This is the polar opposite of Europe. I've taken even the run down ugly german trains that they still run on irregular routes and even though the trains are antiquated, they make sense and get the job done. People are respectful even if the train is packed. I wouldn't want to go back to trains in America other than for sparse occasional trips.
I often look at maps like this and think maybe that would be amazing: https://i.imgur.com/srMhE1X.png
But then i'd probably just take an airplane for most trips because 1-2 hrs of leg cramps with a typically quiet passenger crew is better then a misbehaved train carriage.
Fixing the trains is not fixing the society. The trains are probably broken because the society is broken.
