Yeah, as a piece of knowledge, and what I've been saying is it's European thing.
I can hop onto Tokaido Main southbound at Tokyo with $1 ticket and get off at same Tokaido Main platform at Kyoto, or vice versa, or same for Ueno to snowy Aomori through Tohoku Main, if I didn't mind paying $60 outstanding fee and a 12-hour 5 train change long "metro" experience and "oh come on" look at the gate. By all definitions the Tokaido or Tohoku line are a "metro" rail, and uses some of same models of rolling stocks(cars) as literal subway services. I can technically do that because there's no hard distinctions between metro and train in the system I'm familiar with but the rails are rails and rails go everywhere.
European cities tend not to have that, and instead have often Y shaped branches off international long-distance rail networks that comes in and backs out of a "City Central" station, where it connects to local train services like trams and subways. This is due to Europe long having concept of city boundaries where city-ness of cities roll off sharp and somewhat abruptly ends, and many cities have not expanded enough to fuse together like late-game Civ maps.
Yes, I am aware, what I'm saying is that not everyone knows and you have to say it. You can't say, like, the author's stupid to not be aware of obvious distinction.
