Abstract: An articulated multi-unit railway hopper car including a pair of end units having couplers mounted on their outboard ends. A plurality of intermediate units are interconnected between said end units. A plurality of articulated connector assemblies interconnect the end units and the intermediate units. A pair of side bearing housings are mounted on each side of the articulated connector assemblies. A body side bearing extension arm assembly is disposed in bearing relationship with each of the side bearing housings and connects two ends of adjacent units. Torsion boxes extend substantially the width of the inboard ends of the end units and the opposed ends of the intermediate units and carry the upper bolster unit and are connected to the body side bearing extension arm assemblies.

Abstract: A center beam/center partition flat car, cable/strap retention assembly and method for retaining a load to a center beam/center partition flat car. Cables or straps are respectively retained to a plurality of winches positioned along the opposite side sills of the flat cars. The cables or straps extend around the load from bottom to top and downward with their free ends being secured to the floor deck of the flat car at a position adjacent the respective winches.

Abstract: A railway flat car having a depressed load carrying portion to reduce the center of gravity of the car. The flat car includes a side sill assembly having upper end section having floor portions and a lower intermediate section for supporting the depressed load carrying portion. The depressed portion is formed with an overall width less than the upper floor portions. The car is provided with an intermediate longitudinal center sill that merges with end draft sills having a larger width than the center sill.

Abstract: A trough hatch cover system employing one or more cover units pivotally mounted on a hopper car by hinge straps. The one or more cover units are formed with a corrugated panel having an end extrusion mounted at each end. The end extrusion strengthens the panel structure and provides a channel through which water collected on the corrugated panel can be drained. Closure members are used to secure the cover units in place and when closed create sealed contact with the end extrusions, whether at the ends of the hatch cover system or at the juncture between adjacent panels.
