Overground tube system?

* Overall this is good news for people in Forest Hill and Sydenham who

finally get to join the tube system.

The overground as 'part of the tube system' seems to be a fairly regular
mistaken belief. *Only last week I read about an MP (Battersea?) who was
looking forward to ELLX phase 2, so that Clapham junction could finally be
part of the tube network...

I don't see a problem with that. London Overground is on the tube map,
and the service along their lines is supposed to go up as well. I
don't see how these lines are less of a 'tube' line than an Amersham
to Baker Street service, for example. People also call the DLR a tube
line all the time.
