The article describes the so-called Wiener Bogen® (Viennese Curve) and its non-linear cant ramp. Some of its geometrical and kinematical parameters have been analyzed, including curvature and shape of the cant ramp. An example of calculations has been provided with results shown in both tables and graphically. The possibility of modernization of the existing railway curves with clothoids or cubic parabolas by replacing them by curves with Viennese Curves has been initially discussed.
