Since 1972 three European companies, AEG-Telefunken, Brown-Boveri and Siemens have been working together to realize a new type of non-polluting fast train. The test vehicle is 12 m long and 4 m wide, and weighs 17 tons. It is equipped with a 3200 kg linear induction motor of 4.7 MVA, and 8 superconductor electromagnets of 500 kg each. These through fluid helium superconductor coils are put under direct current and short-circuited afterwards. They cause large magnetic fields bringing about a lifting height between 100 and 200 mm. The vehicle is equipped with 16 wheels with pneumatic tyres, used for starting and landing. The practical tests were convincing for a lifting height of 100 mm at a speed of 140 km/hour. The authors outline the basic principles of electrodynamic repulsion. They describe the conception of the magnetic system used on the vehicle, and deal with specific details proper to the propulsion motor.
