Abstract
A purpose of the invention is to provide a rail breakage detection device mountable also on a vehicle. The invention is directed to a rail breakage detection device that receives: transmission-device state information indicating whether a rail signal transmission device that sends a rail signal is normal; reception-device state information indicating whether a rail signal reception device that receives a voltage induced by the rail signal is normal; and reception state information indicating whether a voltage induced by the rail signal reception device is received, and the rail breakage detection device performs rail breakage detection on the basis of the transmission-device state information, the reception-device state information, and the reception state information.
