Chicago North Shore & Milwaukee 727. This one follows the previous photo about 12 miles down the road.
Iowa county road B-35 parallels the railroad. Makes photos easy, especially as the road is on the south side of the RR.
From Emery to Mason City, the trolley poles are along the north side of the tracks, but from Emery to Clear Lake, they are on the south side.
So, when you shoot, you must pace your shot to be between poles. Now if Dave would only move them to the north side.
