Here's the caption they added:
"We are back in Chicago and once again at Clybourn station, the first station to the north and northwest of downtown Chicago. This Stecher (C&NW employee) photo was probably taken about 1917. Straight ahead of us is today's Metra North line while the today's Metra Northwest line veers away from the station just past the station. The building on the far right of the photo still stands and was originally, as you can see, a pickle plant which took cucumbers from a lot of farmers along the north and northwest lines."
