>>2023278I've seen a couple new rail projects in the New York tristate, so I don't think it's a dead dream. A transcontinental highspeed rail is far off, but you can definitely do coastal highspeed and possibly a Great Lakes project. Best way to do it in my opinion is for the federal government to build as much of it on the leftmost lanes of interstate highways by offering states a lease they couldn't refuse and build a train line that would connect at least from Boston to Atlanta and another from San Diego to Seattle.
I'd also do a slightly narrower gauge so as to not take up as to minimize the road use.
