Olympic travel in London
Monkeyboy sent us a link to Getaheadofthegames - a website dedicated to providing Olympics-focused travel information. The interactive map of London allows you to see the likely hotspot stations on a day-by-day basis, depending on what events are taking place at the Olympic venues.
Not surprisingly, London Bridge and Canada Water are both expected to be "exceptionally busy" during both morning and evening rush hours more often than not (10 and 9 days out of the two-week period respectively). Data for the Paralympic Games is not yet available. The site also note that rail and tube services will run later than usual and that night services on the Jubilee will be more frequent.
