Not too often you see barns that have a walkway between them, but I found these two did as a loaded coal train rolls east on the Ottumwa Sub about 30 miles west of Burlington, IA, near New London. This train is running 2x1 DP setup with 133 cars from Converse Jct., WY (Antelope Mine) to Monroe, MI (Detroit Edison Monroe plant) via NS Chicago, IL.
