SERVICE TESTS OF DESIGNS OF MANGANESE STEEL CASTINGS IN CROSSINGS AT MCCOOK, ILLINOIS

This report covers the service performance of the solid manganese test castings in the crossings between the double-track lines of the Baltimore and Ohio Chicago Terminal Railroad and the Atchison, Topeka and Santa Fe Railway at McCook, Illinois. This solid pedestal design that was not depth hardened on the tread corners was retired after a service life of 3.60 years. This casting was removed from service because of the combined weakening effect of the cracks from the top to the bottom of the casting. On June 3, 1957, for the same defects, the solid pedestal design with depth hardening was retired after 4.44 years of service in the same crossing. Although the USS depth-hardened casting had more cracks at its retirement than the unhardened specimen, it is judged that the major portion of the increase in life for the depth-hardened one can be attributed to that treatment.
