Track junction points for combined road-track vehicles - has frog movable across one track width, contoured by cross stems

摘要

The double or multiple junction points are on guiding tracks for dual-system vehicles which can also run on roads, with cross-guiding stem pieces on both sides of the track, and movable sections of such stems in the crossover area. In this crossover area (13) there is a points frog (8), movable horizontally across a track width (12), to cover the not needed part of the crossover. This is contoured parallel to the line of travel by the course of the cross stem sections (9-10) corresponding to the intersecting tracks (1-3). In triple points the frog can be divided lengthways corresponding to the course of the centre tack, with both pieces individually movable and fitted with stem sections along the division.
