I rode the CIR line from the interchange with the BNSF at Sangamon and 16th, all the way down Cermak and Blue Island, to the overpass at Western Avenue. All the Tracks Along this route were lightly overgrown, and looked like they had not been used for at least a year. The Switches at Kramer, Sims, and Battaglia had all been removed. The track that loops down to Domino Foods looked heavily used, and there were at least four covered hoppers down by the river. There is also an in-use siding that services LPI Distribution coming off this track. I talked to an employee at Kramer and he said there had not been any trains servicing there for a long time.
