EFFECT ON RAIL OF KERSHAW TRACK LINER

Since this is the first track lining machine to operate on an impact principle, some question of doubt had been raised as to the possible effects of this impact on the rail under adverse conditions. As a practical test the machine was first used at a temperature of plus 30 degrees F. on curved yard track laid with 1903 100-lb. rail. It was used in attempting to line a yard track laid with 85-lb. rail with a rail temperature of plus 10 degrees F. an atmospheric temperature of approximately 0 degree F. In both cases the track was full of cinder ballast, frozen solid. Ties were spaced 23 inches apart and were in good condition. In the practical test the Mershaw Track Liner did not break or visibly kink either 85-lb. or 100-lb. rail under the very adverse conditions of the test. However, the track structure was weakened and track gauge spread 1/12 in. after five to eight impacts of the ram.
