Here it comes, the fastest land transportation there is---Japan's linear motor car. No wheels, no engine, no exhaust. Electro-magnetic power makes the train float a few inches above the rails and also propels it forward.
If you can lay your hands on two magnets, you can use one to push the other across a table. That same principle--North pole opposing South pole or vice versa--when magnified to vastly superior heights of sophistication runs this train.
As the old joke goes, it takes three people to see it: one to yell, "Here it comes" while the second one yells, "Here it is" and the third person screams, "There it goes."
