Abstract

Rail maintenance occurs irrespective of its performance regime. However, the scope is profile restoration in the case of wear and 'resetting' of the surface fatigue life for RCF, which is essentially different. The latter requires not only surface roughness limitations, but a properly 'tuned' surface finishing process with respect to three input energy dissipation mechanisms: removal of surface material, thermally driven transformation of remaining surface material and mechanically driven deformation of subsurface material. Fundamental research into the relationship between post-treatment surface parameters, via contact loading conditions and failure mechanisms to lifecycle performance appears crucial, with this paper discussing its basis.
