The Lake–Dan Ryan Line was a rail rapid transit route formerly operated by the Chicago Transit Authority (CTA). The Lake–Dan Ryan Line existed from the opening of the Dan Ryan branch on September 28, 1969, until February 21, 1993. When created, the route united two transit corridors that until 1969 never had through rail service. This routing, which became known as the West-South route, operated from the Harlem terminal in Forest Park on the Lake Street "L" through downtown Chicago along the Union Loop "L", and then via the old South Side "L" and the new Dan Ryan Line to the 95th Street Terminal. The Lake–Dan Ryan service was planned in conjunction with the former Franklin Street Connector and Chicago Central Area Transit Project, both of which were never constructed. The section of the route between the junction with the South Side "L" at 17th and State Streets and the Cermak–Chinatown Station was originally an "interim", or temporary facility. It was planned to be torn down when the Loop Subway system was completed, but survived after the project was canceled in 1979. That section was improved in the 1980s and early 1990s and is currently being used by the Orange Line. Train transfers are possible by using the two unused tracks.
