LIGHTWEIGHT PASSENGER STOCK DEVELOPMENT IN U.S.A.

A prototype stainless-steel passenger car, the Pioneer III, which meets all the strength and safety requirements of the Association of American Railroads, with a net weight of 595 lb. per passenger, has been designed by the Budd Company, Philadelphia. A feature is the lightweight four-wheel bogie with single air spring on each side, with tubular axles, and outside-mounted disc brakes. The basic design is suitable for both suburban and main line stock. The principal parts of the bogie are the side frames, bolster, and two air springs; there are no equalizer beams, springs, swing hangers, spring plank, or transom. Interior partitions are of micarta-faced plywood which is resistant to wear. Use is also made of laminated plastics for doors, vestibule ceiling panels, exterior door inner panels, air ducts, enclosure aroung the air conditioning, and seating.
