In theory, London 2012 is meant to be the "public transport games".
There is of course a wide gap between aspirations and reality. London's transport infrastructure suffers from a lack of investment and capacity. Hence the services are inadequate and overcrowded.
Transport for London (TfL) are aware of many of the problems, eg they have warned that it may take an hour to get on a train at St Pancras station (where the Javelin train will depart for Stratford).
They are mounting a campaign to ask people to commute less (they need a 30% fall in commuter numbers)!
Sadly it seems that the word "obsolete" applies not only to the infrastructure and capital equipment, but also to the thinking within TfL.
