Abstract
A railway rail fastening clip, for fastening a railway rail to an underlying rail foundation, 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 portion of the plate to form a 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 extending from the opposite side of the central region of the plate to form a toe portion of the clip for bearing on the railway rail. The toe portion of the clip is provided with an insulator retainer for retaining thereon a toe insulator for electrically insulating the clip from the rail.
