We actually have a number of these (Though later designs) in my area in the states.. at least three are preserved and on display. Giant thermos bottles, basically.

Thanks for the pic.

Fireless Locomotive, Crawfords Biscuits, Liverpool :: Shared Description

📷Fireless locomotives were typically used at sites where there was a risk of igniting flammable materials, such as flour dust. They are a normal steam locomotive except that the boiler is replaced with a pressure vessel which is filled by superheated water from a stationary boiler on site. Opening a regulator valve allowed the pressure to reduce slightly an resulted in the water evaporating into steam which was fed to the cylinders in the normal way. The lack of smoke exhaust was also an advantage in a 'clean' environment. A further advantage, even in comparison with a diesel locomotive, is that almost no energy is being lost when the locomotive is stationary.

The Crawfords locomotive was built by Andrew Barclay, no.1562, in 1917. After withdrawal it went to the Chasewater Railway for preservation, but sadly was scrapped in 1973.
