ROAD AND LABORATORY INVESTIGATION OF TRUCK BOLSTERS FOR UNIT TRAIN CARS

Problems of "excessive" wear and failure have arisen in new cars in unit train service, some due to over-the-road running, others to handling of light cars. Similar problems can arise in trains of non-uniform, but regularly assigned, car types in continuous high-mileage, high speed, rapid turnaround service. Railroad cars permanently assigned to unit train service travel many more miles yearly than cars in conventional freight service. At terminals their loading and unloading is expedited to reduce turnaround time. Consequently, the load spectrum that a conventional-service car would encounter over years, is compressed, for the unit train car, into a much shorter time interval. This paper describes the experiences with truck bolsters from a coal-hauling fleet of unit train cars.
