  • Patent number: 8919661
    Abstract: A system for fastening a rail to a solid foundation, and a method for renovating a rail-fastening point. The system and the method allow a fastening point for a rail to be easily and economically renovated in such a way that a permanently reliable function of the renovated fastening is then ensured again while the worn support section remains. The system for fastening a rail to a solid ground foundation includes: a layer formed by a compensating mass applied to the support section; a base plate resting on the layer and extending over the support section, upon which the rail is supported in the finally installed state; a spring element for exerting a resilient elastic retention force on the rail; and a clamping element that can be anchored in the solid foundation for clamping the spring element.

  • Patent number: 8181887
    Abstract: A device for positional securing and guiding of rails for railway tracks for trains, in particular high-speed trains, includes guide plates. In general, rails are laid directly or indirectly by intermediate assembly of intermediate plates to fixed concrete track beds and guide plates, against which the rail base and possibly intermediate plates lie laterally. Guide plates are embedded on or in the concrete track beds, wherein the guide plates are fabricated of high-strength, form-stable material, preferably reinforced plastic, such as for example glass-fiber reinforced plastic, in particular polyamide. The device according to the invention allows to create guide plates which are overall more wear resistant. Wear resistance is achieved in that the guide plate within the surface area, on which the rail base rests, has an insert or areas provided with inserts, the insert being fabricated of slippable, low-abrasion or friction-resistant, low-wear or wear-resistant and flexibly resilient material.

More specifically, an anchor is provided that securely fastens to the track rail in a non-invasive manner for holding one or more signal lines to a surface of the track rail. In one embodiment, the non-invasive anchor utilizes a compressive force to clamp to a flange portion of the track rail. In this regard, first and second body members of the anchor may be advanced toward the toward opposing surfaces of track rail to compress the component between a portion of the anchor and a surface of the track rail. In one embodiment, a pawl prevents the withdrawal of these body members from one another such that the compressive force may be maintained once the anchor is applied to the track rail.

  • Publication number: 20100170955
    Abstract: This invention addresses issue of rail seat abrasion by completely removing all elastomers from directly contacting the rail by utilizing a shoulder post with a lower portion that is coated or encapsulated with a nonconductive material and a rolled or cast tie plate design that introduces a tie plate to the rail seat of the concrete tie. The coated or encapsulated lower portion of the shoulder is then cast into the concrete. By having the pad between the plate and the tie, it is subjected to vertical compression only with no rubbing action.

  • Patent number: 7717387
    Abstract: A rail clip for securing a strip heater to a rail that resists removal when subjected to intense vibration, such as when rail cars are passing overhead. The rail clip is configured with a U-shaped rail flange receiving area wherein the opposite sides of this receiving area are configured with at least one tooth each for securing the rail therebetween. For greater securement, multiple teeth on each side of this U-shaped receiving area would be employed and with at least one tooth on each side thereof being in alignment with the other. Furthermore, the teeth on at least one side of this receiving area would include multiple teeth, both pointed and elongated.

  • Patent number: 7673810
    Abstract: A rail fastening clip is used with a rail clip support having a rail clip slot of the kind used in K plates. The rail clip is formed from a U shaped member made of metal plate having a base and two arms tapered from the base to their tips, with the arms being bent inwardly beyond the base in a large arc and the tips are bent back toward the base and oriented for contact with the foot of the rail. The base is adapted to fit in the K plate slot of the rail clip support. The base of the clip has a leading edge remote from the arms that contacts the upper interior surface of the support slot to form at least a line of contact with the upper interior surface of the slot. The line of contact is about 6 mm. The design overcomes the problem of rotation of the clip within the support slot and is a more cost effective clip than that currently used with K plates.

  • Publication number: 20090294546
    Abstract: A clip for securing a rail seal element to a rail includes a generally L-shaped first clip member having a clamping arm and an elongate connector arm extending from one end of the clamping arm and capable of passing under the rail; a second clip member removably slidable on the connector arm; and a locking mechanism capable of releasably locking the second clip member against sliding movement along the connector arm. In use, the second clip member is removed from the connector arm so that the connector arm can be passed under the rail with minimum disruption of the ballast. The second clip member is then slid back onto the connector arm, and the assembled clip then oriented so that the rail and the rail seal are positioned between the clamping arm and the second clip member. The second clip member is then slid on the connector arm toward the clamping arm so as to tightly press the rail and rail seal therebetween.

  • Publication number: 20090090790
    Abstract: In a railroad system a track is formed of ties positioned at predetermined intervals along the right of way, and supporting a pair of rails. Shoulders are disposed in pairs adjacent to the sides of each rail and are partially imbedded in the ties to limit the lateral movement of the rails and define the track gauge. Between each pair of shoulders there is provided a pad disposed under the respective rail. Insulators are provided between the sides of the pad and a respective shoulder. Over time, friction between the insulators and the shoulders may cause excessive wear. This wear is compensated by one or more shims attached to the shoulders by a strong adhesive.

  • Publication number: 20080257973
    Abstract: The present disclosure relates to a system and method for non-invasively attaching components to railroad track rails. More specifically, an anchor is provided that securely fastens to the track rail in a non-invasive manner for holding one or more signal lines to a surface of the track rail. In one embodiment, the non-invasive anchor utilizes a compressive force to clamp to a flange portion of the track rail. In this regard, first and second body members of the anchor may be advanced toward the toward opposing surfaces of track rail to compress the component between a portion of the anchor and a surface of the track rail. In one embodiment, a pawl prevents the withdrawal of these body members from one another such that the compressive force may be maintained once the anchor is applied to the track rail.
