Abstract
A machine for removing old rails and replacing them with new rails is constituted by an adzing station where the surfaces of the old ties are adzed after removing the old rails and tie plates. The adzing station has two adzers spaced laterally on either side of the center of the machine for adzing laterally spaced locations at which new tie plates and rails have to be laid. The adzers are mounted, respectively, on two frames which can move together laterally with respect to a third frame in response to a center line follower so that the adzers are always located at the correct lateral position even on curved track. The third frame is attached to the main frame of the machine and it can be pivoted selectively about two spaced lateral locations adjacent to where the adzers are mounted in response to control signals from an inclinometer mounted on the pivotal frame and control signals from a superelevation device measuring the superelevation of the track. Thus the adzers are maintained substantially perpendicular to the ties for all conditions of cross-level including superelevation on curves.
