WebDec 16, 2024 · Step (b) Corrugated rail: After the first wheel passages on the smooth rail, the initial corrugation of (2A max) 0 will develop and is thus applied to the rail surface. It is proportional to and in antiphase with the initial differential wear. Antiphase means a wear peak causes a corrugation trough. WebRail corrugation is a kind of periodic wear on the rail running surface. For metro lines, the corrugation phenomenon of small radius curve section is more common, and the corrugation wavelength is mainly concentrated in the range of 20 ~ 100 mm, which belongs to the short-pitch corrugation [1,2].
