Less well advertised than the changes from 12th January 2015 to London Bridge is that there are NO TRAINS via London Bridge platforms 1-6 on the weekend of 10th-11th January 2015:
From 01:10, Saturday 10 January 2015 to 04:00, Monday 12 January 2015., there are no train services calling at (in alphabetical order) DEPTFORD, GREENWICH, LONDON BRIDGE (platforms 1 to 6), LONDON CANNON STREET, LONDON CHARING CROSS, LONDON WATERLOO EAST, MAZE HILL OR WESTCOMBE PARK.
The Gillingham – Charing X semi-fasts via Woolwich Arsenal are diverting fast to Victoria after Lewisham
The Dartford – Cannon St stoppers via Woolwich Arsenal divert at Charlton via Blackheath and Lewisham then fast to Blackfriars
The Gravesend – Charing X via Sidcup services will terminate at New Cross, calling additionally at St Johns and Lewisham
It looks like the Dartford – Charing X via Bexleyheath services are cancelled, leaving the scheduled Victoria via Bexleyheath service.
