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.

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.

A direct fixation track rail fastener includes a rail plate having a first restraint hole and a second restraint hole upon opposite lateral sides of a rail support surface. The fastener also includes a frame including a first vertical protrusion and a second vertical protrusion received through the first restraint hole and the second restraint hole. A non-metallic cushion extends between the rail plate and the frame and vertically upward to surround the first vertical protrusion and the second vertical protrusion within the first restraint hole and the second restraint hole, respectively. The configuration assists in limiting displacement of the rail plate and frame relative to one another.

A direct fixation track rail fastener includes a first clip shoulder and a second clip shoulder each having a clip tunnel formed therein. Each clip tunnel is formed in part by a plurality of clip contact faces defining a first prong contact line and a second prong contact line for a prong of a rail clip. The configuration of multiple line contacts prevents undesired displacement of a rail clip during service.

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.

A system for a screwless rail fastening includes a spring element and a supporting collar. The spring element has a bearing section, a curved section, a holding-down section, aligned in the opposite direction to the bearing section, a curved section curved in the direction of the bearing section, and a locking section aligned transversally to the bearing section. The supporting collar includes a fastening section for retaining the supporting collar on the foundation, a carrier section supported by the fastening section, a bearing recess formed on the carrier section for mounting of the bearing section, and a locking head supported by the carrier section on which a counter-bearing for the locking section is formed so that the locking section is retained in a position relative to the bearing section of the spring element.

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 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.

The invention relates to a tension clamp for holding down a rail for rail vehicles. It includes a middle section with two legs, two torsion sections connected to the legs leading laterally outwards and having a support zone on their underside, by which the tension clamp is supported during use, and two supporting arms connected to the torsion sections. The supporting arms extend to the front side of the tension clamp and have a spring section and a support section, which has a support zone by which they are supported during use. The support sections of the supporting arms point laterally outwards so that the straight lines intersect in a region located on the rear side of the tension clamp. The invention also relates to a guide plate that protects a tension clamp against breakage during excitation in the range of its natural frequency, and a rail fastening point.

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.
