The '''Green Line''' is a rapid transit line in [[Chicago]], [[Illinois]], operated by the [[Chicago Transit Authority]] (CTA) as part of the [[Chicago "L"]] system. It is the only completely elevated route in the "L" system. All other routes may have various combinations of elevated, subway, street level (at grade), or freeway median sections.<ref>[http://world.nycsubway.org/us/chicago/green.html World.nycsubway.org – Chicago Green Line]</ref> This line is also the only route with three terminals: trains departing Harlem/Lake alternate destinations between Ashland/63rd and Cottage Grove.

The Green Line utilizes the system's oldest segments, dating back to 1892. It extends for {{convert|20.695|mi|km}}, with 31 stations between [[Oak Park, Illinois|Oak Park]]/[[Forest Park, Illinois|Forest Park]] (Harlem/Lake) and [[Chicago, Illinois|Chicago's]] [[West Side, Chicago|West Side]], to the [[Chicago Loop|Loop]], and then to the [[South Side, Chicago|South Side]] neighborhoods of [[West Englewood, Chicago|West Englewood]] (Ashland/63rd) and [[Woodlawn, Chicago|Woodlawn]] (Cottage Grove/63rd).
