SERVICE TESTS OF DESIGNS OF MANGANESE-STEEL CASTINGS IN CROSSINGS AT MC COOK, ILL

This report covers the service test of the last remaining test casting in the double-track lines of the Baltimore & Ohio Chicago Terminal Railroad and the Atchison, Topeka & Santa Fe Railway at Mc Cook, Ill. The two U. S. Steel solid pedestal castings showed that the depth-hardened frog was in service 0.8 year longer and carried 56 million more gross tons of traffic than the unhardened casting. Both depth-hardened castings were in service 26 months before the first welding of the battered tread corners a compared to the 18 months for the USS unhardened casting. The greater service life of the Rampo deepened-flangeway design than that of the USS solid pedestal type castings indicates some advantages for the more flexible casting. The USS casting with rigid support of tread corners also developed the higher receiving flangeway fillet stresses. All of the test castings were those used in the end position with a height of 6 1/4 inches to match 110 RE rail and an intersection angle of 75 degrees 48 minutes.
