It’s August of 1940, and the United States involvement in World War II is still more than a year away. Jack Delano recorded this view of the Baltimore and Ohio Railroad facilities at Punxsutawney, Pennsylvania from a hillside overlooking the yard. That’s the Mahoning Creek Lake (actually a river) that the yard is wrapped around.
