That said, it will become a far more critical bit of London's
transport infrastructure when it becomes part of the ELLX, so I guess
it's worth getting everything right first time round during this
closure and making sure all the works are done to a very high
standard.

But this isn't first time around! The ELL was closed for three years not
long ago, when conversion to third rail and use of NR rolling stock etc was
already inevitable.

Yes, I was aware of that though I didn't mention it. One would think
that any major remedial works were done then - the Thames Tunnel was
certainly 'dealt with', though the shotcrete treatment wasn't to the
liking of conservationists, which is of course why the line was closed
for so much longer than originally anticipated (and of course you know
this all already, but I'm just setting the scene for the audience!).

I'd be most interested in seeing a break-down of the works.

One other point to consider is what stock would be operating the line if
it reopened in 9 months (for example) time? Don't forget that the
conversion to National Rail standards with 3rd rail electrification
would rule out the use of A-stock

Oh, like how LU stock can't run to Richmond or Watford? I can't see why
there would be any problem putting in an earth-bonded fourth rail to
sustain the service until it becomes fully Overgrounded.

and there would be no connection back onto the LUL system for major
servicing anyway.

I hadn't realised that was happening. Is there a huge problem with doing
occasional stock transfers over NR lines? Apart from the fact that the
route would via Clapham Junction, some maneuvers out West, and the Dudden
Hill branch ...
