Well ... I ran my mixed freight local with the 0-8-0 at the head end. Ran her wide open for several dozen laps around the layout, and she started to puff and put out some more smoke, but not a whole lot. On a scale of 1-10 ( with 10 being a boatload of smoke ) I would say it was at 3 at best.
Is this the best to expect from this locomotive ?
