Not covered are CTA rapid transit lines, and abandoned electric interurban lines. Not shown are certain interlockings, often short lived, with limited histories and where the exact locations could not be verified. Also not included are drawbridges which were not interlocked.

Roundhouses were usually located near the downtown Chicago passenger terminals, and at railroad freight yards. These are where locomotives were turned and serviced. In addition, turntables were formerly located in various suburbs, where commuter trains turned. With the adoption of push pull trains on what is now Metra, these turntables are no longer necessary. Not all locations had turntables. Either locomotives were generally bidirectional switchers not requiring turning, or wye tracks existed for turning trains or locomotives.
