It’s nearly time to power up the Sir William Prescott Engine and we hope you’ll join us on Saturday October 17th and Sunday October 18th to revel in living, breathing engineering history!
Almost 100 years old, the Sir William Prescott Engine at Kempton Steam Museum is the world’s largest working triple expansion steam engine, once pumping 19 million gallons of London’s drinking water every day.
Book a guided tour of the engine's twin, the Lady Bessie Prescott Engine, currently being lovingly restored by Kempton’s team of wonderful volunteer engineers.
Located with the Kempton Park Waterworks in southwest London, you’ll find us just off the A316. There’s plenty of parking, tea, cake and 800 tonnes of precision engineering in action.
