Heritage Open Day: Come and see the 'award winning' 1861 Easton Amos land drainage machine in action and take a train ride on our 2' narrow gauge railway. Steam-powered land drainage on the Somerset Levels began at Westonzoyland in 1830, with the first of eight pumping stations built on the banks of the River Parrett. See the award-winning 1861 Easton Amos land drainage machine in action, and other engines, winches, turbines and pumps using steam raised by our 1938 Marshall Portable Boiler. We have one of England’s largest collections of working steam engines and pumps. The Museum also features a 2-foot narrow-gauge railway for demonstrations and passenger rides, along with a rolling stock shed to explore.
