A rail maintenance vehicle includes a slide frame along which a grinder may move while the vehicle remains stationary. The grinder may be moved automatically away from the rail as the grinder moves longitudinally along the rail away from the center of a weld bead in order to smooth the grinding at the weld bead. The slide frame is connected by a linkage mechanism such that the grinder may be oriented at different grinding angles over a range of 200.degree.. The grinder is mounted upon a lateral displacer such that the grinder may be moved from one side of the vehicle to the other for grinding on rails on either the right or left side of the vehicle. A turntable system allows the turntable cylinder to pivot up and out of the way to a horizontal position so that the lateral displacer may move the grinder from one side of the vehicle to the other without interference from a vertical turntable cylinder.
