Abstract
A covered, dual hopper car made by converting a rail car having three or more covered hoppers suitable for carrying a large volume of a relatively low density commodity, to a car having a fewer number of hoppers suitable for carrying a smaller volume of a higher density commodity. This is done by internally bracing an interior portion of one end of one hopper end section; severing an unwanted center hopper section from two end hopper sections; removing the unwanted section; and then reassembling and welding the free end sections to each other. The vertical cutting and welding is horizontally offset at the side plate and the sill to provide tab and notch locking arrangements for reinforcement. Preferably, the roof loading hatches are also modified to include downwardly extending collar portions which limit the maximum loading height within the hoppers.
