Cross-guide stemmed converging tracks - have functionally active points with tongue flanks matching meeting tracks, and additional stem section

摘要

The functionally active junction points are for tracks with a horizontal wheel running surface and vertical transversely protruding cross-guiding stems on both sides of this. Two tracks coverge at an acute angle at the points and cross over into a third common track. Where the tracks intersect there is a points tongue swivelling about a vertical axis with side flanks as interfacing movable cross guiding stems, contoured like the first or second tracks and its swivel axis between these outside the running surfaces, while its movable end faces the third track. Additional interchangeable sections of cross guiding stems are fitted inside the area adjacent to the third track, where the centre lines of the first two tracks have diverged by less than the requisite min. thickness of the tongue.
