The Meissner effect has a lot of potential even outside of the energy efficiency changes (which is by far the most important).

It will be fun to see trains levitating over the ground without any friction loss from the wheels at high speed.

Isn't majority of energy lost spent on pushing air away when we talk about high speed trains

yes, but friction of the track is also a big factor.
