Abstract
In the paper an attempt has been made to focus on shaping the variable curvature in the diverging track of the railway turnout. Basing on some earlier studies, solutions provided with a circular arc in the mid-zone, and in the extreme regions with segments of non-linear curvature of equal length and zero curvature at the start and end of the turnout, have been assumed as models. The most advantageous type of curvature has been chosen taking into account the kinematic conditions. The presentation made includes an analytical record of the curvature and the tangent inclination angle in the diverging track length and the Cartesian coordinates of the track. The final part of the paper referred to the determination of a set of basic values relating to geometric parameters appropriate for a given speed of trains and adequate for ensuring the minimization of the length of the entire turnout at a given final ordinate.
