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 2):
A railway vehicle derailment detection device for a railway vehicle traveling on a rail, comprising:\n a member that is installed in a portion of the railway vehicle, the member being configured to be broken when a portion of the railway vehicle comes in contact with a rail or a ground-based equipment installed on an inner side of a pair of rails; and a device that determines that a derailment has occurred by detecting that the member has been broken when the portion of the railway vehicle comes in contact with the rail or the ground-based equipment.
