Rail passengers in Surrey and southern England are being urged to plan ahead due to upcoming line closures for upgrade works.
From 25 October to 2 November, services between Staines and Windsor, and between Guildford and Havant, will be suspended and replacement buses will be running.
The closures coincide with the school half-term, a period Network Rail says typically sees fewer passengers.
Mark Goodall, Wessex Route Director for Network Rail and South Western Railway, said: “We’re very sorry for the disruption to journeys at the end of October.”
