Planned engineering work
We need to do engineering work to maintain and improve the rail network. Much of this work is done at weekends and during holiday periods, but some work also needs to be done overnight during the week.
Buses will replace train services where lines are closed for work to take place. We may also have to alter train services over a wider area.
Please use the Engineering Work calendar and click on a date to get information about planned engineering work for that day.
For the latest information on how London Underground services are running, we recommend you visit the "Transport for London" website.
Late alterations to planned work in July
Additional work has now been planned for Sunday 27 July .
Between Clapham Junction and Barnes - buses replace trains all day. Trains to and from Reading and Windsor & Eton Riverside will be diverted and other local train services altered.
Between Haslemere and Havant - buses replace trains all day.
To complete this work, buses will also replace trains between Haslemere and Havant late evening from Monday 28 to Thursday 31 July.
