摘要： The invention provides for renovation of railroad track installations through the use of a sliding shield driver (9) which in the work area secures the trench (6) formed by the removal of the old track foundation and, as the renovation work advances, travels in the direction of the old track to be renovated. The sliding shield driver (9) has lateral shields (15) securing the trench walls as well as ground shields (13) resting on the trench bottom; these shields are linked to the base frame (10) of the shield driver via hydraulic shield cylinders. Preferably, the shield driver consists of a header frame and a trailer frame with trailer shields (20) pivotably attached to the lateral shields (15) at the trailer frame (19). The lateral shields with the trailer shields are of such a length as to secure the trench walls over the entire work area.
