Just to the left of the hopper is the junction point between the C&E and Deering Lines. My guess is that a crew is working the Deering Line at this moment and left the rest of the train on the start of the C&E Line.
Note how Kingsbury Street was paved in dirt in 1980. That’s Finkl Steel to the left with one of its two spurs entering the property. This spur is still visible inside their fence in 2010 though no longer connected to the outside world since it was sliced off in 1985. This view looks northwest from about Cortland Avenue. In 1985 the City of Chicago would repave this section of Kingsbury and new trackage would set in concrete in the middle of the street with asphalt around the sides.
