Abstract: A system and a method for fastening a rail to a substrate, with a guide plate for laterally guiding the rail that has a standing surface associated with the substrate, a support element to support the guide plate in the assembly position, a spring element supported on the guide plate and at least one spring arm for exerting a resilient holding force onto the foot of the rail, and a tensioning means for tensioning the spring element. The fastening can be assembled in that the support element has a support lug supported on the substrate in the assembly position to reach under the standing surface of the guide plate in a way that the guide plate is supported on the substrate via the support lug in the region where the guide plate and support lug overlap.

Abstract: A screw anchor for concrete attachment in a railway sleeper and to a force-fit connection using a rail screw containing a threaded section with external threads disposed on an exterior of the screw anchor and internal threads disposed in the screw anchor; and an upper partial section without external threads which is disposed in a mounted state close to an anchor opening. The screw anchor utilizes material with high elasticity arranged in the upper partial section, wherein this material, when in a mounted state, forms an elevation which extends in an upward direction over an upper side of an end surface of the upper partial section and reduces a free opening section of the inner chamber of the upper partial section.

Abstract: A profiled element for damping sound vibrations on rail lines including a first main surface, which is designed and dimensioned such that it can be attached as a support surface to sections of the rail web without having to provide an adhesive layer, wherein the profiled element further has at least one recess on a front surface located opposite of the support surface, wherein the at least one recess in the front surface is designed for the positive engagement of an elastic fixing element for fixing the profiled element against the rail web, and at least one widened region of the profiled element in the region of the front surface, said widened region present in the lower region of the front surface in an installed position.

Abstract: The invention relates to a screw anchor for the concrete attachment in a railway sleeper and to the force-fit connection by means of a rail screw, comprising a threaded section (14) with external threads (18) disposed on the exterior of the screw anchor (10) and internal threads (19) disposed in the screw anchor; and an upper partial section (16) without external threads which is disposed in the mounted state close to the anchor opening (26). Said invention is characterized in that material with high elasticity is arranged in the upper partial section (16), said material, when in the mounted state, forms an elevation which extends in the upward direction over the upper side of the end surface (36) of the upper partial section (16) and reduces the free opening section of the inner chamber of the upper partial section (16).

Abstract: A device for positional securing and guiding of rails for railway tracks for trains, in particular high-speed trains, includes guide plates. In general, rails are laid directly or indirectly by intermediate assembly of intermediate plates to fixed concrete track beds and guide plates, against which the rail base and possibly intermediate plates lie laterally. Guide plates are embedded on or in the concrete track beds, wherein the guide plates are fabricated of high-strength, form-stable material, preferably reinforced plastic, such as for example glass-fiber reinforced plastic, in particular polyamide. The device according to the invention allows to create guide plates which are overall more wear resistant. Wear resistance is achieved in that the guide plate within the surface area, on which the rail base rests, has an insert or areas provided with inserts, the insert being fabricated of slippable, low-abrasion or friction-resistant, low-wear or wear-resistant and flexibly resilient material.
