Beschreibung
Zusammenfassung:	An object is to provide a rail fracture detection device 5 capable of detecting a fracture of a rail in a track circuit without using train positional information. The rail fracture detection device 5 detects a rail fracture in a section provided with the track circuit by determining presence or absence of a rail fracture and determining presence or absence of a train on a rail by using information on whether a relay of the track circuit is activated or deactivated and information on a current value of current flowing in the track circuit. The rail fracture detection device 5 is preferably provided in a section including a curved portion or a section including a welded portion in which a rail fracture is more likely to occur.
