Abstract

A train detection system includes transmitters receivers connected to a track circuit for transmitting and receiving a train detecting signal to and from the track circuit, and a control device on the ground, which transmits the train detecting signal to the transmitter and receives the train detection signal from the receiver. The transmitter adds a first unique code data to the train detecting signal received from the control device and transmits the same to the track circuit, and the receiver adds a second unique code data to the train detecting signal being added of the first unique code data received from the track circuit and transmits the same to the control device. The control device on the ground includes a storage portion and a collating portion which collates whether the first and second unique code data received from the receiver coincide with data stored in advance in the storage portion.
