4.1.2.2.10 Viennese Bend Transition Segment

The Viennese Bend (R) transition segment is a kinematic high performance transition. The horizontal curvature is assembled by the baseformula and a term depending on the height of the gravity center line relative to the track plane and by the applied cant values at the start and the end of the segment.

The x/y coordinates can be calculated using a 7th order polynominal spiral.
