Station was owned by Chicago Union Station Co., which was jointly owned by the four railroads using the station. Union Station trackage extended south to the beginning of trackage of three separate railroads. While trackage north and west extended to Tower A-2 (Western Avenue). Tower A-2 was the beginning of the Milwaukee Road, operating most trains using the north end of Union Station. Extending south of Tower A-2 was the Pennsylvania Railroad's Pittsburgh Cincinnati Chicago & St. Louis line. But eventually, all trains using that line used the Pennsylvania Railroad's Pittsburgh Fort Wayne & Chicago line south of Union Station.
Through mergers, Burlington Route is now part of BNSF, former Alton Route trackage is now owned by CN and Union Pacific, most remaining Pennsylvania Railroad trackage is now part of Norfolk Southern, and most remaining Milwaukee Road trackage is now part of Canadian Pacific.
Passenger service continues under Amtrak.

Pennsylvania Railroad (Pittsburgh Cincinnati Chicago & St. Louis)
Passenger service originally discontinued in 1971 with the creation of Amtrak. Service resumed shortly afterward, due to deteriorated track conditions on what had become Penn Central Railroad between Kankakee and Indianapolis. Service permanently discontinued in 1975 after track conditions on this line had deteriorated.
Consolidation of Pennsylvania Railroad eventually resulted in all train using Pittsburgh Fort Wayne & Chicago line between Union Station and Colehour Jct., and SC&S Branch between Colehour Jct. and Bernice, where connection was made with this main line. Between 1980 and 1993, Amtrak used this route to connect with the former Monon line at Munster.
