Imazatosuji Line (Line No.8) of Osaka Municipal Subway is a LIM system which contains many sharp curves. In order to reduce mainly corrugation which occurs on low rail in sharp curve section, friction modifier is applied to top of low rail. From the day to day experience we find, friction modifier can not only reduce the formation of corrugation but also improve curving performance of vehicle. Unfortunately, just limited research data related to this experience is published. To elucidate the phenomena scientifically, wheel load, lateral force, angle of attack, displacement of wheelset and rail were measured under multiple friction conditions between wheel and rail contact. From the measured result we grasped the influence of interface friction condition on lateral force. This research also helps us to find the optimal level of friction modifier application.
