In order to verily the validity of "the Detailed Equation" which is a method of static analysis on railway vehicle overturning, we conducted a full scale experiment. The Detailed Equation is an equation of the equilibrium of the forces that act on a railway vehicle, which is similar to an equation for solving the overturning problem of a rigid body, but the external forces and the displacement of the car body are taken into account in detail. In the full scale experiment, we loaded lateral force (assumed to be crosswind) on the test vehicle, and examined the behavior of the vehicle, such as displacement of the car body and variation of wheel load. As a result, the Detailed Equation has been verified to be valid when we use it for evaluating the critical wind speed of overturning or the wheel unloading ratio.
