NINTH PROGRESS REPORT OF THE JOINT INVESTIGATION OF FISSURES IN RAILROAD RAILS

The information in this report of the joint investigation of fissures in rails was contained in five sections. Field tests for batter of end-hardened rails in service on the Chesapeake and Ohio Railway were performed. The summary of the batter values was tabulated. Rail ends with large cracks had approximately three times the batter of uncracked ends. Examination of end-hardened rails from the C and O test track in Carey, Ohio revealed that most damage, weeping cracks and flow of the metal over the ends and sideways, produced batter and drooping of the rail ends. Tests of mill cooling containers for rails were discussed. Examination of control-cooled and Brunorized rails which failed in service revealed that none of the control-cooled rails contained shatter cracks, but did have transverse fissures from blow holes and welded spots, horizontal split heads, detailed fractures from engine wheel burn, fatigue failures starting in the web, and detailed fractures from shelly spots. The Brunorized rails had developed transverse fissures from shatter cracks as nuclei. A comparison of drop and bend tests was summarized.
