Maglev trains, or magnetic levitation trains, are a type of high-speed transportation that uses powerful magnets to lift and propel the train above the tracks. This eliminates friction, allowing the trains to travel at much higher speeds than traditional trains. They can reach speeds of over 300 miles per hour, making them one of the fastest forms of ground transportation. The technology behind maglev trains involves two sets of magnets: one set repels the train from the track, while the other set propels it forward. This innovative system not only increases speed but also reduces wear and tear on the train and tracks, leading to lower maintenance costs.
