Out of 30,881 failures of new rails in U.S.A. tracks in 1942-51, and removed during that period because of defects, 13,554, or 44 percent, were web failures. The great majority of the latter were failures within the area of the rail joint. Laboratory and track tests showed that many web failures could be explained by corrosion-fatigue but not by corrosion alone. Various factors increase the web stresses at rail ends. One is poor or irregular fit of fishplates; loose or worn fishplates or loose fishbolts have a bad effect, as they are liable to cause greater impacts to develop under the rolling load. Excessive gaps at the rail-joints or battered rail ends similarly tend to increased impacts.
