I think what Nigel is saying Littlestone and Ishmael, is that if you rebore the old tunnels and take 10 inches off the walls then the route is still there but the old tunnels have gone and have been repalced by a larger bore.
And as I said further up, neither of you have been given the opportunity to read the reports and were not present at the discussions to witness the slant. Nigel is merely arguing for you and the wider public to have that right.
