摘要： A railcar system that includes a railcar with a discharge opening and a longitudinal gate positioned adjacent to the discharge opening. The system further includes a driving system connected to the longitudinal gate that is configured to move the longitudinal gate between a closed position and an open position. The system further includes a controller connected to the driving system that causes the driving system to position the longitudinal gate in the closed position, position the longitudinal gate in the open position, and position the longitudinal gate to remain an at least partially open position. The longitudinal gate is less than fully open when the longitudinal gate is in the at least partially open position.

摘要： 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.
