Abstract
This paper introduces experimental set-up for corrugation development on the flexible rail. The wheel drives on the track, which have flexible rail in part of track with longitudinal slip. There is the ruggedness at the center of flexible rail to generate the longitudinal slip. This experimental equipment also can generate the longitudinal slip by the slip generator that gives difference between wheel rotation and wheel velocity. So corrugation develops on the flexible rail gradually. We measured the corrugation profile by laser displacement sensor.
