EVALUATION OF CUSHIONED UNDERFRAMES

This report is an evaluation of cushioned underframes, which indicates that protection of commodities shipped is related not only to draft gear but to loading methods and packaging. Impact tests used include tests of special cushioning devices with travel to 24 inches. As a result, the sliding sill cushioning device provided most protection to lading, the hydraulic draft gear provided most protection to the car underframe.
