BTW I see a bunch of people posting about this BBC piece about international rail in Europe and why it doesn't work better. It's fine explaining there is a problem, but has pretty much nothing on 1) why that problem really exists, and 2) what we can do about it. So it's not wrong, just not very new https://www.bbc.com/travel/article/20241101-why-is-european-train-travel-so-expensive #CrossBorderRail
