reinforce the safety of the passengers.
When there is a need to change the course of the train, this equipment changes the course with electric power, and includes a locking device which does not let the train move until the entire train is fully through the system after its direction change. The equipment changed its energy transmission systems from the mechanical system to the electronic system (magnetic clutch). The electronic system is not affected by the temperature changes during summer or winter, which minimizes the mechanical problems.
Track circuit device examines the train to understand its current location, and checks the train's safety. Also, the tracks are made with electronic circuits, and sends various information needed in the train services through this track circuit device.
This is a system that lets the engine driver know whether to drive the train or not. It receives the absolute safety conditions from the electronic interlocking device and shows the signal which the engine driver can visually confirm. This sends a clear signal automatically when the train is into a certain point in the tracks according to the fixed time schedule of the train services. When the running conditions are not sufficient, the red light comes on for the train to not proceed into the tracks.
