Multi-Body System (MBS) computer modelling is frequently performed in the design-phase of railway vehicles and increasingly for virtual testing in the process of rolling stock authorisation. There is a growing necessity to improve knowledge on the effects of different modelling choices on simulation results. In this article a validation exercise is presented. The results show an unusually high tread friction coefficient and the importance of modelling the presence of lubricant on the flange for a satisfactory match between simulated and experimental results. Conclusions address the validation of MBS models, the design and virtual testing of rolling stock.
