Swissmetro
Swissmetro was a futuristic Swiss national transportation project using vactrain technology. It was put forward by Marcel Jufer of the École Polytechnique Fédérale de Lausanne.
The trains would have significantly lowered the travel time between major cities in Switzerland. For example, the time between Bern and Zurich could be reduced from the present 60 minutes by intercity train to a mere 12 minutes.
