Train journeys will be disrupted later this week due to major engineering work between Clapham Junction and Weybridge.
All routes to and from London Waterloo will be affected, with changes to train timetables from April 6 to 9.
A replacement bus service will run between Clapham Junction and Chessington South, to replace the train service running from Waterloo.
Journeys between Waterloo and Basingstoke will also be diverted through Clapham Junction, with a reduced service running between London Waterloo and Twickenham to accommodate trains.
