CORROSION RESEARCH LABORATORIES—7: Corrosion Work by British Railways Research Department

British Railways operate under conditions which include some of the most severely corrosive in the country. The steam locomotive is, of course, largely responsible for this, and the atmosphere of stations is generally moisture‐laden and polluted with sulphur dioxide and dirt. In coastal areas, sea‐spray is also encountered, and the combination of coal smoke, salt and moisture can be exceptionally aggressive. It is thus inevitable that the railways should be constantly confronted with problems of corrosion and its prevention, and the following is an account of how some of these problems are tackled.
