Transrapid is a German high-speed monorail train using magnetic levitation. Based on a patent from 1934, planning of the Transrapid system started in 1969. The test facility for the system in Emsland, Germany was completed in 1987. In 1991 the technical readiness for application was approved by the Deutsche Bundesbahn in cooperation with renowned universities. Its current application-ready version, the Transrapid 09, has been designed for 500 km/h cruising speed and allows acceleration and deceleration of approx. 1 m/s2. In 2004, the first commercial implementation was completed. The Shanghai Maglev Train connects the rapid transit network 30.5 km (19.0 mi) to the Shanghai Pudong International Airport.
