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

The investigation into the causes of shelly spots and head checks in rail surfaces was presented. A definition and description of shelly spots, the most serious type of rail damage, was presented. The division of the work of this subcommittee was described. Appendix A presented the shelly rail studies conducted at the University of Illinois. Laboratory studies of failed shelly rails concluded that shelling appears to be the result of cold working of the rail steel by "line contact" with car wheels. The presence of imperfections accelerated the formation of cracks. Laboratory rolling-load tests to produce shelling were performed. Different rail steel compositions were studied through rolling-load tests. The Brinell hardness of the wheel path after rolling was measured. Full sections specimens of heat-treated carbon rail were tested under rolling-load. No conclusions were reached.
