I hear that the H&C could be 2 months before it is back in order (worst
case because they don't know the tunnel status until the police vacate
site and Piccadily is anything up to 8 months if the tunnel needs a
rebuild - comments?

Well the TfL press release at
http://www.tfl.gov.uk/tfl/press-cent...t.asp?prID=428
says they expect to have a full service running on the Circle/H&C five days
after the police have finished their investigations. I don't think they
would say that unless they were confident there had been no major structural
damage.

If the reports today (that the explosive was mostly Acetone Peroxide) are
correct, then it would be unlikely given the damage to the train that
any serious damage was done to the tunnel.

Since the rest of us aren't the explosive experts that you are, David,
perhaps you can explain that remark?

That explains the chemistry, but says little about what type of damage
it might cause, and why. There were some early reports that the type of
explosive could be guessed from the way that victims' clothes were
"blown off" and other contemporary descriptions of the sound and light
accompanying the blasts. Perhaps these are what were being referred to?

I suspect he means what I've already thought, i.e. that the damage to
the heavier parts of the subsurface trains is fairly limited, menaing
that the blast furthur out would have been sufficient to significantly
damage the tunnel.

It's difficult to make a really large bomb with Acetone peroxide
because it is so unstable. Having a professional chemist may mean
that the reaction product has been stabilised by mixing with other
similar but less friction-sensitive chemicals, but it's still not
a compound to trust.

Investigations have shown no structural damage to either Circle/H&S
roof/sidewalls. There is supeficial damage to cabling and the immediate
areas but this will not take too long to fix. The Picc is a different
story. However its possible the Vic line will be resume stopping at
Kings Cross later today. This will allow interchange with Met and
mainline/Thameslink. Northern still being assesed.
Just when i was starting to enjoy the summer walk from Euston.....

No sign of the Picc/Northern/Victoria ticket office outside the mainline
station re-opening when I got the 15:45 to Cambridge this afternoon.
