The invention discloses a railway grain hopper car top cover and a railway grain hopper car, and relates to the technical field of railway transportation equipment. The top cover of the railway grain hopper car comprises a top cover body, the top cover body comprises a first top cover body and a second top cover body which are arranged side by side in the width direction of the top cover body, and the first top cover body and the second top cover body are each of a hollow thin-wall box type structure extending in the length direction of the top cover body and are connected in a welded mode. The two ends of the first top cover and the second top cover are connected through end plates, and the bottoms of the first top cover and the second top cover are connected with top cover supports. According to the top cover of the railway grain hopper car, the first top cover and the second top cover are arranged to be of the hollow thin-wall box type structure, the dead weight of the top cover can be obviously reduced, meanwhile, the length of a welding seam of the top cover and the welding amount in the manufacturing process are reduced, welding deformation is reduced, and the planeness and the sealing effect of the top cover are improved.
