I find it hard to be enthused for trains, trams, and busses any more, since discovering over 20 years ago that clean energy and many other technologies and man-made innovations have been suppressed to maintain out dependence on scarce polluting energy because it's easier to put a meter on to extract rents by. ... So much so... y'know we could have had spaceships each since the 1930s? T Townsend Brown was not the first nor the leading pinnacle. Even back to the mid 1800s, when they were rigging their hot air balloons with faraday cages and high freq e.m. fields to reduce, and even eliminate inertia [... 1 small vacuum-proofing hop, and you have rudimentary interstellar flight capabilities]... ... we never needed rockets, we never needed planes. ... we don't really need buses either. Or cars.

But if we make a nice world, buses still could be very nice to have.

Semi-subway trains too.

And cars even too. Track day, anyone? :)

Whole lot of vertical space unused in this world [and beyond]. We have so much headroom without the crooks holding us down. Heck! Even the crooks, even with their billions and trillions, would be better off, if we availed, each and all, all the emancipatory technologies.
