I like noticing the small differences when I visit different countries. In Brussels, I noticed the ticket machines with a dial to turn to select your ticket and the escalators that don't start moving until you get on them.
I stood at a station, waiting for a metro, and there was music playing, and that made me feel somehow like I was in a movie.
Brussels has a pre-metro, as well as a metro, and these are actually trams that may go underground. I thought I had got on the metro, but later found it was actually a tram (pre-metro).
