A portable railroad spike remover comprises a claw assembly extractor that is shaped to engage and secure a railroad spike previously installed into a rail tie. The claw assembly extractor may include a pair of jaw members that are pivotally connected to each other by a pivoting pin and a rotating pin. Each jaw member may include a lower end configured to contact and secure a railroad spike and a pair of upper members interlocked with each other and pivotally connected to the clevis fastener with the rotating pin. When the drive shaft is rotated, the claw assembly extractor and the mounting flange may move inside the main housing in a vertical direction to extract the railroad spike from the rail tie.

A portable railroad spike remover comprises an extractor that is shaped to engage and secure a railroad spike previously installed into a rail tie. A drive shaft is connected to the extractor such that as the drive shaft is rotated, the extractor is vertically raised and lowered within a main column. The extractor may have an opening extending through at least one side to engage the railroad spike.

A wire installation apparatus is provided. The wire installation apparatus includes a body through which a peg passes, a reel installed in the body to surround a wire, a wire guide member guiding the wire, and an external force transfer member transferring an external force, applied from the outside, to the peg so that the peg is driven into a ground. The wire is installed by the peg driven into the ground.

A railroad tie maintenance machine is configured to detect and seal spike holes in a railroad tie formed by the removal of railroad spikes. The vehicle includes a mothership vehicle and a shuttle cart that are connected by a tether. The shuttle cart is movable relative to the mothership vehicle. The shuttle cart includes a filler workhead having an imaging device, a light source, and an injection wand assembly. The imaging device is configured to take photographs or video beneath the shuttle cart while it travels along the railway. Using a computer vision system, the location of the ties and the spike holes in the ties are identified, after which the injection wand assembly is moved in lateral and longitudinal direction to overlie a spike hole. Thereafter, the injector can be inserted into the spike hole, after which a chemical solution is used to fill the spike holes.
