摘要： Subassemblies for railroad tank cars are herein disclosed. In some embodiments, the subassembly includes a center sill including a generally horizontal top member and a pair of upright side plates spaced apart laterally from each other and a head brace having a lower margin welded to the top member of the center sill and an upper margin welded to the head of the tank. Each of the side plates having a top surface and an opposed bottom surface, the top surface being planar within a longitudinal central portion and at least a substantial part of a first longitudinal end portion. The bottom surface is planar and parallel to the top surface within the longitudinal central portion and a second longitudinal end portion. At least a substantial part of the bottom surface within the first longitudinal end portion has a shape that includes or approximates one or more radiuses of curvature.

摘要： Railroad hopper cars and methods of increasing total volume capacity of a railroad hopper car having a car body with two or more hoppers. In one embodiment, the railroad hopper car includes a car body having a pair of opposed sides and a pair of opposed ends defining a length. The hopper car additionally includes a pair of wheeled trucks supporting the car body. The hopper car further includes two or more spaced bulkheads extending between the pair of opposed sides to define three or more separate hoppers arranged adjacent one another along the length of the car body and between the pair of side walls. The hoppers being longitudinally asymmetric such that total volume of the hoppers on one side of a transverse center plane of the car body is different from total volume of the hoppers on the other side of the transverse center plane.

摘要： Articulated connectors are attached to and extend from center sills of adjacent car units of a multi-unit railroad freight car, connecting the car units to each other and to a shared truck. The center sill of each of the car units includes a top member that is of increased thickness at the outer end of the center sill. A weld extending along a shoulder that extends around the main body of s portion of the articulated connector attaches the articulated connector portion to the outer end of the center sill with ample strength to carry draft and buff train loads as well as the weight of the car unit and its lading, without the need for weld joints inside the center sill.

摘要： A treatment system for collecting storm water from an industrial area and removing suspended and dissolved pollutant materials from the storm water. Storm water is accumulated and delivered to a filtration apparatus in which suspended pollutants are removed by filtration, while dissolved materials, particularly heavy metals including zinc and copper, are removed by chemical chelation in a bed of compost filter media having a high humic acid content and which is kept consistently moist. A sparger provides for wide and generally uniform distribution of the storm water over the bed of filter media and provides for slow passage of the storm water through the filter bed, thus giving a long contact time of the storm water with the filter media in order to promote and enhance chemical chelation progress to chemical equilibrium and removal of a high percentage of dissolved metals, and particularly dissolved copper and zinc.

摘要： A railway tank car including a protective structure for the top of its cargo tank and surrounding a valve group mounting nozzle and a pressure relief safety valve nozzle, to protect the associated valves against damage resulting from the car being overturned, particularly while the railcar is moving along a railway. The protective structure includes an upstanding wall of metal plate that surrounds and is located at a radial distance outwardly apart from the tank top valve group mounting nozzle. A reinforcing band is attached to an upper portion of the upstanding wall to enhance its strength. Also disclosed is a method of protecting fittings mounted on a nozzle on the tank top of a railway tank car by providing and mounting such a protective structure to surround the tank top nozzle and associated fittings.

摘要： Open top gondola railcars and closure assemblies for cleanout openings of those railcars are disclosed. In some embodiments, the closure assembly includes a closure member sized to be received in a cleanout opening and to span a substantial portion of the cleanout opening to define at least one gap between a closure perimeter and a floor perimeter. The closure assembly additionally includes a sealing member fixedly attached to, or formed with, the closure member. The sealing member spans between the floor perimeter and the closure perimeter to cover the at least one gap. The closure assembly further includes a tethering member having opposed first and second end portions. The first end portion is fixedly attached to the closure member and the second end portion is attached to one of the floor or a cross bearer of the open top gondola railcar.
