Swissmetro is an innovative magnetic transportation concept of high speed trains running inside partially evacuated underground tubes with speeds between 300 and 500 kilometres per hour. Some experts see Swissmetro as a promising alternative to both air and ground high-speed transportation.
According to Swissmetro Company SA, the industrial development phase on the electro-mechanical and mechanical systems will start soon and a pilot line of about 15 kilometres will be developed "as soon as possible".
