The paper deals with the issue of shaping a variable curvature in the diverging track of the railway turnout. Solution without a circular arc in the central zone, comprising two zones of non-linear curvature, of the same length, having zero curvature values at the end points, was adopted as a model, on the basis of the previously conducted dynamic tests. Optimum type of curvature was selected from the point of view of the kinematic conditions. An analytical record of the curvature and of the tangent inclination angle along the diverging track and of the Cartesian coordinates of the diverging track are presented. Obtained theoretical correlations were verified by computing. Verified correlations were used to determine geometrical parameters of some turnouts with non-linear curvature of the diverging track for different assumed train running speeds on the diverging track. The criterion was to minimize the length of the entire turnout having predefined ordinate of the end of its diverging track.
