Influence of rail flexibility in a wheel/rail wear prediction model
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2016 The aim of this paper is to study the influence of rail flexibility when a wheel/rail wear prediction model that computes the material loss based on an energy approach is used. The wheel/rail wear model used in this investigation is a simplified combined wear hypothesis that is based on the frictional energy loss in the contact patch.

WEAR RATES IN URBAN RAIL SYSTEMS [PDF]
WIT Transactions on The Built Environment, 2017 A significant part of maintenance costs in urban rail systems (metro, tram, light rapid transit/light metro) is due to wheel-rail wear. Wear rates - measured for example as depth of wear per kilometre run (rolling stock) or per train passage (rails) - depend in a complex manner on several influence factors.
