and we know little about it. There are two types of trains - one run in Germany (EMS - electromagnetic suspension: rails are ferromagnetic, trains is equipped in magnetic soil, which suspends it above the surface 150 mm above the guidewave). The train is propelled by alternating current pulses. Another system called electrodynamic suspension (EDS) works some Asian countries (China, Japan, South Korea). It relies on superconducitivity, these materials are placed on the sides of the rail and interact with the guidelines of the train placed on the side. The superconductive material form a letter "8" with some part of the coil asking as attractive force and some as repulsive force to the train - thus suspending it above the ground. These trains are very fast since superconductivity creates almost no friction. Here is a guy explaining it:
