Major railway upgrades are set to take place during the October half-term between Wokingham and Reading, and Staines and Windsor.
Network Rail will carry out significant track renewal work, resulting in bus replacement services from Saturday, October 25, to Friday, October 31.
On the Wokingham to Reading line, buses will replace trains for three days, from Saturday, October 25, to Monday, October 27.
Engineers will replace the Reading Spur Junction during this closure, which links the Great Western Main Line and the North Downs Line.
South Western Railway services to and from London Waterloo will start and finish at Wokingham during the works, as will Great Western Railway services to Gatwick Airport.
Mark Goodall, Wessex route director, said: “It’s important to stress that most of the South Western Railway network in Berkshire and North Surrey is fully open throughout the October half-term but we’re very sorry for the disruption to journeys in the Reading and Windsor areas during this period.
“We know there’s never a convenient time to close the railway, however passenger numbers are typically lower during the half-term week, making it the least disruptive time to carry out this critical work.
“Our teams will be working around the clock to deliver these upgrades, and once complete, passengers will benefit from smoother, more reliable journeys.”
On the Staines to Windsor & Eton Riverside line, buses will replace trains for the full seven days during the half-term closure.
The works will include more than a kilometre of track replacement at Wraysbury, road and drainage improvements at Datchet Level Crossing, and extensive repairs to Colne River Bridge and Black Potts Viaduct.
Two buses per hour will operate between Staines and Windsor, stopping at all intermediate stations.
Alex Hills, GWR station manager at Reading, said: “This improvement work supports our commitment to improve rail services for Gatwick, supporting the airport and sustainable travel choices.
“During this three-day period, GWR trains will operate to an amended timetable – running between Wokingham and Redhill or Gatwick Airport.”
Passengers are advised to check their journeys in advance on the National Rail website or through their train operator.
