Friction has a huge influence on the vehicle/track interaction and yet it remains poorly understood, its consideration an afterthought in many simulation activities. This survey of friction summarizes current understanding and identifies gaps requiring further development. Classical friction theory and modern approaches to modelling are reviewed, and lubrication and friction management practices are discussed. Methods for measuring friction at the wheel/rail contact, in both small and full scale systems, are documented.

The main aim of this project was to develop a wheel-rail creep force model that accounts for the effects of third-body layers resulting from the appli...
