I have never been able to ride on one of these but it is definitely a dream of mine to travel by high speed magnetic train. They use massive electronic magnets to float the train and move it incredibly fast. Over time they have gotten much faster and now things like hyperloop are going to move traincars MUCH faster at speeds that we can hardly imagine. Soon it will take less than an hour travel immense distances, across the world without needing planes and gasoline.
