This is a collection of Chicago rapid transit track maps. The historic maps are digitized as they were originally published. The contemporary track maps were rendered for Chicago-L.org.

Although the current track maps are largely broken up based on different routes, they are not route maps per se, showing the logical routings of the passenger trains. They are only track maps, showing the physical tracks making up the rapid transit system. Route maps, both historical and current, are available here.

Although all but the current system map are less than 200k, some browsers may have difficulty viewing the larger images. If you have trouble viewing any of the maps in your browser, we suggest downloading and viewing them offline in some other viewer (such as Photoshop, JPEGview, or Photo Editor) rather than viewing them online.
