Well JT I had you down as our resident trains expert but no longer.
You cannot build around anything if you want a truly high speed line.
It has to be as straight as possible.
Osbourne when chancellor demanded the line avoided his families country pile in Cheshire .... there was uproar from the engineers and planners as a large curve would have to be built into the track.
How that little episode ended I don't know because of a clear lack of any real interest.
I'm sure you could Google it though.
HS lines do not have curves bends and build arounds.
I think you'll find that high-speed lines do have curves, although the curve radii are so small most people wouldn't notice.

Watch the vid for a few minutes. The train is going at 350km/h. Still slight curves though.
Look, guys. If you want to troll the thread, give me a reason for being here?
