The Chicago Transit Authority (CTA) operates one of the nation’s largest public transportation systems and covers the City of Chicago and 35 surrounding suburbs. On an average weekday, 765,566 rides are taken on CTA.
The CTA is an independent governmental agency created by state legislation. We began operating on October 1, 1947, after acquiring the properties of the Chicago Rapid Transit Company and the Chicago Surface Lines. On October 1, 1952, CTA became the sole operator of Chicago transit when it purchased the Chicago Motor Coach system.

In addition to CTA, regional transit services are also provided by our sister agencies, Metra and Pace—both of which connect with CTA bus and rail in numerous locations. You can read more about regional and national services that connect with CTA in our page about Regional Connections.
Most rides on CTA are taken by bus. Our bus system consists of 128 routes. Buses make over 25,000 trips daily, and serve nearly 12,000 bus stops throughout the region.
CTA bus routes serve communities locally, move people across town, and a number of express services are provided. Several routes also provide 24-hour service, known as "Owl Service."

Our rail system, known as "The 'L'", consists of train lines spanning the city and neighboring communities. The service provided is described as "heavy rail rapid transit," also referred to as a "subway" or "metro" in many parts of the world.
The 'L' system has eight rapid transit routes and consists of 145 stations over approximately 224.1 miles of track. Parts of the 'L' run above ground, in subway tunnels and tubes, as well as at grade or in expressway medians.
Two routes—the Red and Blue Lines—operate 24 hours, every day.
The nickname 'L' is short for "elevated," a reference to the all-elevated beginnings of the system (even though, as just mentioned, parts of the system today are at or below ground).
Free transfer between all 'L' routes is available at designated locations (see maps or route info for free transfer locations).

The CTA generates revenue from farebox collections and also receives supplemental funding for operating expenses from the Regional Transportation Authority (RTA).
The complete Budget documents are available under Finance/Budget.
The Regional Transportation Authority (RTA)
The RTA was established in 1974 to oversee local transportation operators in the six-county Chicago metropolitan area. Illinois state law requires the three RTA service boards - CTA, Metra (the region's commuter rail system), and Pace (the suburban bus system) to recover collectively at least 50 percent of operating costs from farebox and other system revenues. The RTA provides public funding for the agencies' remaining operating expenses.
