Kooklik,
Challenger 4-6-6-4 #3985 has been converted from being coal fired to being Bunker C Fuel Oil fired. This was done to prevent against coal cinder caused forest and prairie fires.
Not sure how this might affect authentic weathering of the Big Boy, but I would think that the way she now weathers it would present a more "oily" than a "dusty" appearance as it would with coal.
