Thanks for the link. That was a quick job. NR» (Network Rail - home page) must have been pleased that the OHLE▸ (Over-Head Line Equipment (electrification via catenary)) wasn't involved too.

More by luck than design, I suspect? I still wonder how many other unstable parapets they’d find if they did a serious search.  Will the majority of this viaduct, (the other bits that didn’t fail) have been re-assessed?   

I read somewhere that minor failures, (eg at Nine Elms), became much longer than the initial problem because the guardrails acted in such a way as to pull adjacent sections down, in a sort of domino effect. 
Maybe guardrails shouldn’t be continuous over such long lengths?
