Abstract: A system and method of continuously measuring the profile of a rail in real time is disclosed. The rail which the profile is obtained in position on a track bed, The system includes a means for transmitting a beam of light at a selected wavelength onto the rail to illuminate a portion of the rail. The light is preferably a beam of laser light. A digital image of said illuminated portion of said rail is recorded. The digital image is manipulated to filter all light except for the selected wavelength. Rail wear is determined from the digital image created by the selected wavelength of light.
