摘要： A railway hopper car (200) includes a filament wound fiberglass car body having side walls (202, 204) integral with a roof (208), preferably also formed of a filament wound fiberglass. The fiberglass side walls are connected to longitudinally extending side sills (220, 222) preferably made of steel which extend along each side of the car. The car body includes laterally spaced top sills (226) preferably of fiberglass connected to the fiberglass sides. The car is divided into a plurality of hoppers by transverse bulkheads (244, 246, 248) which are conveniently formed of sandwich panels of wood or wood fibers with fiberglass facings. Hopper slope sheets (258, 260, 262, 264, 266, 268) and end slope sheets (304, 306) are also conveniently formed of sandwich panels of wood or wood fibers with fiberglass facings. Metallic stub sills (282) are located at each end of the car and a metallic shear plate (292) at each end of the car extends transversely of the car to transfer coupler loads from the stub sill to the side sills. The fiberglass body is cut away at lower end portions (340) to avoid direct engagement of the car body with the stub sill and the shear plate. The coupler loads are transferred through the shear plate (292) to the side sills (220, 222) and direct loading of the fiberglass car body with coupler loads is substantially reduced.
