This paper describes a computer model simulating the running performance of a two axled railway-bogie passing a switch. Especially emphasised is the exact mathematical description of the switch blade and stock rail geometry taking into account the asymmetrical situation. The sequence of different rail profiles during the time step simulation is in strong contrast to investigations on ordinary track sections thus demonstrating a possiblity to optimize vehicle parameters including the running performance on switches. On the basis of a 14 degrees of freedom model [2] the investigations analyze the running performance by the geometric and kinematic behaviour as well as forces of the rail/ wheel contact. As an approach to an improved high-tech solution an actively steered bogie is considered which is based on the idea of radial forced steering of the wheelsets using information about the local track curvature.
