The Red Line is a rapid transit line in Chicago, run by the Chicago Transit Authority (CTA) as part of the Chicago "L" system. It is the busiest line on the "L" system, with an average of 108,303 passengers boarding each weekday in 2023^[1] The route is 21.8 miles (35.1 km) long with a total of 33 stations. It runs elevated from the Howard station in the Rogers Park neighborhood on the North Side, through the State Street subway on the Near North Side, Downtown, and the South Loop, and then through the Dan Ryan Expressway median to 95th/Dan Ryan in the Roseland neighborhood on the South Side.

Like Chicago's Blue Line, the Red Line runs 24 hours a day, 365 days a year, making Chicago, New York City, and Copenhagen the only three cities in the world that operate train service 24 hours a day throughout their city limits.^{[citation needed]}

The CTA is planning an extension of the Red Line, adding 5.6 miles (9.0 km) and four new stations which would extend the line from 95th Street to 130th Street, making the Red Line approximately 31 miles in length with 37 stations.^[2] In December 2022, the Chicago City Council approved the creation of a district that will send approximately $1 billion in tax revenue for the extension of the Red Line south of 95th Street to 130th Street.^[3]
