Id argue the northeast corridor is effectively the only place we have intercity rail.

While there are other routes, it’s mainly just keeping the lights on. How can rail be useful at 1-2 trips/day, travelling at glacial speeds? We shouldn’t even count it. If we ever start funding rail seriously, we’ll save a crap load of money where Amtrak kept the right of way sort of in use but that’s the only benefit.

The 2022 infrastructure bill would have made a huge difference increasing several routes to “sort of useful”, but even then a decent rail system would be a century out
