摘要： A railroad hopper car discharge gate assembly has first and second elements arranged in vertically stacked relationship relative to each other for controlling discharge of material from a hopper car. First and second drive mechanisms move the first and second elements, respectively, between closed and open positions. A lock assembly including first and second locks serve to maintain the first and second elements, respectively, in a closed position. The gate assembly also includes a mechanical system for positively removing the first and second locks from a locked condition relative to their respective element upon rotation of either drive mechanism. A method for controlling discharge of material through an opening defined by the railroad hopper discharge gate assembly is also provided.

摘要： A door operating assembly for a railcar includes an actuating device. The railcar includes a railcar container and a lower portion coupled to the railcar container. The railcar container includes two opposing sidewalls and at least one door coupled to the lower portion. The railcar defines a longitudinal axis extending therethrough. The door operating assembly also includes at least one door operating mechanism coupled to the actuating device. At least a portion of the at least one door operating mechanism extends longitudinally along one sidewall of the two opposing sidewalls. The door operating assembly further includes at least one axial drive member coupled to the at least one door operating mechanism. The door operating assembly also includes at least one door drive assembly coupled to the at least one axial drive member. The at least one door drive assembly is coupled to the at least one door.
