Photos are included, where available, showing remaining evidence of some of these discontinued stations.
Within Illinois, nearly all lines either presently have or previously had commuter service in and out of Chicago. Commuter service was eventually discontinued on some lines, while surviving commuter service is now operated by Metra. And a few commuter lines previously extended into Wisconsin, with all service in Wisconsin eventually discontinued except to Kenosha.

Chicago Track Elevation
One significant development affecting the history of railroad stations in Chicago, occurred mostly between the 1890's and the early 1900's. During that time, city ordinances required many railroads to elevate their rights of way. Resulting in the replacement or reconfiguration of many stations.
Additional information is from various issues of "The Official Guide of the Railways", and from various actual railroad timetables.
