1. A rail wheel, comprising:

  • a wheel hub and a wheel rim;

    a wheel disc which connects the wheel hub and the wheel rim, each of the wheel hub and the wheel rim including outer sides adjacent the wheel disc, the wheel disc including a central radial zone in which the wheel disc has a thickness which decreases from the wheel hub to the wheel rim, the wheel disc further including an inner transition zone adjacent the wheel hub and an outer transition zone adjacent the wheel rim, outer sides of the wheel disc in the inner and outer transition zones presenting curved surface configurations which merge tangentially into respective ones of the outer sides of the wheel hub and the wheel rim adjacent the wheel disc, said curved surface configurations being defined by compound curves determined geometrically by radially extending generatrices, a surface configuration of outer sides of the wheel disc in the central radial zone being determined geometrically by radially extending straight generatrices which intersect one another on the wheel rim in the outer transition zone between the curved surface configurations of the outer sides adjacent the wheel rim.
