A Maglev train floats about 10mm above the guidway on a magnetic field and is propelled by the guidway itself rather than an onboard engine by changing magnetic fields. An exotic proposal based upon this principle is the Trans Atlantic vactrain: a Maglev train in a long near-vacuum tube with speeds that allow less than one hour travel times between New York and London.

clipped from www.ecofriend.org clipped from www.o-keating.com The principal of a Magnet train is that floats on a magnetic field and is propelled by a linear induction motor. They follow guidance tracks with magnets. These trains are often refered to as Magnetically Levitated trains which is abbreviated to MagLev. clipped from www.youtube.com clipped from en.wikipedia.org Vactrain
A vactrain is an exotic, as-yet-unbuilt proposal for future high-speed railroad transportation. This would entail building maglev lines through evacuated (air-less) tunnels. clipped from en.wikipedia.org Transatlantic tunnel
