Too many moving parts at high speed
"...the designers at Priestmangoode argue that existing plans for high-speed rail would involve a costly and environmentally damaging network of new train stations. They say that high-speed trains also waste energy and time by having to continually speed up and slow down to stop at stations."
And building the extra infrastructure to allow trains to "mate" at 200-mph wouldn't be as "costly and environmentally damaging"?
Lemme guess, this design firm is paid with tax dollars to come up with expensive and unworkable ideas. Wish I could get paid to do that.
