The axle-box acceleration (ABA) is regularly measured by the track inspection car in major Japanese railway operators. We developed a new technique for managing rail corrugation by making use of the ABA measured by the track inspection car. Concretely, we analyzed the relation between the ABA data and the rail surface roughness data measured on the ground. Furthermore, we examined the influence of the measurement axle in the bogie and the train running speed of the ABA on the detection accuracy of the rail corrugation by using the ABA. As a result, we have confirmed that the rail corrugation can be managed efficiently by using the ABA measured by the leading axle of the bogie in case where the track inspection car runs with a usual speed.
