A center plate (20) is provided for installation in a center plate pocket (21) in the underside of a railcar (10) undercarriage. The center plate (20) comprises an upper wall section (36), a lower cap section (38), and a weld area (32) between the upper wall section (36) and the lower cap section (38). When the center plate (20) is in the center plate pocket (21) the weld area (32) forms a continuous grooved perimeter which allows for the center plate (20) to be welded to the undercarriage with a single weld.
