The use of the Shaw Rail Contourograph to measure vertical wear is described and illustrated. The wide limits of specific rail wear on the British Railways and London Transport are shown as a result of corrosive influence of atmospheric pollution in tunnels and industrial areas. Annual wear is approximately proportional to the square root of the number of axles passing per annum. A comparison between the British and American rail wear values shows much lower values in America for specific wear at the same traffic intensity. This may be partly because of the higher carbon content in America where the relative humidity is above 80 percent for much fewer hours per annum, and atmospheric pollution from industry is less concentrated than in Britain. The effects of steel composition, axleload and braking on rail wear are discussed.
