Maglev train

[technoguy]

Magnetic levitation transport, or maglev, is a form of transportation that suspends, guides and propels vehicles via electromagnetic force. This method has speed and ride comfort advantages compared to wheeled mass transit systems - potentially, maglevs could reach velocities comparable to turboprop and jet aircraft (500 to 580*km/h), and the lack of track-wheel friction allows for exceptional comfort - but although the idea is decades old, scientific and economic limitations have hindered the proliferation of the technology.
