How are Maglev trains accelerated and stopped?
They are accelerated and stopped by energizing/de-energizing the magnets built into the track in sequence. One magnet pushes the train forward and then a fraction of a scond later the next magnet either pushes it faster or slows it down. Maglev is horrendoudly expensive to build, it uses no existing infrastructure or equipment. HIgh speed conventional rail is more efficient, is able to use existing infrastructure by upgrading, is just as fast and is much much cheaper to build.
