The Hampton & Kempton Waterworks Railway (HKWR) is the only operating narrow-gauge steam railway inside the M25. Open every Sunday from March to November, you can ride in beautifully-restored Devon coaches through the unique location inside the Hampton & Kempton Waterworks – hauled by 1915 steam locomotive Darent.
The railway played a key part in cleaning London’s water supply in the late 19th century, and still sits alongside the world’s largest steam water pumping engine at the Kempton Steam Museum.
