Looking at the classic book "Train Watchers Guide to Chicago (3rd Edition), the author, John Szwajkart (try typing that quickly) states "BRC rails were used throu 80th Street, and Forest Hill to reach the C&O's Rockwell Street Yard".
Further the book states "The road's major yard (C&O) was Rockwell Streeet Yard near 75th and Kedzie. This facility was leased from teh BRC and a small engine terminal was located at the west end under the Kedzie overpass."
The map which accompanies the book shows the Rockwell Street Yard to be on the north of the BRC line.
Hope this helps,
Ed
