ABSTRACT:
An apparatus for measuring the profile of a rail head includes a base, an actuating unit, a carriage and a sensing device. These components cooperate to laterally move the sensing device across the width of the rail as it is moved longitudinally along the length of the rail, so that a single sensing element may be used to measure the profile of the rail head.
