Amtrak Might Bring 200+ MPH Japanese Bullet Trains To Texas

Everything about trains and railroads
It says it will bring the trains, not that they'll actually go to 200 mph
Of course; we don't doubt the promise. What I doubt is that the US has enough electrified track in good condition for the trains to hit 320 km/h.
I'm more doubtful that the Texas power grid can support these trains.
