Computer simulations of vehicle running performance create an integral part of research and development of new rail vehicles. The simulations allow e.g. optimization of dynamic behaviour of the vehicle and it may be possible to use them in the certification process instead of results of some track tests in the future. Nowadays, many commercial as well as non-commercial simulation tools are commonly used for these purposes. However, verification of the computational model and validation of its results represent the most significant problems which must be solved to gain relevant data from the simulations. In the framework of solving the R&D project “Competence Centre of Rail Vehicles” of the Technology Agency of the Czech Republic, the attention of the work package WP5 is paid to this problem of model validation among others. This paper deals with results of simulations of an electric locomotive through curves of various radii which were performed by means of four simulation tools (SJKV-L3A, SIMPACK in versions 8900 and 9.4-build65 and ADAMS/VI-Rail) at three different workplaces (Jan Perner Transport Faculty of the University of Pardubice, VÚKV a.s. and ŠKODA Transportation a.s.). The simulation results allow comparison of these different models as well as revelation and clarification of problematic aspects of the individual models.
