REPORT ON SERVICE TEST OF SOLID MANGANESE CROSSINGS FROGS AT MCCOOK, ILLINOIS

Service tests of solid manganese crossing frogs at McCook, Illinois, are reported. Stress measurements are covered in the flangeways and at other significant stress areas of five different designs of manganese castings placed in the crossings of the Baltimore & Ohio Chicago Terminal Railroad and the Atchinson, Topeka & Santa Fe Railway. Service tests include tests of the original design of casting by Taylor-Wharton and the Carnegie-Illinois casting. It is concluded that some of the designs included in the tests are more resistant to the development of fatigue cracks than others, but in none were the developed stresses low enough relative to the fatigue strength of the manganese steel to give the service life under heavy traffic that should be expected, and efforts to further reduce these stresses are recommended.
