A railway wheel (10) for a vehicle comprises a rotation axis (11') and a supporting disk (11) which can be keyed or otherwise attachable on an axle at the rotation axis (11'). The supporting disk (11) can be coupled with a wheel rim (13) intended for rolling on a rail. The wheel (10) provides damping means (20) of the wheel rim (13) with respect to the supporting disk (11) which comprise a plurality of elastic elements (25) interposed between the supporting disk (11) and the wheel rim (13), aside with respect to the median plane (10') of the wheel. Each elastic element (25) has its own geometrical axis (26) and comprises a first face (25a) facing the median plane (10') of the wheel (10) and a second face (25b) opposed to the first face (25a) and facing the opposite part with respect the median plane (10') of the wheel, so that the elastic element (25) extends its thickness between the two faces (25a, 25b). The first face (25a) and the second face (25b) of each elastic element (25) have the same concavity or the same convexity when considered in cross section in any plane containing said geometrical axis (26). The elastic elements (25) are designed to obtain the effective damping of any stress transmitted from the wheel motion on the rail, and to increase the lifetime of the elastic element (25) itself.
