The CTA is an Illinois independent governmental agency[1] that started operations on October 1, 1947 upon the purchase and combination of the transportation assets of the Chicago Rapid Transit Company and the Chicago Surface Lines streetcar system. In 1952, CTA purchased the assets of the Chicago Motor Coach Company, which was under the control of Yellow Cab Company founder John D. Hertz, resulting in a fully unified system.

Today, the CTA is one of the three service boards financially supported by the Regional Transportation Authority.
