In real exploitation conditions of railway vehicle exist an interaction of wheels and rails with different state of wear. The wear of those surfaces influences also the geometric parameters of each wheel-rail pair. Followed by those are changes of contact forces between wheels and rails and changes in the dynamic behavior of a rail vehicle. To assess the vehicle dynamic behavior a series of simulations were performed in a wide range of traveling speeds. The object under study was conventional

In all the cases track irregularities and wheel and rail profiles have been previously measured. Obtained results such as vehicle accelerations and wheel-rail contact forces were analyzed in amplitude and frequency domain.
