Maglev trains (short form of magnetic levitation) are a very fast type of high-speed rail. Magnetic levitation is a technology that uses magnetic fields to make the train move. These fields lift the train a small distance above the tracks and move the train. They are much faster than regular trains. A transcontinental "maglev" trip from Toronto to Vancouver might take three hours. This trip takes three days on a regular train. Some day, people may be able to travel faster across land on a "maglev" train than they would in an airliner. The highest known speed of a "maglev" train is This was done in Japan in 2015. As of 2019, a few lines, only a few km or miles long, are carrying passengers in China, South Korea, and Japan.
