This report presents the procedure used in determining the annual cost of various rail types in curved track on a specific railroad's conditions. The procedure is based on evaluating wear profiles, taken in track, of the several rail types under various conditions. The rail types examined were: heat treated, high-silicon, induction hardened, flame hardened, and plain rail of both 115 lb and 132 lb sections. The initial step was to determine wear rates for the various rail types and curvature conditions. From these wear rates it was possible to determine the life of the rails and the resultant annual costs. The report contains a brief review of previous research in this area.
