Abstract
A train detection system is capable of realizing reliable train detection with a train detection apparatus of simple construction using a track circuit. This is attained by a transmitter 11a adding data of a first unique code to a train detecting signal received from wayside controller 100 and transmitting it to a track circuit; a receiver 11b adding data of a second unique code to the train detecting signal added with the first unique code data received from the track circuit and transmitting it to the wayside controller 100; and the wayside controller 100 checking whether or not the data received from the receiver 11b agrees with predetermined data.
