As far as I know, this uses superconducting technology, as it's the only way to get the huge currents needed for the huge magnetic fields needed to levitate an entire train.
Because of the way that superconductors work, you can also use them as shielding of magnetic fields, because they expel magnetic fields from themselves, so that could be how it's done.
