Does anyone know any fun facts about the Maglev?

Doesnt run on tracks. It uses Magnetic Levitation (so it hovers around the main rail) to gain movement. This method has the potential to be faster, quieter and smoother than wheeled mass transit systems The technology has the potential to exceed 4000 mph (6437 km/h) if deployed in an evacuated tunnel. The highest recorded speed of a maglev train is 581 km/h (361 mph), achieved in Japan in 2003 This is slower than aircraft, since aircraft can fly at far higher altitude where air drag is lower and thus high speeds are more readily attained.

horrendously expensive and only a tiny bit faster than conventional high speed rail. not a good bargain for your transportation dollar (or billion dollars)
