It is important to reduce lateral and longitudinal creep force on the contact point between wheel and rail in order that rolling stock runs safely and smoothly on curved tracks. Vehicle dynamics of rolling stock has been greatly affected by characteristics of creep forces on the contact point between wheel and rail. Excessive creep forces would possibly increase attack angle of wheelsets and lateral forces of wheel to rail. Consequently the increase of creep forces causes the decline of vehicle curving performance. As creep forces depend on friction coefficient of the contact point, the authors studied effects on curving performance by the difference of friction coefficient on the contact point between wheel and rail, and conclude the reduction of friction coefficient on inner rail can improve vehicle curving performance.
