A rail adjuster has a frame which mounts a head assembly for powered vertical movement between a raised travel position and a lowered operative position, with the head assembly having adjuster arms which can be positioned immediately adjacent a pair of rail-mounted anchors. The adjuster arms are moved together to shift the rail-mounted anchors along the rail toward the tie to achieve the anchor adjusting. The adjuster arms are constructed in a pivoting linkage having a horizontally acting hydraulic cylinder to provided a substantially horizontal force to the adjuster arms for providing an enhanced mechanical advantage in adjusting the anchors.
