I tried to make it fairly realistic. Obviously I would like HSR absolutely everywhere, but a line through middle of nowhere Montana probably would not see much ridership and would come at extreme cost (especially in the mountains).

    IIRC I clocked that NY-LA line at something like 14 hours with medium HSR and down to 10 with the newest shit that can run on steel. In either case it’s plenty fast for a sleeper train. There’s also a pre-existing corridor, and, most importantly, massive population centres: A sleeper each direction each day won’t nearly be enough to cover demand but that’s no biggie you can spread them out and e.g. have people get up or start sleeping at Huston (allowing them to get on and off) or let them sleep through the whole of Texas. That’s already three trains each giving the passengers even more possibilities.

    You probably want to close the middle traverse from Colorado to Oregon and then connect to whatever the Canadians are doing east-west, but that doesn’t mean that the southern corridor doesn’t make sense in isolation.

      NY to LA will never be 14 hours with current or near future technology. Its 50 hours from Chicago to LA with the slow trains and while high speed rail is a significant improvement its not crazy enough to get speed increases like that.

        About 4500 km on current roads, that’s at least in the right ballpark for rail. The currently highest-rated rail route is in China, 350km/h, that’s 12.8 hours. Canada is currently building to that spec. TGVs can go 574.8 km/h (yes, on steel), that’d be 7.8 hours… 10 hours would be a mere 450km/h, I think that’s perfectly doable in ordinary service, on steel, if you have the will. A bit faster than a Bugatti Veyron why is that so hard to believe steel has quite some advantages over rubber on asphalt.

          That assumes the train is traveling at its maximum speed for the entire duration of the trip-- which is almost never the case, even in China. For a route that long with many many stops large portions running over rough terrain necessitating curves and grade changes the actual average speed along the route would certainly mean the average speed of the route would be much slower.

          Ultimately, spending a tremendous amount of money embarking on an ultra-high speed rail route between the coasts-- which would certainly be one of the most ambitious infrastructure projects in human history-- would be a waste of time and money compared to almost any other rail project. All that money would be much better spent on high speed rail where it actually makes sense, and on conventional rail connecting every city in the US.

            Night trains don’t tend to have many stops, less than ordinary HSR ones. And really all that empty space in the US should lead to the average speed being quite a bit higher compared to maximum when compared to Europe. But, all that said, don’t nail me on the details. Even if it’s a 16 hour trip, there’d still be plenty of people who would be interested.

            And then, well, LA-Huston and NY-Huston make sense independently so the track is already there.

            and on conventional rail connecting every city in the US.

            Bombardier Talent 3’s are technically HSR, given that they max out at 200km/h. Tracks and rolling stock supporting on the order of 150km/h aren’t a rarity for S-Bahn systems, here, that’s more like commuter rail. Meanwhile, Amtrak is running trains over vast sections at more like 50km/h because the track is so shoddy you can’t go any faster. (That’s a sensible average speed for subway systems…) Those vast sections have to be rebuilt, anyway, and while you’re at it you can just as well build them to higher standards as the cost increase is almost negligible compared to what building non-shoddy track costs.
