  • Patent number: 5158414
    Abstract: A rail attachment device which allows for longitudinal displacement of a rail. The rail attachment device includes a first element fixedly supported to a ribbed plate and having a vertical arm extending essentially parallel to the longitudinal direction of the rail. The rail attachment device also includes a second element which is connected to the web of the stock rail. Connecting elements connect the first element to the second element so as to allow for longitudinal shifting of the stock rail and second element with respect to the first element fixed to the ribbed plate. In one embodiment, the second element includes a web-plate fixed to the web of the stock rail by a bolt and a plate-like element connected to the web-plate and having longitudinally extending slots. The connecting elements pass through holes formed in the vertical arm and through the elongated slots.

  • Patent number: 4925135
    Abstract: An arrangement is proposed for controlled guidance of a wheel axle (22) or of a bogie of a rail vehicle passing over points, whereby the wheel contact point (48, 50) is subjected to a controlled influence such that the wheel axle runs substantially vertical to the track longitudinal axis. The controlled influence of the wheel contact point can be exerted by, for example, the stock rail (32) veering away outwards in the area that the blade begins.
