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.

A track-mounting assembly secures a longitudinally extending rail direction to a substrate and has a frame fixed to the substrate and a track plate fitted in the frame. A vertically throughgoing aperture of the frame has an inner edge formed by a longitudinally extending gauge surface directed transversely toward a field side of the assembly and a transversely oppositely directed and longitudinally extending field surface. The track plate carries the rail and has an outer edge is itself formed by a longitudinally extending field surface spacedly transversely confronting the gauge surface of the aperture and a longitudinally extending gauge surface spacedly transversely confronting the field surface of the aperture. The field surface of the track plate is of substantially greater area than the gauge surface of the aperture. An elastomeric mass fills between the frame and the track plate.

A boltless brace assembly for a rail includes a base block interlocked with a brace, and further includes a wedge to be inserted between an upper surface of the base block and a lower surface of the brace, thereby applying an upward force to the brace and a resultant downward force to secure the rail base. The brace assembly may be modified to provide a universal brace assembly, a resilient brace assembly, or a frog base clamp.

A system for a screwless rail fastening includes a spring element and a supporting collar. The spring element has a bearing section, a curved section, a holding-down section, aligned in the opposite direction to the bearing section, a curved section curved in the direction of the bearing section, and a locking section aligned transversally to the bearing section. The supporting collar includes a fastening section for retaining the supporting collar on the foundation, a carrier section supported by the fastening section, a bearing recess formed on the carrier section for mounting of the bearing section, and a locking head supported by the carrier section on which a counter-bearing for the locking section is formed so that the locking section is retained in a position relative to the bearing section of the spring element.

A mechanism for coupling a track rail to a substrate includes a rail plate and a base plate, where the rail plate surrounds the base plate. An overmolded coating is formed of a non-metallic material and encases the rail plate and the base plate. Related methodology is disclosed.

A vehicle rail mounting device (10) Is provided for mounting a vehicle rail (12) on a support structure (14). The device Includes a bottom piece (16), an elastomeric bearing element (18) to be supported on the bottom piece, top cover elements (22) having elastomeric element retainers (54), a top piece (20), and rail connectors (82). The elastomeric element retainers are provided to retain the elastomeric element in place while the elastomeric element is adapted to retain the top piece, and hence the rail connectors, and therefore also the rail, in place. The top cover elements can be connected to the to the bottom and to the support structure to keep the whole device in place.
