Smallbrook Junction is similar to Friedrichstrasse, BTW, when Berlin
was divided; It was not possible to leave the station if transferring
from the U-Bahn to the S-Bahn, IIRC. Similarly at Smallbrook Junction,
you can only transfer between the Island Line and the IoW Steam
Railway and vice-versa -- there is no exit at all from the station.

Are there many other stations like that in Europe, or the world for
that matter?

Among the small number that used to exist was Killin Junction, where you
could change between the Caledonian Railway Oban line and the Killin
Railway

(old enough to have changed at Killin Junction)

You could leave the station, though, according to Wikipedia. That is not
possible at Smallbrook Junction.
