Kempton Steam Museum is home to the world’s largest working triple-expansion steam engine. It stands as high as four stacked double-decker buses and along with its identical twin, pumped vast volumes of London’s drinking water from 1929 to 1980.

The museum and its engines are housed within a grand Scheduled Monument located at the Thames Water’s Kempton Park Pumping Station in south-west London. The mighty steam engines have been preserved since 1995 by the Kempton Great Engines Trust to ensure that their engineering magnificence is treasured for generations to come.
