摘要： An anchoring assembly for fastening a railway rail to an underlying foundation, the anchoring assembly including a base plate configured to receive the rail, a fastener configured to fasten the base plate to the underlying foundation, and a rigid sleeve defining a passage through which a stem of the fastener passes. The base plate comprises an opening and the sleeve is configured to extend through the base plate opening, the sleeve extends a distance greater than a thickness of the base plate such that the sleeve extends from a top surface of the base plate and beyond a bottom surface of the base plate when installed, and the sleeve is configured such that a compressive load applied by the fastener when installed is transmitted through the sleeve to the underlying foundation.

摘要： Methods of assessing wear of an electrical insulator and rail pad of an assembled rail fastening system utilize data from a 3D scan of the system to derive measurements of the system from which wear of the side post of the electrical insulator, or wear of the rail pad beneath the rail, may be assessed.

摘要： An anchoring device for use in retaining a railway rail fastening clip having first and second leg portions and a rail-bearing portion therebetween. The anchoring device includes a base member, an opening in the base member configured to receive a fastening component for fastening the anchoring device to an underlying foundation, and first and second clip-retaining sides extending from said base member with the first clip-retaining side being spaced apart from the second clip-retaining side so as to define a space therebetween for receiving the rail-bearing portion of the clip. Each clip-retaining side comprising upper and lower clip contact walls defining a passageway for receiving one of the leg portions, wherein the leg portions contact the clip contact walls of the respective clip-retaining sides as the clip moves from a wedged position towards an engaged position where the rail-bearing portion of the clip bears on the rail.

摘要： In a railroad system a track includes ties positioned at predetermined intervals and supporting a pair of rails. Shoulders are disposed in pairs adjacent to the sides of each rail and are partially imbedded in the ties to limit the lateral movement of the rails and define the track gauge. Over time, friction between the insulators and the shoulders may cause excessive wear and a gap therebetween. This wear is compensated by a shim attached to the shoulders.

摘要： A rail pad can have a major face forming a railseat portion on which a foot of a railway rail sits when the pad is in use, the railseat portion having opposite side edges to at least part of each of which a respective upstanding portion of the pad can be connected, wherein the pad does not have any part which extends laterally from the railseat portion in a same plane as the railseat portion. The respective upstanding portion can be connected to a projection of the rail pad which extends laterally from the respective upstanding portion such that the projection can be vertically spaced from, and does not overhang, the railseat portion, the projection spaced from ends of the respective upstanding portion such that the projection can be configured to interlock with a corresponding opening in a front part of one of the railway rail clip anchoring devices.

摘要： A plate assembly for securing a rail to a tie that includes a clip and a shoulder with an orifice. At least one of the clip and the shoulder are modified by changing their respective shape to form a positive interference fit therebetween. The modification is provided to ensure that the clip is maintained with its leg partially inserted into the shoulder orifice during staging.

摘要： An improved screwed fastening system for railway rails is proposed to allow rail fastening clips to be moved onto and off the rail more easily, facilitating track installation and maintenance. One improvement comprises providing in the screwed fastening system a clip guiding device, for guiding the rail fastening clip whilst it is being driven, which has an asymmetrically-located hole for receiving the screw-threaded shank of a screwbolt. Another improvement comprises providing in the screwed fastening system a rail fastening clip and screwbolt assembly which have inter-engaging driving portions. In each case, rotation of the screwbolt in one direction brings about translational movement of the rail bearing portion of the clip away from the screwbolt, and rotation of the screwbolt in the opposite direction brings about translational movement of the rail bearing portion of the clip towards the screwbolt.
