Abstract
A train detection system and method in which a transmitter transmits a train detecting signal, a receiver receives the train detecting signal, and a control device on the ground which is connectable to the transmitter and transmits the train detecting signal to the transmitter and receives the train detecting signal from the receiver. The transmitter adds first unique code data to the train detecting signal transmitted from control device on the ground and the receiver adds second unique code data to the train detecting signal. The control device on the ground collates whether the first unique code data and the second unique code data received from said receiver coincide with predetermined data contents.
