US rail is so pathetic. Not the rail’s fault per se, but it's pretty embarrassing for a a supposedly wealthy country to not be able to offer its citizens cheap, easy, high speed travel across the country.
Much of the actual wealth is in the northeast corridor, where the Acela is improving the quality of their product, and in California, where Southern CA and the Bay Area both have fairly nice regional trains that go as fast as the right of way will let them. I think we've done OK connecting places that matter, and as flying continues to enshittify and people will choose rail for comfort.
