that is because maglev train does not run on the wheel it run on the magnetic field repulsion which able to lift the train above and friction does not reduce the speed

in normal trains the wheels are in contact with the rails while in maglevs on the principle of repulsion it literally floats over the rail without touching it and there is almost negligible friction in them this link may help you..... https://en.m.wikipedia.org/wiki/Maglev
