The US famously bulldozes whole districts for their stupid highways, to build a whole highway junction inside cities (or whatever is left inbetween highway and parking lot).

Sure both train tracks and highways are harder than flock cameras or data centers, but the US certainly has no issue with building highways. All the issues are home-made. We have the same fucking issues here in Germany, it just so happened that more of our rail network (relative to size & population) survived the neolibertarian onslaught of the past ~60 years.

At the end of the day train networks primarily serve people, not capital.
