Good. With that out of the way, time to build some trains.

  The question is, can trains work on batteries or hydrogen or do we need the electric infrastructure, all those cables above it. Also, do we really need tracks? Can't we just make a dedicated road with self driving cars or buses, which is possible on a dedicated road even today?

  And tracks too, don't forget the tracks! :-)
