It's a bit different from driving locos or traction engines. To operate a large stationary steam boiler like the one at the mill you need to have a boiler operator's license, which requires in the UK under the BOAS scheme at least 6 months supervised experience running a boiler plus a training course plus passing the test. Steam boilers that size are extremely dangerous pieces of equipment with the potential to flatten an area the size of a city block if they explode. The WHS authorities and the insurance companies don't let any old untrained numpty run them.
In the past, to "drive" a stationary steam engine like the mill engine in question, you had to have what was termed an Engine Driver's License. Not sure what the status on those old piston engines is today. Today's licences are aimed at steam turbines and don't mention old piston engines.
I was just surprised the the job ad person specification made no mention of the boiler license requirement, which would seem to me to be the first prerequisite, having worked for some years running large boilers and steam plant. It is usually a very highly regulated workplace.
I certainly never would set foot in such mill if I knew the boiler operator was not trained. tested and licensed. Disaster waiting to happen.
