Our Institute has developed the solutions to the critical problems pertaining to VacTrains and has registered Swiss and international patents. The principles and the basic design are vital for all VacTrain systems. They will be made available to the SwissMetro-NG project.

The VacTrain Switch, for example, permits vehicles to change direction by guiding them from one track (or direction) to another without having to stop and without having to leave the vacuum. Without a switch any transportation system would only be able serve stations along a line or loop. It would fail to fulfill its purpose. Our switch  is the only solution available for switching VacTrains. It permits unrestricted drive through speeds in one direction and very high speeds in the other (over 200 km/h). Most important is that it permits the construction of networks to serve whole countries or continents, similar to the highway or railway networks.

The VacTrain Gate permits passengers to cross the vacuum gap between the vehicles and the wall of the pipes / tunnels at stations in comfort and safety. It is extremely quick (10-20 seconds) especially in comparison to the gates / sluices proposed by other systems (over 1/2 hour).
