CAUSES OF SHELLY SPOTS AND HEAD CHECKS IN RAIL METHODS FOR THEIR PREVENTION

Continuing investigations confirmed that heat-treated or alloy rails were effective in extending the service interval before gage corner shelling occurs in track. A description and summary of eight test installations of heat-treated and alloy rails in areas of high shelling was presented. Appendix 8-a presented the progress of shelly rail studies. Rolling-load tests of high-silicon rails and one chrome-vanadium rail were performed. Shelly rail failures from service were examined and rolling-load tests to produce detail fractures in the laboratory were performed. Detail fractures from shelling in European rails were discussed. High-silicon rails gave rolling-load tests 50 to 100 percent better than standard carbon-steel rails before developing shelling failures. Three tests of a chrome-vanadium alloy rail gave two tests over 5,000,000 cycles and one test of 1,846,000 cycles. Rolling-load tests of high-silicon rails to develop detail fractures from shelling produce failures similar to those produced in track.
