Mechanism and system for fastening track rail to a substrate and track rail fastening method
A fastening mechanism for coupling track rail to a substrate includes a fastener body formed by a metallic base and an overmolded non-metallic coating. Metallic pillars are coupled with the fastener body, and define bores for receiving anchors held fast within a substrate. The coating encases the metallic base and extends peripherally around the metallic pillars to position vibration-attenuating non-metallic material between the metallic base and the metallic pillars.
Plate element for a fastening point at which a rail, which is provided for rail vehicles, is fastened and fastening point
A plate element for a fastening point, at which a rail for rail vehicles is fastened to a fixed base. The plate element has an opening leading from the upper side thereof associated with the rail to be fastened to the underside thereof associated with the base, through which a fastening element for fastening the plate element onto the base is guided during use, which engages with an anchor fitting countersunk into the base, and a fastening point at which a rail for a rail vehicle is fastened to a fixed base. The plate element enables the fastening of a rail onto a fixed base, ensuring optimum electrical insulation. This is achieved by a ring element made from a flexibly resilient material sitting in the region of the mouth of the opening associated with the base.

Rail fastening arrangement and shim for such a rail fastening arrangement
A rail fastening arrangement in which a rail for a rail vehicle is fastened to a base, and to a shim. The rail fastening arrangement includes two guide plates, of which one guide plate respectively is associated with one of the longitudinal sides of the rail, and a shim which is arranged between the base and the rail. The shim, at its top, has a contact area on which the rail is supported, and, at its bottom, has a supporting surface by way of which the shim is supported on the base. The contact area and the supporting surface of the shim, viewed in a section located transversely to the longitudinal extension of the rail, enclose an acute angle. The edge at which the shim is thinner is arranged beneath the rail, fastening of rails oriented at a cant relative to the vertical in the region of points.

Fastening point, in which a rail forming part of a track for rail vehicles is mounted on a foundation
A fastening point for a rail on a foundation including a bedplate arranged on a support surface of the foundation. The bedplate includes a bearing surface formed on its underside associated with the foundation and also a through-opening, a spring element for exerting an elastic holding-down force on a rail foot and a clamping screw, which braces the spring element against the bedplate. The clamping screw is guided with its threaded shaft through the through-opening of the bedplate. The clamping screw acts with its screw head against the spring element and is screwed into a thread provided in a region of the through-opening of the bedplate. A free space is provided in a region underneath the bedplate in the extension of the through-opening of the bedplate, into which the threaded shaft of the clamping screw can be inserted.

Hot Forged Tie Plate for Railroad
A railroad tie plate has a generally prismatic body including a field side flange and a gauge side flange connected by an intermediate portion. The intermediate portion includes a rail seat for positioning a railroad rail. At least one of the flanges includes a protrusion extending in a thickness dimension of the tie plate. A hole extends into the at least one protrusion so as to receive a retaining device, such as an e-clip. The tie plate is made by hot forging, having a microstructure comprising pearlite and alpha-ferrite. The net shape of the tie plate may be achieved by forging without subsequent material addition and without subsequent material removal.
