> Not as bad as the Glasgow one, which feels like travelling on a 2/3 scale model of a subway with alarmingly narrow platforms.

For anyone who's not aware, the Glasgow Subway is literally smaller - the track gauge is 4ft (85% of standard gauge), and the rolling stock (trains) is similarly scaled down, to the point that you probably have to duck if you're over 6ft.

I remember that one of Stockholm's train line is also endearingly tiny too?

Budapest subway is something similar, too.
