Abstract

PURPOSE: To restrict the range in which rate of variation in the voltage applied to a track relay is changed, by providing an insulating reactor transformer LT having a low impedance in a track circuit.
CONSTITUTION: Rails 1, 2 are divided into a plurality of sections through provision of insulators 3, and insulating reactor transformers LT are connected between the current feeding rail and current transmitting means or otherwise between the current receiving rail and track relay means. If a trouble that the reactor transformer is opened is caused, transmission of current is interrupted and voltage applied to the track relay TR drops to zero, whereby safety operation of the system can be ensured.
