Summary: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.
