A transmission line 5 configured to be broken when it comes into contact with a rail 4 is installed on a disengagement prevention guide 1 attached to an axle box 3 of a railway vehicle. One end 5a and the other end 5b of the transmission line 5 are connected to a determination unit 6 to monitor continuity of the transmission line 5. In the event of a derailment, the determination unit 6 determines that a derailment has occurred when the disengagement prevention guide 1 makes contact with the rail 4 and the transmission line 5 breaks, thereby interrupting the continuity of the transmission line 5. 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.
