ABSTRACT ELECTRICALLY INSULATING RAILWAY RAILS FROM RAIL-FASTENING MEANS In order to electrically insulate a flange-footed railway rail from a clip that bears downwardly upon the upper surface of the rail flange and from an anchorage at one side of the rail flange there is provided an electrically insulating member with a first portion that is interposed between the rail clip and the upper surface of the rail flange. A second portion of the electrically insulating member is interposed between the edge of the rail flange and the anchorage. The electrically insulating member also includes a metallic reinforcing member having an elongate portion that has a flat lower surface and which is interposed between the rail clip and the first portion of the electrical- ly insulating member. Extending along and upwardly from the elongate portion is a reinforcing rib, while two spaced-apart projections extend sideways from the remainder of the reinforcing member. Part of the anchorage lies between these projections, so that the reinforcing member cannot move far along the rail, and there is no part below the aforementioned flat surface.
