We have broken down the details for you to plan ahead.
Staines to Windsor
The lines between Staines and Windsor will be closed.
London Waterloo to Windsor services will be diverted after Staines and terminate at Ascot.
Buses will run between Staines and Windsor.
Haslemere area
The lines in the Haslemere area will be closed due to maintenance work.
London Waterloo to Portsmouth via Guildford services will terminate at Guildford.
Rail replacement services will run between Guildford and Havant.
These services will not call at Farncombe; a shuttle service will operate between Farncombe and Guildford.
Customers at Farncombe wishing to travel towards Haslemere and Havant will need to use the shuttle service to Guildford and then use a separate rail replacement service.
A statement on the South Western Railway website says: “Late evening and early morning services may need to be altered for emergency repairs or planned work.
“We are sorry that bulky luggage, cycles and prams cannot be carried on the replacement bus services.
“Please check if you are planning to travel after 11pm or before 5.30am as buses may replace trains at short notice.”
