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

Causes of shelly spots and head checks in rail are determined, and methods for their prevention are discussed. Two phases of the investigation include the inspection of heat treated and alloy rail service test installations on curves with shelly histories and the laboratory investigations of shelly rail involving rolling- load and slow-bend tests. The usual service test inspections are made of the fully heat-treated and alloy rail installations to corroborate the observations of previous years. Investigations featured include the service test installation of induction-hardened rail on the Great Northern Railway and on the Norfolk and Western Railway and the test installation to compare high-carbon rail with blue-end rail on the Pennsylvania Railroad. New developments in induction and flame hardening of rails to increase their resistance to shelling are also reported.
