Maglev is a system of train transportation that uses two sets of magnets, one set to repel and push the train up off the track as in levitation , then another set to move the 'floating train' ahead at great speed taking advantage of almost no friction. Within certain "medium range" locations (usually between 200-400 miles) Maglev can compete favorably with high speed rail and airplanes.
