IMPORTANT NOTICE ABOUT THE STEAMING OF THE ENGINES.
Unfortunately the site steam boiler has accumulated a number of too-expensive-to-solve problems and so was permanently taken out of service in 2021. Therefore, for the foreseeable future, the museum will have no steam.
Alternative means of driving engines are now as follows -
The Goddard & Massey beam engine is running by vacuum, effectively as an atmospheric engine.
An electric-motor-driven blower delivering air through the former steam supply pipework, at 500 millibar, 7 pounds per square inch. The low pressure air system can operate seven engines, plus two others, for a short period on request.
There are four engines driven by electric motors:
“Reliant”, J Samuel White compound, Sisson triple expansion, and Burton test engine
Museum development work is continuing. April 2023.
