The STR-Institute has developed solutions for the critical problems pertaining to vacuum-trains. Patents for the key inventions were either already granted or are still pending in all relevant countries of the world. The principles and the basic design are vital for all vacuum-trains. They will be made available to the SwissMetro-NG project.
The VacTrain® Switch is analogue the railway switch. It 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 in the pipes / tunnels. It permits unrestricted drive through speeds in one direction and very high speeds in the other (over 200 km/h). It permits the construction of networks to serve whole countries or continents.
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).
