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.

Systems, methods, and machine-readable media to facilitate installation and adjustment of railway components are disclosed. Aligning of a railway anchor manipulator and a railway fastener installer with respect to a railway tie may be caused. The railway anchor manipulator may be slidably coupled with a frame assembly of a railway workhead, and may include anchor tools. The railway fastener installer may be slidably coupled with the main shaft structure, may include a hammer assembly, and may be operable to install railway fasteners through holes of a railway tie plate. The railway fastener installer may be caused to install the railway fasteners. The railway anchor manipulator may be lowered to a deployed position, and railway anchors may be adjusted with the anchor tools.

A nail punching machine for driving in or pulling out rail spikes includes a driving mechanism, which is driven by an electric drive motor. The electric drive motor is supplied with electric power by an accumulator. The nail punching machine is held by an operator by at least one handle.

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 spike puller apparatus comprises a subframe, a pair of opposed puller arms for engaging with spikes to be pulled via a replaceable puller tool mounted on the end of each puller arm, a pair of horizontal shafts and an actuator to selectively translate each puller arm with respect to one another, an actuator to articulate each respective puller arm for pulling spikes, an A-frame connected to the subframe to resist and/or apply pulling forces to a spike being pulled, and a vertical actuator connected to the A-frame to cause the vertical slide carrier to move up and down along the pair of vertical shafts to effect a spike pulling operation. The respective puller arms are independently controllable, and may be selectively staggered with respect to one another along a rail to allow selective independent and/or simultaneous pulling of rail spikes and/or anchor spikes on opposite sides of the rail.
