摘要： According to some embodiments, a railcar comprises at least two hoppers for transporting a commodity. Each hopper comprises a pair of side walls and a floor. The railcar further comprises a composite partition separating the hoppers. The composite partition comprises a frame comprising a first material coupled to the pair of side walls and the floor at a location separating hoppers. The frame comprises a center opening. The frame is configured to provide structural support for structural loads exerted on the pair of side walls and the floor. The composite partition further comprises a composite section comprising a second material coupled to the frame and covering the central opening of the frame. The composite section is configured to withstand loads exerted on the composite section by the commodity transported in the hoppers.

摘要： According to some embodiments, a refrigerated railcar comprises a pair of side walls, a roof, a floor, and a refrigeration unit. The floor comprises a bottom structure comprising a plurality of channels for return air flow from an interior of the railcar to the refrigeration unit. The floor further comprises at least two top plates coupled to the bottom structure (e.g., via a pivot rod). Each of the top plates extends longitudinally along the bottom structure and is configured to rotate up and away from the bottom structure proximate one of the side walls of the pair of side walls. Lifting an edge of a top plate opposite the edge of the top plate pivotally coupled to the bottom structure causes the top plate to rotate to an upright position exposing the plurality of channels of the bottom structure.
