In this investigation, a numerical procedure that can be used for the analysis of wheel/rail two-point contact geometries in turnout section is developed. Since the tongue rail changes its shape along the track in the turnout section, the cross-sectional shapes and their derivatives used to determine the orientation of the tangent plane of the tongue rail is generated by interpolations along the rail and used for evaluating the location of contact points on stock and tongue rails. Numerical examples in point section are presented in order to demonstrate the use of the procedure developed in this investigation and the effect of wheel profiles on the contact configuration in turnout section is discussed.
