What energy is lost is mostly due to the friction between the wheels and and the track, and the friction between the train and the air (i.e. air resistance). Magnetic levitation (MagLev) trains solve the first of these; they have no friction between the trains and the tracks because the train does not touch the track. Instead it hovers above it due to electromagnetic repulsion between the two. MagLev trains are therefore much more efficient and capable of greater speeds than ordinary trains. MagLev trains have been in use for decades. The second energy-drain, air resistance, can be eliminated by housing the MagLev train in a vacuum.
