摘要： PROBLEM TO BE SOLVED: To solve the problem wherein a damping quantity of a train detecting signal when a train exists on a line reduces, due to occurrence of mutual guidance between inherent rails in a three-wire track circuit, when applying a track circuit for monitoring an electric signal made to flow in the rail by a transmitter and a receiver connected to the rail, detecting the existence of the train from a phenomenon of reducing a receiving level by electrically short-circuiting between the two rails by a wheel shaft of the train, and transmitting a train control signal to a train to the three-wire track circuit having the rails shared by two kinds of trains different in gauge.
SOLUTION: A train detecting device detects a train existing line by recognizing the kind of two kinds of trains by the respective transmitter and receiver respectively connected to the three rails. Damping quantity reduction of the train detecting signal when the train exists on the line is restrained by restraining a mutual guiding characteristic between the rails, by arranging a filter set so that only the signal to an input stage of the respective receivers is passed and impedance becomes high in the other signal band.

摘要： PROBLEM TO BE SOLVED: To solve a problem that a signal cannot be transmitted between a wayside and a pickup device when a train stops so that a transposition point of a loop coil and a boundary of two loop coils are positioned between antennas arranged in front and rear with respect to the advancing direction of the train. SOLUTION: The pickup signal system is constituted by arranging a difference in a signal level received by the respective antennas by arranging two or more of antennas in front and rear with respect to the advancing direction of the train 1 so that even if a signal received by a front antenna and a signal received by a rear antenna are negated due to an effect that the signal has an opposite phase when the train stops so that the transposition point of the loop coil 2 is positioned between the antennas arranged in front and rear with respect to the advancing direction of the train, since a large signal of a receiving level remains without being negated, a predetermined transmitting-receiving level can be obtained.
