Abstract
A transmission lineconfigured to be broken when it comes into contact with a railis installed on a disengagement prevention guideattached to an axle boxof a railway vehicle. One endand the other endof the transmission lineare connected to a determination unitto monitor continuity of the transmission line. In the event of a derailment, the determination unitdetermines that a derailment has occurred when the disengagement prevention guidemakes contact with the railand the transmission linebreaks, thereby interrupting the continuity of the transmission line. This arrangement allows an accurate detection of a derailment, so as to prevent a railway vehicle from traveling when its wheels have become disengaged from a rail without an operator being aware of it, thus improving safety after the derailment occurs.
