摘要： Rail construction including laterally adjacent frog sections with guard rails outwardly spaced to each side thereof by interposed liners. The components are interconnected by a transverse tightened bolt with vertical misalignment precluded by either nesting projections on adjacent abutting faces of the components or by a rigid, preformed sleeve press-fit within the bore receiving the bolt, the sleeve extending through the frog sections and at least partially through the liners.

摘要： 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.

摘要： A process for manufacture of a railroad track part, in particular a large points part, with rail parts such as a frog point and connecting rails, and the track part obtained. The track part is made of materials of differing composition, one of which is a carbon steel and one of which is an austenitic manganese steel, which are connected by welding and are subsequently subjected to a joint heat treatment. To permit joining of the materials without negative effects on their properties, the parts are joined directly by electron beam welding or indirectly via an intermediate layer comprising a nickel-based alloy, the joined parts then being heated to a temperature T and held over a time t such that for the austenitic manganese steel, solution annealing takes place, and for the carbon steel, austenitizing takes place. The railroad track part is partially quenched after the holding time t at temperature T, such that the austenitic manganese steel is provided in an sustenitic structure and the carbon steel is in a mixed structure with at least bainite and pearlite contents.
