The evolution with trains could be very interesting in the next years. Levitating trains are a very interesting concept and in the past scientist have already uttered the possibility of high speed Maglev trains crossing the Altantic much faster than the Concorde did.

A 4,000-mph magnetically levitated train could allow you to have lunch in Manhattan and still get to London in time for the theater, despite the 5-hour time difference. It’s not impossible: Norway has studied neutrally buoyant tunnels (concluding that they’re feasible, though expensive), and Shanghai is running maglev trains to its airport. But supersonic speeds require another critical step: eliminating the air — and therefore air friction — from the train’s path. A vacuum would also save the tunnel from the destructive effects of a sonic boom, which, unchecked, could potentially rip the tunnel apart.

This video of a toy Maglev train shows the amazing technology we will maybe adapt over the next years.
