My first thought is the South Carolina Central yard at 621 Field Pond Rd, Darlington, SC 29540, but I am not sure the foliage is right...
The State of Confusion Museum? I am certain I know the State referenced. But am having no luck, so far. Haven't been there in over forty years, and everything has changed.
Ah. OK. I see Scott has the location. I have some difficulty picturing an old Gulf, Mobile & Ohio location as being CN these days.
Well done Scott You got the location. And Boxcab it is CN according to their route map. The engine there is in GT paint sceme.
