It was an example of a station with surface-level platforms so far
above sea level that that being on the "Underground" is arguably
more bizarre than Brighton being similarly branded.

In Hamburg, there is a section (Roedingsmarkt-Rathaus, roughly) where
the U-bahn is elevated about 5m above the ground, and the S-Bahn is
underground...

AFIAK, U-bahns are controlled by the city government and S-bahns are
controlled by the federal government, and there is no particular reason why
an entire U-line couldn't be overground or an entire S-line be underground,
although the latter is particularly unlikely.

At Stratford station the Overground platforms are downstairs from the
Underground platforms.

Willesden Junction has Overground and Underground on the same tracks. Er,
with more Overground on top of them ...

What does the NLL do at Stratford now? That used to have the Underground,
in the form of the Central line, on top of the Overground (although it
wasn't called that at the time!); then they added another bit of
Underground at the lower level (the Jubilee), and have now possibly
rerouted the Overground to the higher level. And of course there's
overground-with-a-small-o at the higher level, and at some point there'll
be DLR at both or something, i don't know. No plans to add yet another
underground line on top of the existing high level platforms that i know
of, sadly!
