According to present knowledge, the contact fatigue failures of rails, referred to as shelling, most frequently appear on the inner side of high rail in curves of moderate radii. In order to improve the understanding of the failure mechanism the studies on the several related research subjects are necessary, among them the laboratory fatigue tests. This paper presents two methods for physical simulation of rail contact loading in curves of moderate radii using a contact fatigue machine. The description of methods is followed by the estimation of the available range of parameters influencing contact forces on the machine, a theory of contact forces occurring on the machine and by comparison between forces generated by a rail vehicle on curved track and the loading on the machine for one and two-point contact between wheel and rail on curve.
