摘要： When a prior art track circuit for monitoring an electric signal supplied to a rail via a transmitter and a receiver connected to the rail for detecting a presence of a train using a phenomenon in which the reception level of a signal drops when axles of a train electrically short two rails together and sending a train control signal to the train is applied to a dual gauge track circuit in which two types of trains having different gauges share a rail, mutual induction between rails occurs which is a problem specific to the dual gauge track circuit, and the amount of attenuation of the train detection signal when a train is present on a track drops. The present invention prevents the mutual induction between rails and suppresses the drop of the amount of attenuation of the train detection signal when a train is present on a track by providing a train detector for recognizing two types of trains and detecting the presence of trains on the track via transmitters and receivers respectively connected to three rails, including filters for passing relevant signals and increasing the impedance of signals of other signal bands disposed on input stages of the respective receivers.

摘要： The invention solves the prior art problem of signals not being transmitted between ground and vehicle when a train stops so that a cross point of a loop coil or a boundary between two loop coils is positioned between antennas disposed on a front side and a rear side in a direction of travel of the train. The present invention provides an arrangement in which two or more antennas are disposed on a front side and a rear side in the direction of travel of the train and providing a difference in signal levels received via the respective antennas, so that even when the train stops with the cross point of the loop coil positioned between antennas disposed on the front side and the rear side in the direction of travel of the train and the signals received via the front-side antenna becomes reverse phase with the signals received via the rear-side antenna and the signals are cancelled out, the signals having a higher reception level remains without being cancelled out, and therefore, a given level of transmission and reception can be obtained.
