Undulatory wear on corrugation in rails is universally considered to be of two main types: roaring rails or washboard track; and what is sometimes described as saddles. The majority of railways consider that speed has no relationship with corrugations. Undulatory wear appears from 3 to 12 months after laying. The general opinion is that braking decreases washboarding but increases saddles. In the U.S.A. experiments with an acetylene torch to temper the Martensitic area of the high polished spots of washboard corrugations caused the ridges in the track to disappear. Various methods of grinding have been tried, but none have proved permanently successful.
