When you factor in that you need a car in both your departing city and destination city (except for NYC), AND the fact that nearly every household in those regions owns one or multiple cars (which is not true in higher density/higher urbanization countries)...it begins to not make sense especially given the massive upfront cost of construction.
Rail is not going to happen until you don't need a car in those cities. Chicago you could do, but the others are not pedestrian friendly. Anyone traveling within that region will have a 95% chance of already owning a car. Unless the train gets you from Chicago to Minneapolis in an hour, people are just going to drive. The risk with car rental and money spent on Uber's isn't worth it.
I feel like these types of comments come from people that live in NYC or LA. The rest of the country is so fuckin sparse. Your "walkable cities" idea doesn't make any sense and is completely unfeasible outside of major metro areas which land wise in the US is like 99%.
Also for the record, the overwhelming majority of the US population lives in metropolitan areas, not rural ones.
I've done Chicago -> Madison by bus, and honestly prefer it to the plane at least (even from the airport). More comfortable seats and I get out just at a station. High frequency bus lines feel like good indicators of where some trains could work, and it's not like bus services are dead.
(Similarly, I did Portland -> Eugene on Amtrak and it was nice and chill! I roadshared to my final destination but I had to get from A to B somehow)
- For France, rural areas don't really have that good of a rail network. Instead there are several trunk lines that are reliable. But it means that east-west stuff is nearly non-existent. Lots of "drive me to the station and drop me off please". Good enough to put France at number 2 in numbers of km ridden per passenger!
- For Germany, the network is much more evenly spread out. But ever German I've met complaints constantly about the unreliability of the trains, combined with the low rate of service. So you end up with stations everywhere, but if a train gets cancelled you could be stranded for hours.
Anyways I do think the French model makes a hell of a lot of sense (prioritizing train frequency over coverage), but it might not be what people are expecting if they just look at a map of trains.
This may be true when averaged across the entire country (or even just the lower 48).
But it is absolutely not true if you consider various zones of the country as candidates for good rail service.
Several such zones exist, among them:
1. the north east corridor, perhaps one of the largest and densest conurbations in the world
2. the roughly rectangular shape formed with the NW corner in Minneapolis, the NW corner in Milwaukee, the SE corner in Detroit and SW corner in <wherever the hell that is>
3. The triangle in Texas formed by Dallas/Ft. Worth, Austin and San Antonio
All 3 have higher population densities than those found in non-urban parts of Europe; the latter have good to excellent train service, but none of these 3 do.
