SUMMARY OF FATIGUE TESTS OF FREIGHT CAR AXLES AND ESTIMATED EFFECT OF OVERLOADING

This report was prepared to accumulate and consolidate all data now available for consideration on the problem of overloading of cars in order to resolve the question as to whether the strength of axles and other car conditions justify changes in the present rules which would permit or restrict heavier loading. With a 10 percent overload, the estimated number of axles which will fail before running their full life expectancy is 72 percent. With a 20 percent overload, the estimated number of axles which will fail before running their full life expectancy is 100 percent.
