Well the TfL press release at

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?

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.
