SD-45 LOCOMOTIVE DYNAMIC BRAKE TRAIN HANDLING TESTS ON PENNSYLVANIA RAILROAD

Because of a major derailment near Johnstown, Pa., a series of dynamics brake handling tests were conducted between Harrisburgh and Pittsburgh, on severe grades and curves. The trains in which the test unit and the adjacent long overhang boxcar operated were varied in nature, ranging from tonnage trains while operating in a two-unit consist to trailer trains and PR trains in four- and eight-unit consists. In general, with the loaded long overhang boxcar leading the train, the records indicate that at no time did the danger of derailing due to drawbar forces exist. No instances in the entire test program exhibited lateral force levels which would be of concern with respect to derailment. The boxcar was loaded with freight during all of the tests.
