ABSTRACT:
A strobe light, oriented directly over a railroad track rail and at a 45.degree. angle to the horizontal, projects a light line across the rail. A pair of cameras oriented directly over the rail view the light image on the rail. The light lines reflected from the foot of the rail provide a reference for numerically describing the profile of the railhead. The measured rail profile is compared to an ideal rail profile. The results of the comparison are used to position grinding modules for grinding the rail to a preferred profile.
