This paper demonstrates the possibility to estimate the track irregularities of Shinkansen tracks using car-body motions only. In an inverse problem to estimate track irregularity from car-body motions, a Kalman Filter was applied to solve the inverse problem. This technique is utilized to estimate the track irregularity in longitudinal level. It can be concluded that the track irregularity estimation in longitudinal level is possible with acceptable accuracy for practical use with method.
