In this paper, three dimensional contact geometry for measured profiles are studied. Three dimensional contact geometry requires the accuracy of profile data. But measured profiles contain measuring errors. In order to filter the errors, template method is proposed. The method uses the flange-ware function and reduces the error without changing the profiles. As an application of the method above, three dimensional contact geometry of worn profiles on a tight curve is calculated. Contact points, rolling radius differences and other geometric parameters are calculated when a wheelset moves in yaw direction. Geometric characteristics of a worn wheelset with attack angles on worn track in a tight curve are discussed precisely.
