Abstract
A train detection system, including a transmitter, to be connected to a track circuit, which transmits to the track circuit a train detecting signal for confirming the existence of a train in the track circuit, a receiver, to be connected to the track circuit, which receives the train detecting signal from the transmitter through the track circuit, and a wayside controller. The wayside controller is connected to the transmitter and the receiver through a data transmission path, which transmits the train detecting signal to the transmitter and receives the train detecting signal from the receiver. The wayside controller includes a checker for checking whether or not the train detecting signal, which is received from the receiver, agrees with the contents of predetermined data.
