As shipment of trailers and containers by rail continues to increase, there is a growing tendency not to provide special handling, and, ultimately, complete mixed service through hump yards is desirable. For this reason the cushion arrangements to provide protection to the lading during impact are of growing importance. There is a variety of arrangements available, but until recently no direct comparison had been made by tests of cushion effectiveness. The purpose of this paper is to present this factual comparative test data, to relate this to the normal railroad operation, and to indicate cushion requirements, limitations, and related problems in moving toward unrestricted handling of piggyback and container cars.
