The rolling contact geometrical parameters and creepages of JM3 wheelset and 60kg/m rail track in static rolling contact were analyzed under different track structural parameters. On the basis of the contact geometrical parameters and creepages of wheel-rail, the effects of track parameters wheel/rail contact patch behavior were investigated using the rolling contact theory of three-dimensional elastic bodies with non-Hertz form and numerical program of CONTACT. The numerical results indicate that the rolling contact behavior of wheel/rail is not achieving the optimal state when the rail base slope is 1/40. So, it is suggested that the profile of wheel/rail tread is optimized. The rail gauge has obvious effect on contact geometrical parameters and creepages of wheel/rail. Considering the operational safety of rolling stock, the rail gauge can be increased properly under small curve radius condition.
