The rail is one of the most important elements in constructing railway system. The phenomenon such as wear or defect will occur caused by the repeated wheel/rail rolling contact. The wear of rail, which does not occur in a short period of time, has a close relation to crack initiation. And there is a possibility that it influences the running stability or the curving performance of vehicle due to the change in the rail profile attributable to it. Therefore, it is very important to analyze the wear development of the rail. The wear of rail occurs more outstandingly in the curved section than in the straight section. In the curved section, the wheel passes with an attack angle, which gives rise to not only longitudinal slips but also lateral slips at the wheel/rail contact patch. In previous research, longitudinal slips and lateral slips have been treated as the equivalent. In this research, we conducted wear experiments to examine the influence of lateral slip on wear development.
