Abstract

The invention relates to a method for detecting a derailment of a rail vehicle (1) having at least two car bodies (2a, 2b) connected to each other via a joint (8) such that the longitudinal axes (9a, 9b) of the car bodies (2a, 2b) are angled relative to each other during a curve travel of the rail vehicle (1), wherein a detection device (3) receives: - angular information about an instantaneous angle (MW) of the car bodies (2a, 2b) relative to each other, - positional information about an instantaneous position of the rail vehicle (1) in a rail network, - the instantaneous angle (MW) is compared with an expected angle (EW) for the instantaneous position, and - if the instantaneous angle (MW) deviates from the expected angle (EW), an output signal is issued indicating a derailment of the rail vehicle (1), or the output signal is terminated.so that the absence of the output signal indicates a derailment of the rail vehicle (1).
