True, but we have this thing called "high speed planes". Gets you there even faster than rail.
If you want to take a train and you've got time to kill, take Amtrak.
high speed rail is overrated. Tickets cost as much or more than an airline ticket, but even going at 300km/h, it takes 2 or 3 times the amount of time to travel. Even more if you have to make frequent stops to embark and disembark passengers.
