@notes @ArrowbearMoore I read a lot about trains in both continents.
The History is the same on both sides of the Atlantic: pro-cars policies started in the 1920s and are still very strong everywhere. The only change is petrol-crisis related: Europe is not built over an oil field, hence investments in public transports since the 1970s.
For long runs, geography is responsible for the lack of long distance trains in NA: planes took over trains, even for short distances.
