Well I wouldn’t object against not doing it underground, I just think that grade separation would be useful there’s more than one way to skin that particular cat.
or highspeed as frivolous requirements that serve to stop the project altogether (anything over 120 km/h, let’s say).
There’s plenty of Bombardier Talent 2 on S-Bahn duty in Germany, doing 140km/h, Talent 3 can do up to 200 which is technically HSR, same goes for the Stadler Flirt.
That is: You can get those things off the shelf. Building track capable of supporting those kinds of speeds doesn’t really cost much on top of what you’re paying for new track in the first place. At the very least you should make sure that, where it wouldn’t explode costs, curve radii etc. are suitable for HSR.
