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

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.

"In 1939 there was concern that bomb damage could flood the under-river
tunnel, after which the water would rise through the shaft at
Rotherhithe station and flood the surrounding low-level ground.
Therefore a double floodgate was installed at the north end of the
station."

Interesting page.

"The line closed as an Underground line in late 2007 and was integrated into
the London Overground network as "route 4". It remains owned by London
Underground, though the signalling is maintained and operated by NR. "

Is that still the case? I thought the whole ELL that doesn't run on southern
lines is owned and run by TfL including the signalling.

No, it's owned by TfL but Network Rail does the signalling. It's
signalled to NR standards (including PoSA aspects), not LU.

Also, the section parallel to the NLL is owned by Network Rail, as I
understand things.
