An object of the present invention is to propose a new method for ensuring the stability of railway operation. SOLUTION: An inter-comparison is made between an actually measured disturbance value obtained by observing a resistance force exerted on a railway vehicle due to a topographical factor at the operation position of the railway vehicle and a reference disturbance value already stored in relation to the operation position. A railway vehicle abnormality determination device and a railway that can determine the presence or absence of an abnormality in a railway vehicle without using an additional sensor or device in the railway vehicle by determining whether or not the railway vehicle is abnormal based on the result value obtained A vehicle abnormality determination method is proposed.
