There is also the Crofton Beam Engines on the Kennet and Avon canal. The 1812 engine there is the oldest working steam engine in the world. The Birmingham museum claim that their engine from, I think, Ocker Hill, is the oldest, but it justs goes up and down - it doesn't actually work, while Crofton pumps water. When Crofton is in steam, the Waterways people shut off the electric pumps, so it really does work! The other engine there is a new one - 1846. Can't remember how much it shifts each stroke - I ueed to know. It takes about 25 minutes to shift enough water to fill a lock - about 65000 gallons. Several of the people who started the Kew collection came from Crofton, funnily enough. Crofton is also in very nice countryside - I had my wedding reception there.
