There will be no trains at London Cannon Street this weekend because of engineering works.
Southeastern has warned passengers to use alternative routes because of engineering work that needs to be carried out near London Bridge.
Routes between Cannon Street and Hayes, Barnehurst, Slade Green, Orpington and Dartford will all be affected by the closure.
Southeastern said: "Although the Platforms at London Bridge are finished Network Rail still require time to finish some work on and around the tracks in the London Bridge area. As such this weekend 24 and 25 February there will be no trains to London Cannon Street and platforms 1-3 at London Bridge."
Lines will be closed because of the work which will be taking place near Cannon Street and New Cross, closing lines.
Trains will be replaced by buses between New Cross and Charlton, via Greenwich.
