I believe the fundamental difference between a U-Bahn and an S-Bahn is that
people who are unhappy with the U-Bahn should try to kick the mayor out of
the Rathaus, whereas people who are unhappy with the S-Bahn should try to
get rid of the Chancellor over in Bonn. This distinction doesn't really seem
to be the case with the Overground.

ITYM Berlin.

But the distinction *does* exist - the Overground is part of the
national rail network in both countries, including the fares system.
It just happens that the structure of said national rail system in the
UK is different to Germany.

Merseyrail is, I suppose, a similar example of an S-Bahn.
