RESEARCHERS FIND CAUSES OF RAIL CORRUGATION

This article describes the experiences and study results of the Canadian Pacific Railroad into the problem of rail corrugation that has occurred in the heavy grade/heavy curve territory of Western Canada. As a result of their investigations, Canadian Pacific has proposed a five-point program as a long-range approach to elimination of the contributing factors of the defect. The program involves concentrating on the wheel-rail interface, adoption of self-steering trucks to reduce lateral forces, improvement in rail metallurgy, reexamination of the lubrication policy, and reduction in the magnitude of dynamical rail loading. The nature of corrugation is discussed in relation to its formation and the subsequent wear process. From the study results, it appears that lubricant accumulation plays a large role in the formation of rail surface fatigue. It is recommended that railroads whose traffic levels approach 40 million gross tons per year adopt the proposed five-point program.
