Railway fastener for use with crossties
A fastening system configured to attach railroad crossties to one or more support structures such as the girder of a bridge. The fastening system includes a plate mounted on a crosstie and a clip attached to the plate that is configured to provide a force between the support structure and the crosstie and secure the crosstie in place.
Method for laying a rail of a railway track
A work train lays a rail of a railway track. The work train has a heating device with a heating zone, gas burners, and a radiant body interposed between the gas burners and the heating zone. The radiant body has openings that open into the heating zone. The work train is moved in a laying direction, so that at each moment a portion of the rail to be fixed passes through the heating zone. Heat is supplied to the rail to be fixed through the heating zone by feeding the gas burner so that no flame emerges from the openings in the heating zone and that at least 75% of the heat supplied to the rail is transmitted by radiation from the radiant body. Then the rail is fixed after the heat has been applied to a tie of the railway track behind the heating zone in the laying direction.
CONCRETE CROSSTIE
A monoblock concrete crosstie for railway tracks that achieves a high performance in operation includes a steel structure that is formed from ultra-resistant high strength steel plates embedded in a concrete element and having pre-stressed cold rolled wires with ends that form button head knots which are anchored to the steel plates. The crosstie includes rail seats with a convex channeled formation that is mateable with an extending member of a faceplate wherein the railseat has a width less than the width of the faceplate, and a center of the face plate has a first distance from a center of the concrete element and a center of the rails seat has a second distance from the center of the concrete element, the first distance greater than the second distance.

Tie plate for railroad tracks with spike protectors
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.
RAIL MOUNTING DEVICE AND METHOD FOR FIXING RAILS TO REINFORCED CONCRETE RAILWAY SLEEPER
The object of the invention relates to a rail mounting device (10) for fixing railway rails (12) to reinforced concrete sleepers (14) which device (10) has a first rail (12) non-fixing state and a second rail (12) fixing state, and which device (10) contains an anchoring element (18) fixed to the reinforced concrete sleeper (14) provided with an open or closed bracket piece (16), and a rail-clamping plate (20) partially or entirely encompassed by the bracket piece (16) of the anchoring element (18), the essence of which is that the rail-clamping plate (20) is a flexible flat plate, and the anchoring element (18) of the rail mounting device (10) has an upper surface which is formed substantially flat and which is at an angle to the upper plane (22) of the reinforced concrete sleeper (14) such that the distance between the first edge of the upper surface of the anchoring element (18) closer to the rail (12) and the upper plane (22) of the reinforced concrete sleeper (14) is smaller than the distance between the second edge of the upper surface of the anchoring element (18) more distant from the rail (12) and the upper plane (22) of the reinforced concrete sleeper (14), and in the first state of the rail mounting device (10) the rail-clamping plate (20) lies on the upper surface of the anchoring element (18), whereby the rail-clamping plate (20) is also arranged at an angle to the upper plane (22) of the reinforced concrete sleeper (14) and in the first state of the rail mounting device (10), the angle between the rail-clamping plate (20) and the upper plane (22) of the reinforced concrete sleeper (14) is between 5 to 20 degrees and the rail-clamping plate (20) is made from a maximum of 6 mm thick cut sheet steel.
The object of the invention also relates to a method for fixing railway rails (12) to reinforced concrete sleepers (14).
Boltless rail brace
A boltless brace assembly for a rail includes a base block interlocked with a brace, and further includes a wedge to be inserted between an upper surface of the base block and a lower surface of the brace, thereby applying an upward force to the brace and a resultant downward force to secure the rail base. The brace assembly may be modified to provide a universal brace assembly, a resilient brace assembly, or a frog base clamp.
