MagLev Trains
Posted in Models, RDAG by Kate Archdeacon on December 3rd, 2008
A maglev, or magnetically levitating, train is a form of transportation that suspends, guides and propels vehicles (predominantly trains) using electromagnetic force. This method has the potential to be fast and quiet when compared to wheeled mass transit systems, potentially reaching velocities comparable to turboprop and jet aircraft (900 km/h, 600 mph).
The highest recorded speed of a maglev train is 581 km/h (361 mph), achieved in Japan in 2003, 6 km/h higher than the conventional TGV speed record (Wikipedia). Due to the reduced friction compared to conventional trains, there is great potential for them to use less energy and to therefore have a low emission intensity. Due to their high speed, and the fact that wheels are retracted, the greatest challenge remaining for maglevs is to reduce air friction and to reduce costs. Maglevs require a considerable investment in technological know-how and infrastructure, but may be able to provide high speed and relatively low GHG intensive mobility for residents of densely populated areas.
