The high impact force and varying crossing geometry at railway turnout cause rolling contact fatigue damage and accumulated plastic deformation which affects the life of the wheel-rail contact interface. This subjects the wheel-rail material to fatigue damage at lower cycle under tangential contact force compared to the normal contact force. In addition, the involved contact dynamics at rail turnout has significant impact on the dynamic response of the system. To investigate the problem related to wheel-rail contact damage at railway turnout, simulation and analysis of the wheel-rail contact dynamics considering the acting forces and the resulting motions is necessary. This article presents the results of a study conducted on wheel-rail contact at railway turnouts using a multibody dynamic modelling and simulation tool (SIMPACK). The SIMPACK wheel-rail model and simulation results have shown that the wheel-rail dynamics simulation parameters such as joint position, velocity, acceleration, force and torque on wheel sets are constant for the straight tracks and not constant for curved/sharp edged tracks. From simulation results, it has been observed that the wheelset stability, train punctuality and life of wheel-rail surface depend on track type and can be affected by the track geometry.
