To provide a method by which a detection speed of a railway vehicle abnormal travel is increased while a detection accuracy of the abnormal travel is not worsened.SOLUTION: An abnormal travel detection device for a railway vehicle comprises a storage device preliminarily storing at least one initial waveform pattern which is an initial part of an abnormal travel waveform equivalent to a detected signal waveform of a vibration sensor generated during an abnormal travel of the vehicle, a first abnormal travel determiner which calculates the coincidence of a waveform of the detected signal received from the vibration sensor with the initial waveform pattern and determines that an abnormal travel occurs when the coincidence satisfies a prescribed coincidence criteria and a second abnormal travel determiner which determines whether the detected signal received from the vibration sensor satisfies a prescribed abnormal travel condition or not when the first abnormal travel determiner does not determine that the abnormal travel occurs.SELECTED DRAWING: Figure 6
