Magnetically levitated (maglev) trains travel at speeds of up to 300 miles per hour. They achieve this speed in part because they do not touch the rails. These trains are lifted, propelled, and guided by magnetic forces, so there is no friction between the railcar and the track. Maglev trains are still in development, particularly in Germany, Japan, and the United States. Because of their cost, governmental support is required to develop the maglev trains.
