Completed by the Health and Safety Executive (HSE) Labs, the work was reported under the Phase 1 ORR study document, entitled `A survey of UK tram and light railway systems relating to the wheel/rail interface' ~'~. Phase 2 of the work, presented within this report, analyses this initial study and extends the work through the application of wheel-rail contact analysis techniques and railway vehicle dynamics modelling to determine optimised wheel and rail profile combinations which minimise derailment risk and wear.
