A track-mounting assembly secures a longitudinally extending rail direction to a substrate and has a frame fixed to the substrate and a track plate fitted in the frame. A vertically throughgoing aperture of the frame has an inner edge formed by a longitudinally extending gauge surface directed transversely toward a field side of the assembly and a transversely oppositely directed and longitudinally extending field surface. The track plate carries the rail and has an outer edge is itself formed by a longitudinally extending field surface spacedly transversely confronting the gauge surface of the aperture and a longitudinally extending gauge surface spacedly transversely confronting the field surface of the aperture. The field surface of the track plate is of substantially greater area than the gauge surface of the aperture. An elastomeric mass fills between the frame and the track plate.

Typically, a tie plate assembly for supporting a rail on a tie includes a tie plate and a spike that is driven through the plate into the tie to secure the tie plate to the point. A sleeve is provided on the plate that is inserted into a tie to prevent the deflection of the spike with respect to the ties wheels of a train pass over the tie.

A low maintenance rail seat has recess in the concrete tie and an abrasion plate that covers the floor of the recess and its sides parallel to the rail base. The abrasion plate includes ribs which seat in additional recesses in the tie to retard longitudinal movement. The anti-abrasion assembly preferably has four flanges which wrap around the top of concrete tie to prevent dust particles from entering and abrading the concrete rail seat. These flanges also wrap around the support shoulder for additional resistance to longitudinal movement. The components are designed to provide 8.5 of lateral support along the side of the rail base while the traditional e clip fastener provides only 3 of lateral support. The interlock feature between the anti-abrasion assembly and the concrete tie also minimizes relative movement between abrasion plate and concrete tie, which results in less concrete surface abrasion.

A modular fastening for track crossings includes a lower plate, an upper plate and an outer shoulder at each end of the plates, attached by means of adhesive bonding, which include means for anchoring the fastening on a surface. The upper plate includes a smooth central segment located between two grooved areas in correspondence with the ends of the upper plate. The present invention also includes two inner shoulders with lower grooves which can engage and fit into the grooved areas of the upper plate, where said inner shoulders include means for housing and securing an elastic fastening clip for fastening a railway rail.

A fastening mechanism for coupling track rail to a substrate includes a fastener body formed by a metallic base and an overmolded non-metallic coating. Metallic pillars are coupled with the fastener body, and define bores for receiving anchors held fast within a substrate. The coating encases the metallic base and extends peripherally around the metallic pillars to position vibration-attenuating non-metallic material between the metallic base and the metallic pillars.

A railroad tie maintenance machine is provided that installs or removes rail clips relative to a plurality of anchor sockets and rails. The machine includes a chassis and a workhead mounted thereto, with a tool configured to either install or remove the rail clips mounted to the workhead. The installation tool includes a curved upper wall configured to engage with the upper side of a rail clip, as well as a side wall configured to engage with a side of the rail clip, such that longitudinal movement of the rail clip is achieved even if the rail clip does not conform to standard sizes or shapes. Various tools can be selected and installed relative to the workhead depending on a number of characteristics associated with the project, including the type of clip, the type of anchor, the type of tie, and any other relevant factors.

The invention relates to a measuring arrangement for monitoring a railway track having rails fastened to sleepers, wherein a fibre optic cable is connected to a measuring device in order to detect a strain acting on a rail. In this, the fibre optic cable is clamped in a detachable manner into at least one rail fastening. In this way, a strain transmitted from the rail via the rail fastening to the sleeper acts directly on the fibre optic cable.
