This article explores the design of a new wheel profile which can be used in a tram-train vehicle. A tram-train is a dual-mode vehicle that operates on two very different railway infrastructures: as a tram on light rail infrastructure and as a conventional train on heavy rail infrastructure. The challenges of wheel-rail interface have been highlighted and discussed, and the analysis and design process required to develop an optimised wheel profile for dual-operation running have been presented. One of the key issues in developing a dual-operation wheel profile was managing the contact conditions within the wheel-rail interface. The interface is critical not only to the safe running of the vehicle but also to maximise asset life and to minimise wheel-rail damage. A combination of vehicle dynamic simulations and bespoke software was used to allow the development of a new wheel profile for tram-train operations.
