Much of the CIS was graded but never laid, so the chart is a bit deceiving. I have the original GTW track chart for the CIS that was issued immediately after its construction - I'll see if I can dig it up and post it. Nothing left today, save for the one leg headed to the Ford Trim/Metro Aluminum/Kroger warehouse, and even that has been greatly simplified to the one track that heads directly north on the east side of the building. Bits and pieces of track remain deep in the weeds just west of the CN main, however, this is difficult to explore given that the property owners are extremely hostile toward trespassers, and you are being monitored by dozens of surveillance cameras back there in 2017. Who knows what the future holds here, as someone paid a heavy price to keep the switch intact during the recent CTC/PTC construction - which required a heavy duty electric lock mechanism installed.
All this said, the railroad and crews now refer to the PolyOne spur as the "CIS". As George Patton once spoke in no uncertain terms - "all glory is fleeting"...
