Abstract: A system for fastening a rail to a substrate has an anchor in the substrate, a fastener having a shank secured in the anchor and a head above the substrate, an angle guide plate vertically traversed by the shank, an annular part between the head of the fastener and the guide plate, and a spring clip engaged between the head and the part and shiftable transversely of the rail and of the shank between a preinstallation position horizontally offset from and not engaging the rail and a final installation position bearing vertically downward on the rail. A seal ring engages in both the preinstallation position and the final installation position around the shank and compressed between the part, the angle plate, and the shank so as to prevent water from traveling down the shank into the anchor.

Abstract: The invention relates to a plastic screw plug (6) for attaching a rail to a sleeper, in particular concrete sleeper, having an essentially cylindrical plug body which has at the head end a stem region (7) which preferably adjoins a plug crown (8) toward the bottom, and in the continuation of which stem region (7) has an outer thread (9) with which it can be turned out of or into the sleeper, and is provided with an inner thread (10) underneath the stem region (7) in order to receive a sleeper screw. The intention is to improve such a plastic screw plug, in particular, with regard to its operating properties such as uniform application of force into the sleeper, simpler mounting and replaceability, reduction of the risk of fracturing, and additionally to permit it to be used in a variable way.
