A railroad hopper car has a hopper carried between two trucks, and has convergent end and side slope sheets that feed a bottom discharge. The bottom discharge has a rectangular frame. The bottom discharge is lower than the center sill. The car has a flat bottom discharge having multiple arrays of louvers. All of the lading discharges through the flat bottom. The side sheets extend downwardly beyond the side sills, so that the side slope sheets terminate below the side sills. The car has laterally extending shear force transfer members that provide a shear connection between the side walls of the car. The shear force transfer members have openings to permit lading from the main containment volume of the car to pass therethough to the lading discharges. The louvers are joined to move together. Alternatively, the gate may include two opposed sliding doors separated by a beam that runs under the center sill.
A railroad hopper car having internal slope sheets, said slope sheets including a first slope sheet, said first slope sheet being perforated to define a flow through path permitting passage of lading.
A railroad hopper car having at least a first fore-and-aft oriented, internal, cross-wise extending, perforated shear force transfer member that provides a lading flow path therethrough.
A railroad hopper car comprising:
A railroad hopper car having a lading containment shell carried on railroad car trucks in rolling motion in a longitudinal direction along railroad tracks, wherein said lading containment shell includes side walls having first and second side sheets, and at least a first upwardly extending tie is mounted to said first side sheet within said lading containment shell, said upwardly extending tie having a laterally outwardly bulging profile to which said first side sheet conforms.
A railroad hopper car having a lading containment shell carried by railroad car trucks for rolling motion in a longitudinal direction along railroad tracks, wherein:
A railroad hopper car having a lading containment body having a roof opening through which to introduce lading and a bottom discharge;
