Country size is irrelevant for two reasons:

- most travel is within the local polity, e.g. suburbs to work & back, social activities, etc. The radius for these is not hugely different between the US and the EU.

- it's the European train network at this point, not one country's, and it needs to be one US system too, not one state's.

Yes, trains are hard in the US Midwest. But not on the west coast, and not in the larger east coast area either.
