Very near Cambridge (about 18 miles) is the Fenland drainage museum at Prickwillow (two old diesels I believe), and also ,even nearer (about 12 miles ) a steam drainage engine at Stretham. Also a little bit further away on the A10 at Brandon Creek is a Very large Crossley fenland drainage engine. This as far as I know is not open to the public but can be viewed through the windows from the adjacent river bank.
My Uncle ran this and a very large Mirrlees (now dismantled and gone) on this site for many years. If you knock on the door of the adjacent house, which he and his family lived in) the owner might let you into the engine shed for a look round. The surviving Crossley is about a mile north of the river bridge at Brandon Creek on the A10 ,on the left as you head North. On the right is a modern brick building housing the replacement automatic electric pump. You'll see the big engine shed and can probably park in the yard to get access to the river bank (about 40 yards.)
I believe the Stretham and Prickwillow engines have running days but you'll have to check all this on the internet.
