oa Civil Engineering = Siviele Ingenieurswese - Temperature and wear of rails on railway track
In this article, the author attempts to describe the wear mechanism in the interface between the wheel flanges running against the side of the rail crown when a railway wagon rounds a curve in a railway line. The cost of aggressive wear in the rail-wheel interface is compared to the cost of lubrication of the railway track and methods of lubricating the rail-wheel interface are described briefly. The trajectory of points on the wheel flange against the side of the rail is described and the effect of aggressive wear between the surfaces shown. The results of measurements of rail temperatures in the wear interface are discussed, as well as the frequency of occurrence of hot wheels on the Richards Bay coal export line
