High-speed rail demands extremely precise rail alignment and a continuous maintenance program.
The train doesn't touch the rails (by several inches) while it is moving...thats the 'LEV' part in MAGLEV
Maglev relies on the aerodynamic flow between train and track to generate a "cushion" on which the train rides. At low speeds, this cushion is inadequate or nonexistant.
Maglev uses electromagnetic repulsion from two similar polarities to create lifting force, (and motive force) weather it is moving or not... that's the 'MAG' part in MAGLEV
