Abstract: A method and system are provided for opening and securing a railroad frog. The system is provided with a body member and a plurality of attachment members, which are selectively securable with the body member. The attachment members are structurally configured to secure to different structural features along spring wing rails and fixed structures positioned opposite the spring wing rail. Manual actuation of a tensioning mechanism that is coupled with the body member advances opposing first and second attachment members toward one another, moving the spring wing rail into an open position. Wedge members, coated in a non-slip material are provided as an additional means for securing the spring wing rail in an open position.

Abstract: A spring rail frog is disclosed that includes a movable wing rail, a fixed wing rail and a nose rail. The movable wing rail is provided with a bendable portion and a non-bendable portion. The bendable portion can include any or all of a reduced width base portion, a reduced width head portion and an increased width web portion. The height of the movable wing rail can also be smaller in height than the height of the nose rail. A fixing plate can also be provided between a base plate and the movable wing rail to adjust the relative height of the movable wing rail and the nose rail.

Abstract: A railroad trackwork spring frog installation having a conventional wing rail with attached wing rail horn fitting is provided with an improved co-operating hold-down comprising a weld block element component, a separate, readily replaceable, riser component supported by the weld block component, a housing component positioned over the wing rail horn fitting and supported by the weld block component, and bolt-type fastener devices joining the hold-down components into a unitary structure.

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: A railroad frog has either a cast or rail-built point, resting on a baseplate which is fastened to ties. A pair of heel rails are attached to the point, to the ties and to traffic rails. A pair of movable wing rails extend from the toe of the frog to a location adjacent the point of the frog. At the frog point an open wing rail forms a flangeway with the point, while the other, closed wing rail cooperates with the point to form a continuous tread surface through the frog. The wing rails are alternately thrown between the open and closed positions by an actuator. A series of stops define the open wing rail position and act to hold down the open wing rail. The wing rails have hinges which allow them to move. The wing rails have a full rail base at the hinges. Adaptor plates allow use of the frog on concrete ties.

Abstract: A rail switch in which two wing rails are engageable with a frog in alternation, characterized in that guide members are provided, which are held in position relative to the wing rails and extend under and are engageable with the frog or parts rigidly connected to the frog to prevent an upward movement of said guide members.

Abstract: Railway switch for Vignoles rails, comprising a frog tip and a pair of wing rails arranged for swivelling movement, one of said wing rails engaging the frog tip in its end position and being supported in this position in direction of engaging the frog tip by means of movable supporting members resting against the railway sleepers, noting that the movement of the supporting members and of the wing rails is being effected in mutual dependence, that the supporting members are guided on the railway sleepers in longitudinal direction of the corresponding wing rails and are cooperating with abutments protruding from the wing rails and preferably being fixed to the web of the wing rails, and that the supporting members are formed of one supporting rod for each associated wing rail, said supporting rod comprising, in addition to the supporting surfaces serving for supporting the abutments, recesses giving free the wing rails, characterized in that the push-rod serving the purpose of switching over the railway switch

Abstract: Railway switch for Vignoles rails, comprising a frog tip and wing rails arranged for swivelling movement, each of the wing rails engaging the frog tip in a respective end position and being supported in this position by supporting members resting against the railway sleepers, the movement of the supporting members and the movement of the wing rails being effected in mutual dependence, the supporting members being guided in longitudinal direction of the corresponding wing rails by guide members on the railway sleepers and the supporting members cooperating with abutments protruding from the wing rails and fixed to the web of the wing rails.
