A rail clamp comprising two clamp elements (30a, 30b) securable together in clamping arrangement about a railway rail, wherein at least one of the clamp elements (30a, 30b) can include sensor retaining means to hold a sensor to make measurements relating to the rail. A first of said two clamp elements (30b) has a clamp head to engage a fish plate (14b) or a web-side of a railway rail. A clamp foot (34b) engages the underside of a railway rail foot (13). A second of said two clamp elements (30a) having a clamp head to engage the opposite fish plate or web-side of a railway rail and a clamp foot (34a) to engage the underside of the clamp foot (34b) of the first clamp element (34b). The first and second clamp elements (30a, 30b) are secured together by a connector (35), optionally a bolt, to a railway rail.

A track rail fastening system includes a direct fixation fastener assembly having a direct fixation fastener, and a laterally elongated support block. Fastener holes for receiving fastener-clamping fasteners, and fastener holes for receiving bracket-clamping fasteners, are formed in the support block. The respective sets of fastener holes are arranged in different anchor patterns. Fastener-clamping fasteners are received in one of the sets of fastener holes and claim direct fixation fastener to the support block. Bracket-clamping fasteners clamp a third-rail support bracket to the support block, and are received in one of the sets of fastener holes. The third-rail support bracket is cantilevered to the support block.

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.

A pre-buried casing tube uses glass fiber reinforced resin as the raw material to enhance the operation strength of the pre-buried casing tube, extend the service life of the pre-buried casing tube, and reduce maintenance cost of the railway transport system. The pre-buried casing tube includes at least one casing tube body, each casing tube body including at least one retaining element, the retaining elements provided in intervals along one side of the casing tube, each casing tube body disposed adjacently so as to form a passage for a screw, each retaining element provided in the passage for the screw.

A bonded fastener for a railway rail comprising: top and bottom generally horizontal plates bonded and separated by an insulating material wherein the top plate defines a rail bed; a plurality of clip housings wherein each clip housing houses part of a hold-down clip for attaching the rail to the bonded fastener; a plurality of anchor assembly areas wherein each anchor assembly area defines an opening through the bonded fastener for receiving an attachment device for attaching the fastener to a supporting surface; and one or more generally vertical barriers comprising part of the bonded fastener. Further, a first generally horizontal barrier may extend from the bonded fastener underneath each of the clip housings, and a second generally horizontal barrier may extend from the rail bed underneath the rail on each side of the bonded fastener.
