In Aug 2016 platforms 1-3 close and trains to Cannon Street cannot stop at London Bridge.
Southeastern have released their draft timetable which can be seen here http://www.southeasternrailway.co.uk/your-journey/timetables/august-2016/
It looks like some Greenwich line trains are diverted via Lewisham so other Dartford lines have less stopping there.
Some trains on the Greenwich line also start further back at Medway towns, at the expense of Sidcup line, apparently to provide more links to crossrail at Abbey Wood. The timetable ends before Crossrail is supposed to open however?
