ABSTRACT:
A rail car door closer is provided and includes a movable base having a rotatable member rotationally disposed thereon. The movable base is coupled to a drive system configured to translate the movable base along a rail or a track disposed adjacent a railroad track rail. A device is also provided to permit securement of the rotatable member in a substantially upright position. When the rotatable member is in the substantially upright position, it is positioned vertically to contact an open rail car door and, upon movement of the movable base to a position adjacent and beneath the open rail car door, the rotatable member contacts the open rail car door and subsequently moves the open rail car door in correspondence with a movement of the movable base.
