> Max line speed of HS2 is 360km/h, with provision for 400 in some sections in future.

That's already been reduced to 320 km/h under this year's "HS2 reset". Which I imagine in reality will be 300 km/h normally at most, with even lower speeds seen day to day

Interestingly the written report to the government stated "However, no railway in the UK, or globally, is currently engineered for 360 kph". Are you incorrect or did they forget to include China in their research?

Anyway, I thought these were last decade's talking points? I thought it was all about capacity now, not speed? Except I thought there were also rumblings about reducing capacity from the previous announcements? Hard to keep up...!
