Sanding the flues does look like this, however. There seem to be some people standing by the track. Photo runby maybe? Sanding the flues enroute occasionally would seem to make for better conductivity between the exhaust gas and the surfaces of the fire tubes and the boiler water. All that carbon buildup could be a pretty good insulator. How would "bad fuel" be the answer. Weren't they just using regular diesel? Just a couple of guesses.
