The invention discloses a vehicle body chassis and a rail wagon, and belongs to the technical field of rail wagons. The vehicle body chassis comprises a plane steel plate assembly, a middle beam, a supporting beam assembly, two side beams and a plurality of reinforcing beams. The two side beams are arranged at the two ends of the supporting beam assembly respectively. The first ends of the multiple reinforcing beams are fixedly connected with the plane steel plate assembly, and the second ends of the multiple reinforcing beams are fixedly connected with the supporting beam assembly. The middle beam penetrates through the supporting beam assembly and is fixedly connected with the multiple reinforcing beams. The vehicle body chassis and the railway wagon can bear large concentrated load per unit area, the surface flatness of the floor is guaranteed, the service life is guaranteed, and the maintenance cost is reduced.
