or:No, unless they run in a tube with a vacuum. The air friction would heat the front of the train red hot, same as what happens with the SR-71 Blackbird
or:The train floats atop this magnetic field and is given support and guidance from the interaction that takes place between the magnet and another element on the ground, such as a steel track, a conducting element in the track or another magnet. Elimination of direct mechanical contact they can reach higher speeds.
