Abstract

A device for in-situ, dynamic repair of a railroad can include two connected machines. A first one of machines can be a track lifting unit that can clamp the rails of the railroad and lift the track in its entirety out of its track bed. The first machine also can plow ballast away from and/or toward the rails, and level the track bed for the rails before they are lowered. In addition, the track lifting unit can remove selected railroad ties. The second machine can include a power unit that can provide hydraulic, pneumatic and electrical power to both machines. The power unit also can provide track stabilization by settling ballast and can free debris from the railroad while it is raised.
