A one or two-part top concrete layer, and rail fasteners are formed in before the concrete has hardened. The rails are temporarily located beside the space for the concrete layer, which is fabricated by a sliding finisher rolling on the rails (3). The positioner device for the rail fastener elements also moves on the rails. The rails are positioned on the track bed, and fixed by side and height-adjustable auxiliary rail bearings (4), with dowels (5), which are aligned with the rails. The finisher consists of a trough driven by a cable winch, with molding parts at the back to mold the concrete layer. This consists of neighboring longitudinal continuous longitudinal beams (1), which are connected to each other by anchors in transverse bores. |
