I am 100% sure the way Japan designs high-speed rail is to draw the nose first, and then figure out how fast the rest of the thing could go. We beat them in a war. Why do they have this, and we get Acela?https://arstechnica.com/cars/2019/05/japanese-railway-company-starts-testing-249mph-bullet-train-speeds/ …

This is exactly why the Acela can’t reach top speed but for 20 miles of the route from Boston to DC. Old tracks with too many turns.

This isn't really an answer—everyone with high speed rail ended up building special rights of way. No fundamental obstacle to that in the US either. We did it for interstate highways, but not rail.

In kind of is really. If you don’t have the political will and local buyin (also the federal one in the US case) it’s impossible to bulldoze and build a new route to get this. And yes the TGV has that and ICE etc etc. I mean how could you get Amtrak to build a fast trainline?
