I have never ridden Amtrak in the United States, VIA Rail in Canada or fancy luxury trains in the Middle East or Japan but I have been on passenger trains in Spain, Czechia and Slovakia because they are going to places I want to visit. It was super convenient to get from city to city and town to town but something like this in the United States and Canada is practically non-existent. Mexico is very well connected with big luxury buses from city-to-city and smaller old-fashioned colectivo buses from town-to-town. The Tren Maya opened recently in Mexico but then shut down again due to so many logistical problems.
