Abstract (en)

[origin: WO9828492A1] The invention relates to a curve path of a switch comprising a switch rail, main track and a diverging track, whereby the curved track consists, from the start of the curve until the end of the curve, of several sections with different curvatures 1/R, where R is the radius of curvature. The chosen coefficient of curvature is alpha = 1/R / 1/Rmin at the start of the curve path ( alpha A) and >/=0 at the end of the curve path ( alpha E), and the point or an area in which alpha = 1 is at a relative distance nu = L/Lges NOTEQUAL 0.5 from the start of the curve path, where L is the distance from the start of the curve path and Lges is the length of the curve path.
