The Chicago Transit Authority (CTA) operates the nation’s second largest public transportation system. On an average weekday, 1.6 million rides are taken on CTA. The CTA is a regional transit system that serves 35 suburbs, in addition to the City of Chicago, and provides 81 percent of the public transit trips in the six-county Chicago metropolitan area either with direct service or connecting service to Metra and Pace.
CTA has 1,864 buses that operate 129 routes and 1,536 route miles. Buses make about 19,237 trips a day and serve 10,768 bus stops.
On the rapid transit system, CTA’s 1,492 rail cars operate eight routes and 224.1 miles of track. CTA trains make about 2,318 trips each day and serve 145 stations.
Chicago is one of the few cities in the world that has rail service to two major airports. CTA’s Blue Line ‘L’ can take customers to O’Hare International Airport. Orange Line trains, which operate clockwise on the Loop ‘L’ structure, travel to Midway Airport.
CTA also provides around-the-clock service on certain routes. During late night and early morning hours, major rail lines and some of CTA’s bus routes offer “Night Owl” service, much of it with connecting schedules and routing.
Chicago Transit Authority is an independent governmental agency created by state legislation. CTA began operating on Oct. 1, 1947, after it acquired the properties of the Chicago Rapid Transit Company and the Chicago Surface Lines. On Oct. 1, 1952, CTA became the predominant operator of Chicago transit when it purchased the Chicago Motor Coach system.
The Mayor’s appointees are subject to the approval of the Governor and the Chicago City Council; the Governor’s appointees are subject to the approval of the Mayor and the Illinois State Senate. CTA’s day-to-day operations are directed by Dorval R. Carter, Jr., president.
CTA generates revenue from both farebox collections and nonfarebox revenues, and also receives supplemental funding for operating expenses through 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 suburban rail system) and Pace (the suburban bus system) — to recover collectively at least 50 percent of operating costs from farebox and other system revenues.
