context_page_description: The Green Line is a rapid transit line on the Chicago Transit Authority's "L" system. It is the only completely elevated route in the entire system; all other routes either have underground sections or sections at grade. It utilizes the system's oldest segments, extending 20.695 miles with 30 stops between Oak Park and Chicago's West Side, to the Loop, and then to the South Side and West Englewood and Woodlawn.
context_section_description: Beginning at the yard and inspection facilities in Forest Park, the Green Line runs east through Oak Park towards the city on an embankment adjacent to Metra's Union Pacific/West Line tracks from the Harlem Avenue terminal, on the border of Oak Park and Forest Park, to a point just west of Laramie Avenue. Here the Green Line tracks leave the railroad embankment and continue east on a steel elevated structure directly above Lake Street, a major east–west thoroughfare. The "L" bridges a couple of railroad tracks (The Belt Railway of Chicago's main line and UP's Rockwell Subdivision) before entering downtown Chicago at Clinton Street. East of Clinton Street, the route bridges Metra's Union Pacific railroad tracks (which terminate just south of here at Ogilvie Transportation Center) and the Chicago River before joining the Union Loop "L" tracks at Wells Street.
