Abstract: In a reversing device for rails which are swivelable around a swivelling axis, or for movable frogs within the crossing area of a railway switch, the swivelable rails or, respectively, the movable frogs are supported in their position being in alignment with wing rails or, respectively, connecting rails or, respectively, being in contact with such rails by supporting ro)$

Abstract: This invention relates to an improvement in a frog for switches, in particular for rapid transit switches, with a junction rail mounted in a rotatable manner and adapted to close a gap between pairs of rails of straight or branch track, the improvement comprising that the two ends of the junction rail have the shape of an isosceles triangle and the corresponding ends of a transit rail taper on one side, whereby a continuous rail-head profile is formed when the junction rail abuts the transit rail.

Abstract: A switching system for a transportation system of the type employing a guideway and vehicles adapted to travel along the guideway. A guideway junction is provided having a first end communicating with a first portion of the guideway and having a bifurcated, second end communicating with second and third, mutually diverging portions of the guideway. A movable guide rail is positioned adjacent the first end of the junction and pivotable between first and second positions for initially guiding a vehicle in a respective one of two directions upon the vehicle entering the junction from the junction first end. A fixed, guiding .[.means.]. .Iadd.structure .Iaddend.is positioned between the movable guide rail and the second guideway portion and is operable to guide a vehicle through the junction and onto the second guideway portion upon the vehicle being initially guided by the movable guide rail while the movable guide rail is in its first position; and another fixed, guiding .[.means.]. .Iadd.structure .Iaddend.
