Wheel/rail interaction: current "state of the art" in the Australasian Railway Industry

Railway systems have benefited from the development of improved wheel and rail profiles that improve vehicle-track interaction behaviour and hence reduce the damaging effects of wear and rolling contact fatigue, particularly under more extreme operating environments. When combined with the use of higher-strength wheel and rail materials and improved wheel-rail lubrication practices, these developments have contributed to increases in wheel and rail lives, and facilitated higher axle load limits in major mineral haulage systems. The extent to which wheel-rail interaction behaviour can be improved or optimised in practice (compared with that predicted by a theoretical or analytical approach) is, however, constrained by several factors including: a range of vehicle types and operating speeds in multi-user systems; the extent to which owners and operators of such systems agree to implement modified profiles and the associated maintenance practices; the ability of rail grinding machines (and their operators) to implement and maintain modified rail profiles; and the extent to which changes in vehicle-track interaction characteristics may affect defect characteristics in rails (or wheels) of variable metallurgical quality.
