An elongated rail fastener apparatus for use near an obstacle such as a guard rail, or other location where space is restricted. The fastener preferably extends past the obstacle and is provided with a shoulder having at least one elevated notch, positioned to allow installation of the clip with a vertical and lateral movement, and without the application of a large force perpendicular to the rail. A U-shaped embodiment of the fastener is also described.

Track guards for use with overhead doors at loading docks, residential locations, and other facilities are described herein. In some embodiments, the track guards described herein can be two-part assemblies having a first part (e.g., a base member) that mounts directly to a door jamb, and a second part (e.g., an outer member or cap) that can be adjustably positioned relative to a door guide rail and then fixedly attached to the base member. In some embodiments, the outer member can include recesses or pockets, elongate edge features, and/or other shapes that are configured to clip onto or otherwise cover a portion of the guide rail to provide support and/or prevent, or at least reduce the likelihood of, damage from operational loads and/or impacts to the guide rail. Additionally, in some embodiments the track guards described herein can include various types of attachment features so that lights, reflective elements, motion sensors, fans, and/or other devices can be quickly and easily mounted to the track guard at various positions near the door opening to facilitate operations at the loading dock.

A guardrail system for use along a roadway. The system can include a longitudinal body having one or more longitudinal void spaces formed therein, at least one substantially vertical post connected at one or both ends of the body, and a longitudinal member disposed within any one of the longitudinal void spaces of the body having a crosswise ultimate tensile strength that is at least 20% greater than the crosswise ultimate tensile strength of the longitudinal body.

A profile for the composition of a railroad rail with the provision for at least one pair of webs in each profile of the rail, in addition to being provided with a set of cutouts of a plurality of geometric shapes that allow the crossing of wires and cables for several purposes. The webs arranged more laterally to the center of the rail provide greater stability to the rail the plurality of holes enables greater capacity to absorb stresses and vibrations, consequently, greater stability for the train, especially at high speeds. The adopted geometries also present a greater mechanical strength in relation to common rail profiles compared to the same amount of used material.

The invention may be described as including a switch guard casting, a switch guard assembly for a railway intersection, as well as a rail intersection design and a switch guard assembly therefor.
