Rail wheel measurement
First Claim
1. A method of determining a remaining service life for a rail wheel of a railway vehicle using an electronic rail wheel wear gauge mountable on a rail wheel for measuring at least one rail wheel dimension, the method comprising:
- measuring a rail wheel dimension;
processing the measured wheel dimension relative to an allowable wear dimension;
accessing a historical wheel wear rate database 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.

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.

15. A method of determining a remaining service life for a rail wheel of a railway vehicle having an annular reference groove formed in a face of the wheel using an electronic rail wheel wear gauge for the rail wheel, the method comprising:
-
identifying a reference groove dimension indicative of a diameter of the reference groove of a rail wheel being measured;
measuring a rail wheel dimension of the rail wheel relative to the reference groove; and
determining a rail wheel diameter of the rail wheel based on the received reference groove dimension and a measured rail wheel dimension.

18. A method of verifying a need to service a wheel removed from a railway mobile asset and identified by an identifier using an electronic rail wheel wear gauge mountable on a rail wheel for measuring at least one rail wheel dimension, the method comprising:
-
measuring a rail wheel dimension of a wheel removed from a railway mobile asset;
processing the measured wheel dimension relative to an allowable dimension to determine if the wheel needs to be serviced; and
associating the rail wheel with an identifier to link the wheel to a locomotive from which the wheel was removed for tracking service and operational history of the rail wheel.
