BEARING BRINELLING FROM COUPLING IMPACTS OF UNIT TRAIN CARS

Problems of "excessive" wear and failure have arisen in new cars in unit train service. Some were due to over-the- road running, others to rough handling of empty cars. Early and high incidence of failure of all roller bearings on a fleet of year-old unit train cars was the pessimistic prediction made for a western railroad. This paper describes their determining the cause and their solutions to this problem.
