The two 'Great Engines' were the heart of the water treatment works at Kempton Park in Middlesex, supplying North London with drinking water taken from the Thames. The magnificent building in which they are housed is a national monument.
The engines date from 1926-1929 and are thought to be the biggest ever built in the UK. Each engine stands 62 ft tall from the basement to the top of the valve casings and weighs over 800 tons. They were supplied with steam by a battery of coal fired water-tube boilers.
One of the two engines has been restored to full working condition and can be seen in steam on selected open weekends throughout the year. Guided tours are available over the other engine at other times.
