Disclosed is a trackside operating mechanism for use with a railway hopper car having a longitudinally extending discharge door hingedly mounted on the car for movement laterally outwardly from closed to open position relative to a discharge opening thereof. The trackside operating mechanism includes a base positioned to one side of a railway track, an upright pedestal mounted on the base, a horizontal arm pivotally mounted on the base for swinging movement on a vertical axis, wheel means including a pair of wheels longitudinally spaced on the arm for pivotal movement about a respective vertical axis. Means are connected to one wheel for imparting rotation of this wheel to the other wheel, the wheel means being positioned to engage the side of an open door of a hopper car traveling along the track beside the trackside operating mechanism for thereby swinging the door inwardly toward the car to a closed position.
