  • Patent number: 9683883
    Abstract: The present invention relates to a weighing module for measuring wheel contact forces of rail-bound vehicles, comprising a measuring rail and a number of strain gauges, wherein the strain gauges are applied directly on the measuring rail. The measuring rail comprises a load introduction region, made of at least one load introduction part, and at least two deformation bodies, which are connected fixedly in each case to a load output plate and, via a hinge, to the load introduction region. The strain gauges are arranged on the deformation bodies and capture the shear strain acting between the hinges and load output plates.

  • Patent number: 6672516
    Abstract: A miter rail system for spanning a railroad track joint includes a fixed rail and a lift rail formed from thick web rail stock. The joining ends of the fixed and lift rails are notched to interfit with each other along a predetermined longitudinal extent along the notches so that at least gage sides of the associated fixed and lift rails are in alignment with each other to provide a generally smooth and uninterrupted surface for rolling stock wheels. Preferentially, the inward facing edge of the notch is substantially entirely coextensive with a side of the thick web as a result of milling out, once the ends of the rails adapted to face each other have been bent.

  • Patent number: 6000624
    Abstract: A miter rail system for spanning a railroad track joint including a fixed rail, a lift rail and a rider rail connected to the fixed rail. The rider rail has an upper surface including a central portion defined by an arc of constant radius and opposite end portions. The apex of the central portion is greater in height than the height of the fixed rail and lift rail, and the height of the opposite end portions at opposed end faces of the rider rail is sufficiently low to avoid contact by a rolling stock wheel.

  • Patent number: 5709152
    Abstract: A device for joining two spaced confronting fixed ends of two adjacent rails which are misregistered in a vertical, a horizontal or a longitudinal direction without forming a step therebetween. In one form the joint device includes a universal joint rail 1C disposed between two spaced fixed ends 2A, 2B and joined with them via universal joints 5. In another form, the joint device includes an expansion joint rail 3A disposed longitudinally between the fixed ends via a longitudinally movable connecting bar 8 and a resilient member 10.
