TRAIN DETECTOR FOR LEVEL CROSSING PROTECTION

A TRAIN DETECTOR FOR THE USE OF THE LEVEL CROSSING ALARM INITIATION WAS DEVELOPED. IT DOES NOT REQUIRE ANY EXCLUSIVE LINE WIRES BETWEEN THE DETECTOR, AND THE CROSSING LIKE IN THE STANDARD TYPE DETECTOR NOW IN USE IN JNR. THE DETECTOR IS ATTACHABLE TO ANY PART OF A CONVENTIONAL AC TRACK CIRCUIT AND CAN DETECT APPROACHING TRAINS BY DECREASE OF TRACK VOLTAGE TO SPECIFIED VALUE. THE DETECTED INFORMATION IS TRANSMITTED TO THE CROSSING WITH A CARRIER FREQUENCY OVER A PAIR OF EXISTING LINE WIRES. THE EFFECT OF ATTACHING THE DETECTOR ON THE TRACK RELAY IS NEGLIGIBLY SMALL.
