Good catch on the C&NW train approaching Oakton Avenue on the C&NW Valley Subdivision. Behind the train was Farley Candy which was also a rail-served customer at this late date. Farley, like this train line, is long gone now.
For others on this forum who are not aware, there's an active Yahoo Group that focuses on the C&NW (and North Shore Line) lines in and around Skokie, including the Valley and Mayfair Subdivisions which are both gone now.
