Coincidently there is a running discussion on the Yahoo group about this line to the ComEd facility right now on the North Shore Line group. Do a search within Yahoo Groups for \"CNSMRR.\" Though the group is technically for North Shore Line discussions they do go off topic and this is an example.
The branch line was in place but out of service into the late 1980s from what I recall. Around 1990 the city replaced the grade crossing where the tracks crossed California with a new, rubberized grade crossing though it had been years since a train went down those tracks.
I\'ve heard the line referred to various ways, including the Avondale line. It also served other C&NW customers farther west, around Kimball. A fairly recent spur is still in place if you look hard though it is disconnected. Again, it was built relatively recently and apparently after rail service was already stopped.
