The invention relates to a tension clamp for the holding of a rail for rail vehicles and a rail fastening point. The tension clamp has a central section having two legs, two torsional sections connected thereto and leading away laterally in an outwards direction having a supporting zone, and two supporting arms connected to the torsional sections. The supporting arms run to the front face of the tension clamp and have a spring section and a support section with a supporting zone. The fact that the support sections point laterally in an outwards direction such that the straight lines which in each case connect the centers of the supporting zones and the torsional section allocated to the supporting arm in an area on the rear face of the tension element increases the natural frequencies of the tension clamp such that they are outside of stimulation frequencies that occur in practice.

A railroad fastening system that includes a see-thru (transparent or translucent) rail seat assembly which allows for immediate visual feedback to assess whether that a sufficient amount of adhesive material has been applied to a crosstie during the installation of a rail seat assembly on a crosstie to ensure a long-lasting bond and a proper cant, flatness and height of a rail seat assembly.

A rail fastener comprises a rail support in a form of a bracket secured to a rail base and an lever oriented in perpendicular to the rail longitudinal axis, wherein one end of the lever is articulated to the bracket by a silentblock and the other end comprises a rail mounting platform equipped with limiters of the rail displacement in the direction perpendicular to the rail track axis. The rail is secured to the rail support by two clips disposed astride the rail. Some ends of the clips are taken under the lower surface of the rail platform, while the other ends abut on the upper surface of the rail flange via hexagonal adjusters each having an orifice located eccentrically in relation to the hexagon axis and receiving the other end of the clip. The rail fastener further comprises two elastic members disposed between the rail and the rail base astride the lever, and their thickness is selected so as to form a gap between the rail base and the lower surface of the lever in a position when the rail receives a load of a train wheels.

An assembly for securing a longitudinally extending rail for rail vehicles has a metallic base plate detachably fixed to a solid substrate. Rail holddowns secure the rail to the base plate, and retaining devices anchored in the substrate and pressing the base plate down against the base plate.

A fastening point for a rail on a foundation including a bedplate arranged on a support surface of the foundation. The bedplate includes a bearing surface formed on its underside associated with the foundation and also a through-opening, a spring element for exerting an elastic holding-down force on a rail foot and a clamping screw, which braces the spring element against the bedplate. The clamping screw is guided with its threaded shaft through the through-opening of the bedplate. The clamping screw acts with its screw head against the spring element and is screwed into a thread provided in a region of the through-opening of the bedplate. A free space is provided in a region underneath the bedplate in the extension of the through-opening of the bedplate, into which the threaded shaft of the clamping screw can be inserted.

A clip insertion system is disclosed inserting and/or removing clips from rail plates. The clip insertion system described herein may comprise a hand tool that positions and inserts a clip into a rail plate that is attached to the railroad tie. The clip secures the steel rail to the tie. This invention represents a significant improvement over existing clip setting hand tools by improving useability, reducing safety risks, and increasing efficiency in the process/method of securing the rail using clips and/or other clip-based technologies. This system also provides and improved method of moving and positioning the tool as it is moved to successive clip insertion locations.

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.

An elongated rail fastener apparatus for use near an obstacle such as a guard rail, or other location where space is restricted. The fastener preferably extends past the obstacle and is provided with a shoulder having at least one elevated notch, positioned to allow installation of the clip with a vertical and lateral movement, and without the application of a large force perpendicular to the rail. A U-shaped embodiment of the fastener is also described.

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.
