How long have maglevs been around?

Answer 1

Maglev trains, which use magnetic levitation to operate, have been in development since the early 20th century, with the first successful prototype demonstrated in the 1970s. Commercial maglev services began in the 1980s, with the world's first operational maglev line, the Birmingham Maglev, opening in 1984. Since then, several countries, including Japan and China, have developed advanced maglev systems.
