Abstract: A spiker anvil is provided for use in a rail fastener driving workhead unit. Included in the present spiker anvil is a head with an outer periphery, the head outer periphery including an indentation that mates with a hammer pin of the rail fastener driving workhead unit. Also included in the spiker anvil is a body defining a body outer periphery and a tip defining a tip outer periphery, a substantially flat bottom surface, a first chamfer and a second chamfer, the bottom surface being perpendicular to the tip outer periphery, and the first and second chamfer connecting the bottom surface and the tip outer periphery. Further, the spiker anvil includes a cavity within the tip with an opening in the bottom surface and an insert placed within the cavity, such that the insert includes an end which extends beyond the bottom surface.

Abstract: A tamper tool is provided for use in adjusting railroad ballast and constructed and arranged for use with a tamper tool holder attached to a railroad tamping machine. Included on the tool is a shaft with a first portion, a second portion, and a central portion disposed between the first and second portions, and a front surface, a rear surface, and two side surfaces. The first portion has through bores extending from the front surface to the rear surface, and the central portion has a first cross-section at an upper end, a second cross-section at a lower end. An area of the first cross-section is greater than an area of the second cross-section, and the shaft tapers between the first cross-section and the second cross-section. A paddle for tamping is attached at a free end of the second portion.

Abstract: A fastener driving workhead unit is provided for performing an operation on spikes of a railroad track having a plurality of ties, and includes a hammer housing configured for accommodating a hammer, the housing being attached to a hammer bushing having a hammer bushing clamp. Also included in the workhead unit is an anvil assembly having an anvil and an extension coupler, the extension coupler being releasably secured to the hammer bushing by fastening the hammer bushing clamp. Further, the workhead unit includes a jaw assembly having a jaw block, the jaw block having at least one jaw block clamp for releasably securing a guide rod to the jaw block by the jaw block clamp, such that the anvil freely reciprocates in the hammer housing for driving the spikes into the plurality of ties.
