LU wants to learn lessons from London 2012

London Underground boss Mike Brown describes the Olympics as a "live laboratory experiment" for Tube managers.

He also said that for the first time in Tube history "we were able to change the behaviour of some of our passengers".

LU has now appointed a senior official to devise a plan to learn lessons from the Games. Mr Brown says the Victoria Line upgrade will be complete by the start of the New Year. But the District Line upgrade will not be finished until 2012.
