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 and there would be no connection
back onto the LUL system for major servicing anyway. The new Class 378
units for the line will only start arriving towards the end of 2008
for service in 2009 and I understand that it is the dual voltage units
for the North London Line that will be first in service, with the DC
only units following. For these to run on the ELL, the depot will need
to be ready as well, as there will initially be no connection at
Dalston between the North and East London Lines.- Hide quoted text -

They could have started the closure later, though! (w.r.t stock I mean
- I don't know enough to comment on the engineering/conversion issues)
