The essential engineering work will take place over the February half-term, with trains replaced by buses on key routes and timetable changes across parts of the network.
The main closure will run for nine days, from Saturday, February 14 to Sunday, February 22.

Train services into London will continue to run via the Sidcup, Bexleyheath and Woolwich lines, although passengers should expect timetable changes.
