Abstract:
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  5 a  and the other end  5 b  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.

Claim (Index 3):
The railway vehicle derailment detection device according to  claim 2 , wherein:\n the portion of the railway vehicle that makes contact with the rail in the event of a derailment comprises a disengagement prevention guide attached to an axle box provided with a bearing that supports a rotatable wheel set; and the member configured to be broken due to contact with the rail comprises one of (i) a transmission line installed on a surface of the disengagement prevention guide that makes contact with the rail, (ii) a conductive coating applied on top of an insulating coating, (iii) a power supply line for transmitting brake signals to all of the constituent railway vehicles, (iv) a wiring of a detector for measuring vibration and/or temperature of the axle box, (v) a vibration accelerometer, or (vi) a temperature sensor.
