The Chicago & Northern Pacific was leasing the Wisconsin Central. In my 1893 Official Guide, through trains were not in the time table. You had to get off and get on at either St.Paul or Minneapolis.
The Northwestern Station at Madison was still in the future. The Northwestern Station was across the river on Wells Street, the original route of the CNW into Chicago.
In 1893, the New York Chicago and St.Louis also had a station to itself, sort of squeezed in between the Van Buren station (later to become LaSalle) and Dearborn station.
Part of the G&IR (Galena & Illinois River) was used by the Panhandle, finally to become the Pittsburgh Cicinnati Chicago & St.Louis. It entered the Chicago Union Passenger Station from the north using the Milwaukee tracks. As it wandered northward along Western Avenue toward the Milwaukee Road, it had a commuter station around Madison Ave; through trains to the east ignored it
In 1893 the ‘Chicago Railroad Association’ had 23 members, among them the Goodrich Transportation Company that ran a bunch of steamships on Lake Michigan.
In the index of stations, Chicago had 22 railroads using 7 stations: Dearborn, Grand Central, Union, C&NW, Van Buren (later LaSalle), NYC&StL, and Central (at 12th St).
The railroads: ATSF, B&O, C&A, C&EI, Chicago & Grand Trunk, Chicago & Northern Pacific, C&NW, Chicago & Western Indiana, CB&Q, Chicago Great Western, CM&StP, CRI&P, CCC&StL (Big 4), Erie, IC, Lake Shore & Mich.Southern, LNA&C (Monon), Michigan Central, NYC&StL, Pennsylvania, Wabash, Wisconsin Central.
