Aerial chrome of the Elkhart, Indiana railroad hump yard — one of the largest and most technically advanced classification yards in the world at the time, filling the entire frame with dozens of parallel tracks fanning out from the sorting ramp, hundreds of freight cars in every stage of classification, flat Indiana farmland stretching to the horizon. Elkhart was the nerve center of the New York Central Railroad's midwest operations; the electronic hump yard, where cars were automatically weighed and switched to one of 72 classification tracks without human intervention, was considered a marvel of postwar railroad engineering. Someone who studied this card added a handwritten note with arrows pointing to specific sections of the yard: "Pig Dis is Indiana" — shorthand for Piggyback Dispatch, the trailer-on-flatcar service that was revolutionizing freight movement in the early 1960s.
