Wheel and rail geometry has a significant influence on the dynamic behavior of railroad vehicle systems. This chapter discusses the geometries of wheel and rail surfaces, which are fundamental in defining the kinematic and dynamic equations of railroad vehicles. This chapter discusses two approaches for describing rail geometry: the semi‐analytical approach and the absolute nodal coordinate formulation interpolation approach. The first disadvantage is the need to evaluate the derivatives of angles with respect to the rail longitudinal surface parameter in order to determine the tangent, normal, and curvature vectors. The second disadvantage is the low order of interpolation used to determine the position coordinates of arbitrary points on the rail with specific output from the track preprocessor, which is designed to generate the data required at discrete nodal points for use in nonlinear dynamic simulations of railroad vehicles.
