One morning I visited the Kew pumping station museum, where a fair number of stationary engines are displayed. Unfortunately the staff on duty know almost nothing about steam engines, as the experts come on certain days when the engines can run. Their boiler recently failed inspection, so no steaming until that is resolved. There are two enormous beam engines in the pumping hall. Their cylinder diameters are 90 and 100". I calculate the 100" piston at 40 psi would see 157 tons of force! One can climb the steps to the top of the engines to see the cylinder heads and beams up close.
I just returned from a trip that included 4 nights in London. One morning I visited the Kew pumping station museum, where a fair number of stationary engines are displayed.

The displays are not very good as each model has its own glass case and then 11 of these are in two large cases, also glassed. In one of these the lights weren't working. I have the picture book on these engines, but seeing them up close was still impressive. There are 13 engines in total there.
Any London visit should also include the Science Museum.
