That was either the best joke ever, or you haven't used German S-Bahn yet. (The "S" is supposed to be short for the German word for "city" but we jokingly refer to them as "standing still-train" instead of "city-train")
'Stand-Bahn'? Never heard that, although haven't lived in Berlin since before the 'meltdown' in 2008. Traditionally the S-Bahn is Berlin's favorite transit system (you can look out the window!), the most far-reaching, and the most interesting historically.
Actually I don't think it is 100% known what the "S" stands for. I think "Stadtschnellbahn" is most likely. The "Stadtbahn" only refers to the east-west route.
You should travel more. You would never complain again. Berlin public transport is amazingly consistent compared to anywhere else I have lived (bar Singapore).
even if they're running late it should be fairly accurate; there are no express trains here in Berlin so it's never very long since a train has been in a station for a positional fix.
