Trains have been proven to be able to go at least 375mph [0]. That would make NYC->SF take 6.9 hours to travel the 4162 km. The current average flight time from NYC to SF is 6.7 hours.

So, it's at least technically possible.

China is doing R&D on a partial-vacuum train (basically Musk's hyperloop thing) with a target of 1,243 mph[1]. That's probably a pipe dream, but worth mentioning nonetheless.

I'd be okay with this if all the taxpayers were granted equal shares that their collective money could have purchased at an imputed no-bailout price.

What's your source for this? I take this flight a lot and I find it hard to believe it's more than 5.5-5.75 on average. Looking at the last few weeks for one of them[0] supports my experience.

Maybe your number has TSA/airport time included.

That's straight math. Not assuming any stops or slow downs.

According to Gemini this hypothetical train would take about 18 hours.

It would also cost hundreds of billions of dollars and a decade to build.

Doesn't do much for seeing Uncle John next Tuesday.

I like trains. I like them a lot. But they don't work over long distances. Particular when you have dozens of state and city jurisdictions to cross.

Each of them get a vote.

Honestly I'd be happy just to have quality HSR on the East Coast. Boston to Richmond takes like 12 hours right now.

Maybe the West Coast could get a Seattle to San Diego route.
