Iwnicki, Simon, Allen, Paul and Stow, Julian (2005) Wheel/rail interface issues. Journal of the the Permanent Way Institution, 123 (3). pp. 123-127. ISSN 2057-2425

The equations for the forces developed between the wheel and rail are summarised and the physical implications are explained in terms of the behaviour of the wheelset and the vehicle. The computer tools based around these equations that allow prediction of the behaviour of a railway vehicle are discussed. The importance of input data such as wheel and rail profiles and track geometry is explained and examples of typical outputs and how these can be used to provide guidance on safety and maintenance presented. Finally, advice is given for the use of simulation of vehicle dynamics to ensure best practice in the management of the wheel-rail interface for light rail systems.
