    摘要： A composition, device, and method for maintenance of railroad wood ties is presented herein. The device comprises a system for simultaneously filling rail spike holes in wood cross ties including a controlled system able to move in the x, y, and z planes. The system includes a product distribution box with multiple valves and dispensing lines for applying an environmentally friendly wood filler composition into multiple rail spike holes simultaneously. The wood filler composition is applicable for filling holes or gaps in wood to stabilize wood structures.

    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 comprise 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.
