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. It has been restored by volunteers over a 10 year period. 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.
