Abstract The multibody simulation of railway dy- namics needs a reliable efficient method to

evaluate the contact points between wheel and rail. In this work some methods to evaluate position of contact points are presented. The aim is to develop a method which is reliable in terms of precision and can be imple- mented on-line, assuring a calculation time consistent with real-time calculations of multibody dynamics.
