A dual-purpose railway hopper car is constructed so that it is capable of holding, handling and hauling both coal and fly ash on different trips by virtue of having a plurality of quick opening hopper doors which are sealed to prevent leakage of fly ash when closed, highly sloping active walls, a covered top with a wide longitudinal hatch for loading coal, which wide hatch carries a smaller circular hatch for pneumatically loading fly ash. The coal hatch is operated by air cylinders from a quick connect coupling at ground level. A center sill covers the hopper door operating linkage.

A gondola tub type railway car having an arrangement for transferring payloads from the car side panels more directly to the bolsters. The car at each end has a lower bolster for support by a car truck, and an upper bolster secured to the lower bolster preferably through a shear plate. A center plate unit extends upwardly from the lower bolster into the upper bolster and is secured to the latter. The car, at each end, is provided with a reaction beam located inboard of the associated bolster, and is secured to the shear plate and to side members, and cooperates with the bolster in resisting the couple created by draft and buff forces acting in offset relation to the plane of the shear plate.
