A vehicle abnormality detecting apparatusincludes wheel load sensorsthat are attached to right and left rails R constituting a track to measure wheel loads of wheelsprovided in a vehicle; and a calculation unitthat is connected to the wheel load sensors. An index represented by wheel loads of a pair or more of right and left wheelsprovided in at least one of bogiesand defined according to a type of vehicle abnormality as an index for detecting the vehicle abnormality is previously stored in the calculation unit. The calculation unitcalculates a value of the stored index from the wheel loads measured by the wheel load sensorsand transmitted from the wheel load sensors, and detects the abnormality of a running vehicle based on the calculated value of the index.
