An improved rail anchoring spike that includes barbs is used for fastening metal to ties. The spike includes a head having one or more flanges and a stand-off extending axially from the flange(s). The spike includes a shank extending axially from the stand-off to form a tapered tip. The shank is adapted to engage dense material of the tie by a combination of threads and barbs on the shank. The threads are generally parallel and extend over a threaded portion of the shank. The shank includes a plurality of barbs positioned in a lower half of the threaded portion. Each barb is positioned between a pair of threads. Each barb is configured to minimize damage to fibers of the tie during installation of the spike as the fibers relax behind, and engage with, a barbed end. This prevents movement of the spike over time despite deterioration of the tie.
An improved rail anchoring spike that includes a conical swell adapted to engage with a hole in a metal tie plate during fastening of the metal tie plate to a tie. The conical swell has a smaller diameter toward a pointed end of the spike and a larger diameter toward a head of the spike. The smaller diameter is slightly larger than a diameter of a body of the spike. An angle formed by the conical swell relative to a center line passing through a center of the body of the spike matches an angle of the hole in the metal tie plate relative to a center of the hole.

Methods, system and apparatus are disclosed, including a tie fastener apparatus for attaching railroad ties to a superstructure. The apparatus comprises a threaded hook bolt, including a hook to engage the underside of a flange of a beam. The apparatus further comprises a cross strap configured to engage with a flange of the beam. The apparatus further comprises a metal member for engaging plural ties. The metal member includes a tie fastener hole at plural locations. A nut fastens a threaded end of the threaded hook bolt for installation when the threaded hook bolt is passed through the bolt hole. When the threaded hook bolt is installed, the hook engages the superstructure, and a neck of the threaded hook bolt engages the cross strap. The apparatus is installed from above the superstructure without drilling holes in ties or the superstructure, or requiring manned installation from below the superstructure.
Methods, systems, and apparatus, including an apparatus that is a rail anchor comprising a head, a tail, and a belly section. The belly section comprises a top surface, a bottom surface, and two side surfaces. Each side surface comprises a contact-bearing surface area. The head comprises a bend along a length of the head. The tail comprises a notch. Each contact-bearing surface area has a surface area of at least 3 square inches and is adapted to extend at least 1.5 inches downward from the top of a railroad track crosstie along a side of the railroad track crosstie.
