I bought two Railking Baltimore & Ohio SD9's from the 2002 MTH catalog a short while after they came out. I've always enjoyed them but after 15+ years of looking at the same paint scheme I decided it was time for a face lift. The prior paint scheme while prototypical was not one of my favorites. I always liked the later blue dip with the big old "B & O" on its side. So that's what I did.
Old scheme
Fresh blue paint
One down, one to go.
