The problem here is that Europe optimized for passenger rail (so the rail is fast, which is good for people, but expensive per mile, which is bad for freight) and the US optimized for freight with the reverse positives and negatives.

The only country that I’m aware of that did both great on the same network was China, but they ran into capacity issues so they spent hundreds of billions to move people onto a brand new dedicated passenger high speed rail network and now the legacy slow one has more room for freight.
