    Patent number: 4265149
    Abstract: A tool for use in a lathe for truing railroad wheels comprises a plurality of cutting tools mounted on a common tool carriage. One of the tools is independently movable relative to the other tool or tools so that the rolling surface and wheel flange of a worn wheel may be trued in a single axial cutting stroke of the tool carriage. The arrangement is such that the movable tool is withdrawn after cutting at least a portion of the worn rolling surface, and another tool cuts the remaining defective stock of the rolling surface as well as the wheel flange.
