London Reconnections are reportingthat the Jubillee Line upgrade (whic was originally due to be completed in March 2009, then December 2009) will not now be complete until mid-October 2010 (at the earliest), although the Evening Standard expect this date to be missed.

Obviously, had the upgrade been completed as originally scheduled, we would be able to use the extra 30% capacity to travel east from Canada Water. I suspect that most who work in Canary Wharf will continue travelling via LB in the morning and return using the ELL.
