Running the 1912 blast injection Diesel engine at Internal Fire in Wales. One of the oldest working Diesel engines in the world, built to Dr Rudolph Diesel's original design.
One of these 300hp diesels running drainage pumps is about to be removed for display at the museum.

Six cylinder Ruston genset, first public run at the museum at the 2007 End Of Season event. Not installed yet and just running on temporary air and water connections.
Turning over on air for the first time in 25 years. This was a test to check the timing and air start vales and is being done using a small bore hose - as a result she is only just turning over
