RECENT DEVELOPMENTS AFFECTING RAIL SECTION

This report presented two studies in corrosion fatigue of rail web steel. Two fatigue tests with corrosion using tap water as the corrosion medium were performed. Tests from the University of Illinois showed very little reduction in the endurance limit as obtained without corrosion. Duplicate tests performed at the Pennsylvania Railroad Laboratory at Altoona, Pa. resulted in a greater reduction in the endurance limit than that of the original at the University of Illinois. It was concluded that the Altoona tap water was more corrosive than the Urbana tap water which accounted for the difference of results, and therefore,, no further modification of the corrosion procedure was done. Results of the Altoona test could readily be interpreted as corrosion fatigue due to the severity of the corrosion present during the tests. A curve concluded fatigue with and without corrosion was present. It showed that where corrosion is present it becomes a practical impossibility to so design a rail and the rail joint as to prevent failure from corrosion fatigue. In summary it was felt that sufficient proof had been offered that rail web failures in the joint do occur from corrosion fatigue, and that the fatigue life of rail web steel can be sufficiently reduced by corrosion fatigue to account for these failures.
