A cover assembly is used with any one of a plurality of hopper cars each including a top side having a trough hatch therein, coaming extending around the perimeter of the trough hatch, and hinge pin brackets attached to the top side of the hopper car at one of a plurality of predetermined vertical heights relative to an upper edge of the coaming. The cover assembly permits the hatch cover to be fastened to hopper cars having hinge pin brackets provided with pin axes located at one of the plurality of heights relative to the upper edge of the coaming, and includes a hatch cover and a universal hinging system for use therewith. The hinging system includes a bracket and a plurality of hinge eye plates. Each of the plurality of hinge eye plates includes a bracket connection surface defined in a plane and an eye segment defining a opening having a central axis. The central axis of each of the plurality of hinge eye plates is displaced from the plane of the hinge eye plate by a distance different from the distance between the central axis and plane of each of the other hinge eye plates. The bracket is connectable with the cover as well as with the bracket connection surface of one of the hinge eye plates, and the hinge eye plate is connectable with hinge pin bracket with the central axis of the eye segment aligned with the pivot axis defined by the hinge pin bracket of the hopper car.
