South Western Railway (SWR) is advising customers of engineering work in London affecting services on Saturday 15 and Sunday 16 March.

Network Rail engineers will carry out vital maintenance on a set of points – moveable sections of rail that allow trains to change from one track to another – at a busy junction between Queenstown Road (Battersea) and Clapham Junction.

Train services that run between London Waterloo and Barnes, Kingston, Reading, Richmond, Twickenham and Windsor & Eton Riverside, and some services via Surbiton, will be affected.

On Sunday ,16 March, buses will replace trains between Clapham Junction and Twickenham via Richmond, and between Kew Bridge and Clapham Junction.

Afternoon and evening services between London Waterloo and Kingston via Hounslow will not run on this day.

Customers are advised to plan ahead using a journey planner which can be found here.

Peter Williams, SWR's customer and commercial director, said: "On the weekend of Saturday 15 and Sunday 16 March there will be many changes to train services.

"Rail replacement bus services will run, and some journeys may take longer than usual, so it's important that customers plan ahead.

"For more information we recommend checking our website. We are very sorry for the disruption that this will cause, however, customers can expect a more reliable railway when this engineering work is complete."

Mark Goodall, Network Rail's Wessex route director, said: "We know that closing the lines in and out of London Waterloo station will be disruptive to passengers and we're sorry to anyone who will be impacted by this work.

"The junction between Queenstown Road (Battersea) and Clapham Junction is extremely busy and needs renewing to keep trains running safely and reliably.

"We urge passengers to plan ahead and check before they travel and thank them for their patience while we carry out this vital work."
