    摘要： Apparatus, devices, assemblies, systems and methods of using w spring clips over spikes for holding railroad tie spikes down to wood and concrete railroad ties and hold the spike heads to the rails. A first embodiment can use rail tie plates with box holders for holding end portions of a w shaped spring steel clip to press against cap heads of railroad tie spikes. A second embodiment can use a rail tie plates with vertical supports for horizontal bars over heads of railroad tie spikes. A third embodiment can use rail tie plates with vertical studs and upper threaded ends with flat plates attached by nuts over heads of rail road tie spikes, and with cotter pins locking the nuts in place. Additional embodiments include metal structures fastened, welded and/or forged to tie plates for allowing w shaped spring clips with mid portions that hold down heads on spikes to prevent the spikes from coming out.

    摘要： A method for maintenance of railroad wood ties is presented herein. The wood filler composition used in the method is applicable for filling holes or gaps in wood to stabilize wood structures. The composition comprises at least unintahite, also known as asphaltum or Gilsonite, and sand. The composition may further comprise a water repellant and a wood preservative. The composition is non-carcinogenic. The method comprises filling a hole with the dry composition described herein. The wood member may be a railroad tie and using an appropriate filling device, at least two holes, or at least four holes may be filled at one time.

    摘要： A railway spike for connecting an associated metal member with an associated wood member includes a head including an annular flange and a standoff extending axially from the flange. An intermediate section extends axially from the standoff. At least one holding ring is disposed on the intermediate section. The at least one holding ring extends radially away from the intermediate section and is adapted to engage the associated wood member. A shank extends axially from the standoff. The shank includes a thread which is adapted to engage the associated wood member.

    摘要： Embodiments of the present invention are directed to improved designs of railroad spikes and improved methods of manufacturing the same. According to one exemplary embodiment, a method for manufacturing a railroad spike may have the steps of: preparing a metal blank having a substantially circular cross-section; subjecting the metal blank to at least one cold heading process and at least one cold extrusion process to form a railroad spike having (a) a circular head with a fillet at its bottom side that is angled to engage a railroad tie plate or rail base and (b) a non-threaded shank with a substantially square cross-section and a chiseled tip; and coating the railroad spike with an anti-corrosion material.
