Abstract: The invention relates to transport engineering, in particular to railway transportation vehicle wheels. Essence of invention: A railway wheel having a central plane perpendicular to an axis of rotation of the wheel which includes a rim formed by a tread surface and a flange, and also includes a hub and a web formed by external and internal surfaces and made in such a way that a theoretical midline of a transverse web profile passes through a first point located in a place of matching the web with the rim, a central point where the theoretical midline has maximum offset from the central plane in a direction opposite to the flange, and a second point located in a place of matching the web with the hub, wherein the external and internal surfaces of the web are formed by external and internal radius curves, respectively, wherein radiuses of the first and the second external radius curves for the external web surface are from 0.04 to 0.
