Levitation. Maglev trains have no contacts with the rails while they move forward. They are levitated on the guide-way with the help of magnetic forces. Levitation is the process by which an object is suspended against gravity in a stable position without any physical contact.
The Shanghai Maglev Train (or Shanghai Transrapid) is a maglev line that operates in Shanghai, China. It is the first commercially operated high-speed magnetic levitation line in the world. The original plan to extend the maglev line to create the BeijingâShanghai High-Speed Railway was eventually shelved in favour of conventional high-speed technology, leaving the existing 30km maglev line between Pudong International Airport and Longyang Road, Pudong. Construction of the SMT line began in March 1, 2001, and on 1 January 2004 it began test operations. The top operational speed of the train is 431 km/h, making it the world's fastest train in regular commercial service since its opening in April 2004. During a non-commercial test run on 12
