Abstract: According to some embodiments, a railcar comprises a hopper with a sloped sheet and a discharge door. A first end of the discharge door is coupled to the railcar and pivots the discharge door between closed and open positions. The sloped sheet comprises a discharge end that is in contact with the discharge door when in the closed position. A second end of the discharge door extends beyond the discharge end of the sloped sheet when in the closed position. The discharge door comprises a lip disposed at its second end that extends generally perpendicular to the discharge door and parallel to the sloped sheet when the discharge door is in the closed position. The sloped sheet comprises a gasket coupled to its exterior portion. The lip of the discharge door contacts the gasket when in the closed position.

Abstract: Hopper cars both open and covered and discharge control systems are disclosed. Each hopper car may include at least one hopper and a center sill which defines in part a longitudinal axis of the hopper car. At least one discharge opening may be formed proximate a lower portion of each hopper. A respective door assembly may be pivotally mounted adjacent to each discharge opening to control the flow of lading from the respective discharge opening. Each discharge control system may include a common linkage and associated secondary linkages operable to move associated door assemblies between a first position and a second position. A power source including a motor, an air cylinder or a hydraulic cylinder may be disposed on the railway car to move the common linkage. For other hopper cars a wayside drive system may be releasably engaged with a capstan operable coupled to the common linkage.

Abstract: Railway cars are provided with sidewalls having an optimum number of support posts formed from a first material such as, but not limited to, steel and an optimum number of support posts formed from a second material such as, but not limited to, aluminum to optimize empty car weight and service of life of each railway car. The sidewalls may also be formed from materials such as, but not limited to, steel side sheets and aluminum side sheets.

Abstract: A railcar with discharge control system is disclosed. In one embodiment, a railway car includes an underframe and at least one hopper for transporting lading. The railway car further including the underframe including a center sill which defines in part a longitudinal axis of the railway car. A discharge opening formed proximate to a lower portion of the hopper. A respective door assembly pivotally mounted adjacent to the discharge opening to control the flow of lading from the hopper. The door assembly operable for movement between a first, closed position and a second, open position relative to the discharge opening. A discharge control system operable to move the door assembly between the first position and the second position. The discharge control system operably moves generally longitudinally along the axis of the railway car to move the door assemblies between the first, closed position and the second, open position.

Abstract: A safety latch lock indicator for a railcar door operation mechanism is disclosed. In one aspect, the present invention teaches a railway car having an underframe and at least one hopper for transporting lading. The underframe including a center sill which defines in part a longitudinal axis of the railway car. A respective door assembly mounted adjacent to the discharge opening formed proximate to a lower portion of the hopper to control the flow of lading from the hopper. The door assembly moves via the discharge control system between a first and second position relative to the discharge opening. An indicator may extend from a side of the railway car as the door assembly moves between the first and second positions, wherein a portion of the indicator becomes visible from at least one side of the railway car.

Abstract: A boxcar and load restraint system are provided with improved load carrying capabilities and performance characteristics of uninsulated boxcars and insulated boxcars. An insulated boxcar with the load restraint system may have increased load carrying capacity, increased service life, and reduced maintenance costs as compared to conventional insulated boxcars. All or portions of the load restraint system may be used in uninsulated boxcars.

Abstract: A universal boxcar is provided with exterior metal surfaces and load carrying capabilities of a conventional uninsulated boxcar and thermal transfer ratings of an insulated boxcar. The boxcar may be formed with interior dimensions corresponding generally with interior dimensions of an uninsulated boxcar without high cost, high performance insulation. The boxcar may include a double side doors slidably mounted on the exterior of each sidewall assemble. A load restraint system may be provided with improved load carrying capabilities and performance characteristics. The load restraint system may have increased load carrying capacity, increased service life, and reduced maintenance costs. All or portions of the load restraint system may be used in uninsulated boxcars or temperature controlled railway cars.

Abstract: A railcar with longitudinal discharge openings is disclosed. In one embodiment, the railcar includes an underframe, a pair of sidewall assemblies and a hopper formed between the sidewall assemblies. The underframe has a center sill and a pair of side sills. The center sill disposed between the pair of side sills along a generally longitudinally axis of the railcar. The hopper includes a discharge opening adjacent to the center sill. A respective discharge door assembly disposed adjacent to each discharge opening to control flow of lading from each hopper. Each discharge door may hinge from the center sill for movement between a first position and a second position relative to the discharge openings.
