Claim Text:
1. An apparatus comprising: a railway rail fastening clip for fastening a railway rail to an underlying rail foundation; and a rail clip insulator for electrically insulating the clip from a railway rail, wherein the railway rail fastening clip is formed of an elongate plate shaped such that a central region of the plate has in profile the form of a letter C, a first end region of the plate extending from one side of the central region of the plate to form a substantially planar base portion of the clip for engaging a rail fastening anchoring device secured to the rail foundation and a second end region of the plate having a free end and extending from the opposite side of the central region of the plate to form a toe portion of the clip for bearing on a foot of the railway rail, such that in profile the second end region extends further than the first end region, wherein the toe portion of the clip is provided with a throughhole which is not open at the free end of the second end region and is arranged such that, when the clip is in its operative configuration, part or all of the throughhole lies above the foot of the rail, the throughhole being configured to receive a corresponding portion of the rail clip insulator, whereby the insulator can be retained on the toe portion of the clip, wherein the rail clip insulator comprises: wherein the said insulator is arranged on a lower, load bearing surface of the toe portion of the said clip such that the spigot of the insulator extends through the said throughhole of the said toe portion.
