Abstract
A train detection system, having a transmitter which transmits a train detecting signal, a receiver and a wayside controller connected to the transmitter and the receiver through a data transmission path. The transmitter adds a first unique code assigned to the transmitter to the train detecting signal received from the wayside controller and transmits the thus processed train detecting signal and the receiver adds data of a second unique code to the train detecting signal and transmits the thus processed train detecting signal. The wayside controller includes a unique code checker for checking whether or not the first unique code data and the second unique code data agree with the contents of predetermined data.
