Abstract

PURPOSE: To provide an opened-circuit type train detecting device attached to a closed-circuit type AC track circuit wherein, even when an outer disturbance such as circuit breaking of a closed-circuit type AC track circuit, an instantaneous service interruption of a signal source or the like occurs, a detection relay is made inoperative, thereby imparting no erroneous dection output to an approach locking circuit.
