What follows in an email from Southeastern:
The London 2012 Olympic and Paralympic Games begin tomorrow, and with it our timetable changes. You can collect a Southeastern 2012 Games pocket timetable from any of our stations or download them from southeasternrailway.co.uk/olympics.
Our services will be very busy throughout Games-time and you should expect to queue for trains at many of the busier stations we serve e.g. London Bridge and St Pancras International. Queuing is expected at all London termini and venue stations from Saturday 28 July, please allow additional time for your journey.
On the evening of Monday the 30 July you will not be able to access platforms 1-6 at London Bridge station from 6pm to 10pm, please use Charing Cross, Cannon Street or Waterloo East instead.
A one-way system and a queuing system will be in operation at London Bridge station throughout the Games, as well as restricted entry and exit points to prevent platform overcrowding. Passengers are advised to avoid using London Bridge wherever possible, in particular avoid trying to change trains or access the Underground. You can find more detail about this at southeasternrailway.co.uk/olympics.
If avoiding London Bridge is not possible, passengers are advised to exit the station and complete their journey on foot. For walking information from your station please visit the TfL Journey Planner.
Dont chance it over the first few days of the Games, plan ahead now and allow extra time for your journey.
