Wiener Bogen curves

Keeping railway projects in line

This invaluable technology improves the layout of the railway line in curves significantly. Instead of traditional clothoid curves, the transition from the straight to the curve in the track is designed as an interaction between the centre of gravity of the vehicle and the curve element. This greatly reduces the lateral acceleration and the cost of maintaining the curve.


Working alongside the proprietor, koocoo is currently investigating how to demonstrate other economic and technical benefits of the Wiener Bogen.

International market launch

Discussions with interested parties are under way in the target countries of Switzerland and Germany.
