Abstract:
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.
