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. The connecting elements are preferably pretensioned so as to have the plate-like element shift with respect to the vertical arm upon reaching a predetermined longitudinal force. A step arrangement between the plate-like element and vertical arm also prevents vertical shifting between the two.
