What are those trains called?

Question

The kind that "float" above the magnetic tracks.

Answer 1

Indeed, these types of trains are called Maglev (magnetic levitation), which use magnets and high powered motors to propel the train on a cushion of air above the "track" structure.  While a very environmentally friendly and fast mode of transportation Maglev is still in the developmental stage and has a long way to go before it is efficient and cost effective enough to replace traditional electric and diesel-electric locomotives used to power trains.

Answer 2

trams

Answer 3

Bullet trains.

I was thinking and answer and said it out loud before i even read the rest of the question, haha.

I think that is a specific kind of train in Japan, for more types of trains: http://en.wikipedia.org/wiki/Train

Answer 4

They used to be called linear induction trains, but now they are called magnetic levitation trains, or 'maglev' for short.

Maglev (short for "magnetic levitation") is correct.  A Bullet Train has wheels and runs on rails, just at a higher speed than usual.
