@tml @olynch @albertcardona @elduvelle I think it's pretty easy to tell by the fact that it is not a major plot point in books and movies of the 20th century that it is impossible to get from one point to another without several missed trains, replacement busses that don't show up, etc. In those days, people made plans that required them to arrive at a certain time, and those plans generally worked.
The 20th Century would have been impossible without functional rail transit. Today, plans that involve travelling by train must necessarily involve arriving a day early and paying for a hotel if you need to guarantee an on-time arrival.
