A railroad car body has a longitudinally extending center sill, and a main bolster extending transversely relative to the center sill. A center plate is mounted under the center sill at the intersection of the center sill and the main bolster. The center plate seats in the center plate bowl of a truck that supports the rail road car body for rolling motion along the rail road tracks. The center plate is a casting that has a round peripheral wall that seats entirely within the center plate bowl. None of the center plate extends beyond the round peripheral wall, and none of the center plate overhangs the peripheral upstanding steel ring of the center plate bowl wall. The center plate has a continuous circumferential welding fillet relief such as may tend more easily to permit automated welding. The center plate has a hollow, upstanding truncated central cone member for accommodating a king pin. The truncated cone stands taller than the rim. A keying fitting is mounted adjacent to the central cone to discourage angular mis- orientation of the lateral center plate edge reliefs.
