A wheel for use on rail tracks, the wheel comprising a frame 1 which supports a plurality of rollers or ball bearings for providing a bearing surface on the side of a rail. This can reduce wear on railway or tramway rails and wheels by eliminating the metal to metal sliding when wheel flanges come into contact with the rail. The frame may be made of two or more sections so that it is removable from the wheel for maintenance. The rollers may be tapered or truncated cone shaped and may be mounted at an angle and offset from the edge of the wheel. The wheel may also have an outer ring section on each frame part for ensuring the balls remain attached during the event of bearing failure.
