CTA Blue Line subway platform in Chicago is part of the Milwaukee-Dearborn Subway, the downtown tunnel used by Blue Line trains through the Loop. The subway opened in 1951 and carries trains between O'Hare International Airport, downtown Chicago, and the Forest Park branch. Its arched tunnel and side platform are typical of Chicago's mid-20th-century rapid transit construction.
