It was tested successfully by the Applied Superconductivity Laboratory, and could further increase the speeds of commercial high-speed trains. Pictured is a student going for a test ride -- This travelled at a rather mundane 26 miles (42 kilometres) per hour. It was not until the turn of the century, though, that high-speed maglev would come into commercial operation, mostly in Japan and China.
