The axle-box acceleration is regularly measured by the track inspection car in Japan. We examined the technique for managing the rail corrugation by making use of the axle-box acceleration measured by the inspection car. Concretely, we analyzed the relation between the axle-box acceleration data and the rail surface roughness data measured on the ground. In that case, the influence of the difference of the measurement axle of the bogie and the difference of measuring speed of the axle-box acceleration on the detection accuracy of the rail surface roughness was examined. As a result, we have confirmed that the rail corrugation is able to be managed efficiently by using the axle-box acceleration measured by the leading axle of the bogie in case where the track inspection car runs with a usual speed.
