Network Rail has released this timelapse video of works that took place at London Bridge station over the bank holiday weekend.
Part of the busy station was closed from Saturday 23 May to the early hours of Tuesday 26 May to allow major improvement work.
The rebuilding of London Bridge station and the tracks around it forms a key part of the £6.5bn Thameslink Programme.
A Network Rail spokesman said: “This was another vital and busy weekend for us and we appreciate passengers’ patience in bearing with us while we do the work.
“Regular commuters will see that the former platforms 5 and 6 have been demolished, leaving room for the station construction team to move in and crack on, and the track has been dug up and repositioned, giving Charing Cross trains a different path through the station.
“In addition, this weekend a bridge carrying trains over Joiner Street - better known as the pedestrian entrance to the station from Tooley Street - has been jacked up and set down on new supports, increasing the strength of the bridge to cope with increasing numbers of trains.”
