Abstract
Not only the corrugation wear of railroad causes vibration and noise, but also it is mentioned as one of the factors which are connected with the derailment. Before, As this corrugation wear countermeasure, the re-profiling method by face grinding has been used. However, the problems that the grinding distance per unit time is short and that it is difficult to get a smooth plane, and that a re-profiling machine is expensive, are also being taken up in this method. Then, as the new efficiently method, a platen polishing with the ML(Multi-Layered ) belt is noticed. In this study, polishing characteristic of ML belt is developed.
