At Canning Town, I descended by stairs from the Bus Station to the

replaced. I was confused by a notice saying escalator replacement takes
6 weeks and the replacement would end in July 2008. A CSA explained July
2008 was the date for the escalator system replacement program to end.
Does anybody here know the story? ISTR that line was opened in 2000 for
the Millennium. What is the design life of an LU escalator.

Opened in 1999. Are you sure it's 'replaced' rather than
'refurbished'? It wouldn't surprise me especially if the escalators
need 6 weeks of heavy maintenance after nearly 10 years' service, and
6 weeks sounds definitely more like a 'maintenance' than a
'replacement' timescale (iirc it's at least 3 months to install a
wholly new escalator into an existing shaft).
