In 1974 a refinement of the concept was developed for the Yverdon–Ste-Croix railway in Switzerland. Unlike the Langbein system, the Vevey system requires no manual intervention to fix the standard gauge axles over the narrow gauge bogies. In this system, rather than the axle being supported, the wheel flanges of the wagons are cradled in brackets projecting from the side of the "Rollbock". This lowers the centre of gravity and increases stability. Many modern "Rollbock" users have converted to the Vevey System. The Vevey Technologies company was bought by Bombardier in 1998.
