Switch devices made by VAE VKN offer state-of-the-art quality. The diverging path geometry of our switches is optimised according to the principles of vehicle dynamics. This cuts induced forces and thereby improves travelling comfort and service life. The use of highly wear-resistant materials together with most advanced production technologies facilitates the practical use of the knowledge gained from EDP-supported simulation programmes. Products made by the VAE-group meet also the requirements of the Technical Specification for Interoperability of Directives 96/48/EC and 01/16/EC for European High-speed Rail Systems.
