Network Rail will close parts of London Bridge for 16 days from December 20, as two new platforms are brought into use and 40-year-old track and signals are replaced at the approach to the station.
The work is part of the £6.5 billion Thameslink scheme, and up to 750,000 journeys will be affected. NR says this period has been chosen because commuter journeys usually drop 10%.
In January, Platforms 5 and 6, which are currently used by Thameslink trains, and those serving Charing Cross will be taken out of use.
