1. A cast steel railway wheel comprising: a hub having an axial bore; a rim concentric with the bore; and a plate extending radially from the hub to the rim, the plate having a front face and a rear face, the plate having a plurality of spokes extending between the hub and the rim, adjacent spokes having different thicknesses defined between the front face and the rear face, wherein the rear face of the plate is discontinous and defined by a series of ridges and voids defining corresponding spokes, and wherein the spokes have hub ends and rim ends, the spokes comprise a series of circumferentially positioned and alternating major and minor spokes, the thicknesses of the minor spokes at the hub ends being less than the thicknesses of the major spokes at the hub ends, the thicknesses of the minor spokes at the rim ends being equal to the thicknesses of the major spokes at the rim ends, and the thickness of the major spokes decreases along a radial length from the hub to the rim, and the thickness of the inner spokes is generally constant along a radial length from the hub to the rim.
