There is provided an abnormality detection apparatus for rail vehicles capable of deciding on abnormality of what portion of a vehicle causing abnormal vibration of a vehicle, when occurring. The abnormality detection apparatus acquires vibration data and operation data such as a traveling position, traveling speed, and a vehicle occupancy rate of two or more multiple rail vehicles, analyses the acquired vibration data and operation data, distinguishes whether a rail vehicle is placed in normal or abnormal condition, and, based on a result of comparison between vibration data of a vehicle placed in normal condition and vibration data of a vehicle placed in abnormal condition, decides on a cause of abnormality of vibration in one of the rail vehicles.
