Can somebody tell me why in the USA and Canada there have never been used "Classes" on the passenger trains like in Europe?
Europe has/had first class/second class/third class and even fourth class coaches, sleepers and sometimes even diners. And always the class number was visible, usually near the doors.
Why US and Canadian trains never had this? Why are coaches in in North America considered 2nd class and sleepers 1st class?
What´s the reason behind that totally different use of classes in railroading between the 2 continents?
