If you can't think of another city in Nevada off the top of your head, are you even American? (Reno.)
Anyway, New York to Las Vegas spans most of the US. There are plenty of routes in the US where rail would make sense. Between Boston, New Haven, New York City, Philadelphia, Baltimore, and Washington, D.C. Which has the Amtrak Acela. Or perhaps Miami to Orlando. Which has a privately funded high speed rail connection called Brightline that runs at 200 km/h who's ridership was triple what had been expected at launch.

Which proves that when the will is there, it will be done. The only impediment in other places is simply the people not wanting it. If they wanted it, it would already be there.
The US has been here before. It built out a pretty good, even great, passenger rail network a couple of centuries ago when the people wanted it. It eventually died out simply because the people didn't want it anymore.
If they want it again in the future, it will return. But as for the moment...
