St. Charles Air Line constructed by IC, authorized by city ordinance passed 1855; owned jointly by: Elevation completed 1898-1899
 * Chicago, Burlington and Quincy Railroad &rarr; Burlington Northern Railroad &rarr; BNSF Railway
 * Galena and Chicago Union Railroad &rarr; Chicago and North Western Railway &rarr; Union Pacific Railroad
 * Illinois Central Railroad
 * Michigan Central Railroad &rarr; sold to IC by 1996


 * Connections, west to east (all remained both before and after elevation)
 * Joint CB&Q/C&NW at west end
 * 16th Street interlocking
 * Southeast quadrant connection with Chicago and Western Indiana Railroad (and its tenants) and Chicago and Alton Railroad
 * C&WI connection probably disappeared during elevation
 * C&A connection was gone by 1952, and seems to have always been redundant to CM&N connection (but it was trivial to build because of the connection between the C&A and joint LS&MS/CRI&P crossing the SCAL at-grade - why did this exist? The C&A originally used LaSalle Street Station, but moved out long before elevation)
 * Southeast quadrant connection with Chicago, Madison and Northern Railroad (&rarr; IC) and Atchison, Topeka and Santa Fe Railway
 * AT&SF connection probably disappeared during elevation, which is probably when the AT&SF and CM&N lines were combined through Alton Junction
 * Northwest and southwest quadrant connections with joint Lake Shore and Michigan Southern Railway/Chicago, Rock Island and Pacific Railroad (New York, Chicago and St. Louis Railroad trackage rights)
 * IC (MC trackage rights) at east end
