INVESTIGATE CAUSES OF SHELLY SPOTS AND HEAD CHECKS IN RAIL SURFACES FOR THE PURPOSE OF DEVELOPING MEASURES FOR THEIR PREVENTION

Causes of shelly spots and head checks in rail surfaces are investigated to develop measures for their prevention. Topics discussed include study of rail steel compositions, heat treatments, wheel and rail contacts and pressures, mill practices, and consideration of larger diameter wheels or lighter loads on the wheels. It is cautioned that new chemistry or heat treatment may induce other types of defects or excessive expense. Study of shelling reveals no definite trend or definite conclusions. It is noted that the control cooled process will not prevent shelling. Rolling load machines and tests are discussed.
