This paper presents measurement and analyses of wheel/rail contact geometry in tight curving. Examination of wheel/rail contact conditions is one of the most fundamental problems for railway vehicle dynamics. In this paper, basic experiments were made with an actual bogie and full scale test track. The lateral position and yaw angle of wheelset, and contact patch were measured in tight curve condition. These experimental results are compared with numerical calculations which are based on three-dimensional two-point contact analysis proposed by authors. It was found that there are good agreements in comparison between measurements and calculations.
