MEASUREMENTS OF STRESSES IN 115 RE AND 132 RE RAIL IN CURVED TRACK, OUTSIDE JOINT BAR LIMITS

The magnitude of the measured fillet stresses for the frequency of occurrence that may be expected during the service life of the rail is less than one-half of the fatigue strength of uncorroded rail steel as determined by laboratory tests. For the curves laid with 115 RE and 132 RE rails, the diesel passenger locomotives operating at or above the balanced speed produced ranges of rail stresses that were quite moderate in value, and well within the endurance limit of uncorroded rail steel. On the curves laid with 115 RE rail, diesel passenger locomotives produced a range of stresses only slightly more than for freight car wheels, and on the curves laid with 132 RE rail the passenger diesels produced a range of stress no higher than under the freight car wheels.
