Another problem would be getting the smoke to exit the chimney in an authentic manner.
On the full size version the smoke from the fire is dragged through the boiler tubes by the action of the cylinders exhausting through the blastpipe. If the model wasn't " live" you would need a variable speed smoke generator to mimic the actions of the full size version.

Cheers John
