Abstract
A railroad tamping machine for tamping adjacent pairs of ties in which a pair of workheads each including a pair of tamping units associated with each of the ties can be moved vertically as a unit or independently of each other and wherein a selected set of tamping units associated with a single tie can be held in an inoperative position while the remaining tamping units work on the associated tie. In one embodiment, provision is made for adjustment of the pair of workheads laterally and longitudinally relative to the track direction to accommodate irregular rail and tie spacing as well as rail curvature such as that encountered in switch areas.
