The formation of periodic wear patterns on the running surface of the rail has been observed for more than a hundred years. These wear patterns are the reason for unwelcome effects like noise and damage to the track. A high number of publications was concerned with the problem and most rail corrugation types can be explained to date [3]. Only the mechanism which leads to so‐called short pitch corrugation is not understood yet. Therefore, based on previous work ([2], [5]) a linear wheel‐track model has been developed to understand the formation of short pitch corrugation on tangent track. Numerical simulations have been undertaken with this model to analyse the corrugation process. Based on numerical results it is tried to explain why the corrugation pitch observed in practice varies little with train speed and it is shown how wheel‐rail parameters influence the proneness to corrugation.
