This is the first I've heard of this. Anyone else know anything more about it?

It's hardly a secret. It's shown at

But where is the entrance that the link mentions? I must know!

That first article forgets that there was a platform on the loop, part of
Embankment station, from the opening of the loop. It's still in use. A
second Northern Line platform was added in 1926 when the Kennington
extension opened. The other map annotation doesn't distinguish between the
flooded and other sections.

The concrete plug in the tunnel was probably installed at the time of
Munich, when all the under-Thames tunnels were plugged. Later, flood gates
were installed in the tunnels still in railway use to allow services to
resume. Anyone know where the gate is in the southbound running tunnel? I
would expect it to be visible from the platform.

Are you suggesting that every railway under the Thames was shut
simultaneously for a while?

That's my understanding, yes. Detailed in chapter XIII, The Second World
War, pages 127-8, of "The story of London's Underground", by London
Transport, first published 1963, revised and enlarged to 1972 in my copy.

What about the ELL tunnel at Wapping? Does that have flood doors?

I'm not sure it does but then the potential effect of a breach of the
under-river tunnel might have been regarded as less.

From my memory of a couple of tours under the Thames I don't remember
seeing such doors.

Was the ELL in use in WW2? A flood in those tunnels would wipe out a few
stations either side at least.
