  • Rail wheel measurement
    Publication number: 20070043486
    Abstract: A method of determining a remaining service life for a rail wheel (18) of a railway vehicle using an electronic rail wheel (18) wear gauge (10) mountable on the rail wheel for measuring at least one rail wheel dimension. The method includes measuring a rail wheel dimension and processing the measured wheel dimension relative to an allowable wear dimension. The method also includes accessing a historical wheel wear rate database (44) relating to the rail wheel and predicting a remaining service life of the wheel based on the historical wheel wear rate data and the processed wheel dimension.
