This is what railfanning CBNS is all about - those green ex-DEVCO coal
hoppers, that make up a large portion of car traffic. I would of shot a
similar photo with the CN ore cars had I not been focussing on their rosters
instead, since they're pretty rare. In school I was taught not to combine
various shades of the same color do to poor visual effect. Is this enough
greenery for you?
