Track circuit AF track circuit

summary
The A.F track circuit system is, the most optimal system for on-board signaling which can be divided into different forms according to its design method. is the system also demonstrates technical change by codifying the train operation and control information and transmitting them to trains and on-site equipment through inductive radio It not only functions simple train detection, but transmits the distance from the preceding train, the given speed of the train, train operation information to the locomotive and directly connects to the brake system and automatically stops the train which enters ignoring the signal and therefore it achieves the safe train operation.
