Product Description
Westinghouse Air Brake Company (WABCO) of Wilmerding PA — the dominant railroad air-brake supplier since George Westinghouse’s original 1869 patent — allegedly manufactured and distributed composition brake shoes for AAR-standard freight car trucks (Barber, ASF Ride Control, National Swing Motion, and Buckeye designs) beginning in the postwar transition from cast-iron shoes. According to publicly filed asbestos litigation records, WABCO composition freight-car shoes allegedly used chrysotile asbestos fiber bound in a phenolic resin matrix with metallic and mineral additives to deliver the higher friction coefficient and lower wear rate that the AAR’s higher-tonnage cars required. The shoes allegedly wore rapidly in interchange service and generated visible dust at every retarder, at every hump-yard classification bowl, and along every long descending grade.
Workers Exposed
Freight-car repair yard workers at Class I hump yards (Union Pacific Bailey Yard, BN Northtown, Frisco Cherokee, MoPac DeSoto/Dupo, SP Roseville, and Conrail Selkirk) allegedly changed thousands of worn WABCO composition shoes per shift and swept up shoe dust from between the rails. Railroad car maintainers at freight-car shops (Peoria, East St. Louis, North Little Rock, Havelock NE, Beech Grove) allegedly performed the same shoe-change work on cars pulled from service. Roundhouse machinists working on locomotives coupled ahead of freight cuts allegedly encountered the same airborne fiber.
