Full Description

Kempton's magnificent 1927 engine house houses a pair of 1,000-ton triple-expansion steam pumping engines, one of which is now the largest working example in the world. Restored by volunteers over a 10-year period, it now steams one weekend a month from March-June and from Sept-Nov. Also on site are two steam turbines and a rare working mercury arc rectifier. The building has been preserved as a heritage site, exactly as it was when it pumped millions of gallons of water a day to North London until it closed in 1980. The narrow-gauge railway operates every Sunday except December, plus steaming weekends. Special events include car shows, model railway exhibitions and much more. Guided tours always available plus a Guest Driver Experience for anyone wanting to have a go a running the Triple. Refreshments include home-made cakes and savouries.
