The CTA is focused on making its ETA. The Chicago Transit Authority operates the second-largest public transportation system in the US, behind the New York City Transit Authority. On a typical weekday, CTA passengers take about 1.7 million rides on the agency's buses and trains, which travel in and around Chicago and about 35 suburbs. The CTA operates a fleet of 1,865 buses on almost 130 routes. Its rail system includes eight rail lines with some 1,356 rail cars operating on 224 miles of track at more than 145 stations. The agency, created by the Illinois legislature in 1947, is part of the state's Regional Transportation Authority, which also oversees Metra (commuter rail system) and Pace (suburban bus system).
