Gordg3:
The isolated section of spur track into Finkl Steel is on the west side of Kingsbury, opposite from Magnolia Avenue, just inside the Finkl complex. It is normally behind a closed gate and not easily visible from the sidewalk. Your picture was probably taken when the gate was open so it might be tougher to spot it with the gate closed. You can see the track between openings in the fence and gate however from the sidewalk.
