i have seen when liquid helium is poured on a magnet, a second magnet can be kept hovering or pulling/pushing each other at will, Is it possible using this technique to design an engineless transportation system?

Walk, don't run, to the Wikipedia. Actually it's called a Mag Lev and there are several in existence and operating in Japan, China, Germany, and Norfolk Virginia.

That is one way to do it. In Japan, and maybe in Europe there are magnetic levitation trains. The tracks as well as the train have magnets that have alternating polarity. This keeps them both pulling and pushing away at the same time, keeping the train at the same height. If I remember correctly the tracks are computer controlled and the polarity changes propelling the train.

sure...but it will loose its magnetic field once its cooled down.
