The invention discloses a dual-purpose hopper wagon, and belongs to the technical field of railway wagons. The dual-purpose hopper wagon comprises a movable end wall, a movable connecting mechanism, a clamping device, a bottom door opening and closing mechanism and a fixed lock, wherein the movable end wall is connected to a chassis of the hopper wagon through the movable connecting mechanism, and the movable end wall can be turned to be placed vertically or horizontally. When the hopper wagon is used for carrying and transporting free-flowing goods, the movable end wall is vertically placed and can be locked in the vertical position through the clamping device, and the bottom door opening and closing mechanism is used for opening and closing a bottom door of the hopper wagon. When the hopper wagon is used for carrying and transporting a container, the movable end wall is horizontally placed, and the fixed lock is used for locking the container. The hopper wagon can be used for carrying and transporting the free-flowing goods and the container, and therefore the utilization rate of the wagon is improved, and the transportation cost is reduced.
