Depends on the train, but what do you mean? Do you mean self driving?
my question is more or less, what does the future look like over in rail-based transit?

Hopefully more trains in more places, going up to about 300km/hr. Not sure there’s a general theme beyond that. Economics currently runs out past 300km/hr with existing technology.

what does "runs out" mean here?
-
Increased cost required to power train through increased air resistance (or align trackway) not usually worth benefit in travel time reduction. A lot more power to save five minutes.

I imagine the answer is "planning gridlock", at least in most parts of the US.

The rail is obsolete. We don't need rails to guide the cars.
