Editing Green Line (CTA) (section)

===Lake Street Elevated===
{{main|Lake Street Elevated}}
Beginning at the yard and inspection facilities in [[Forest Park, Illinois|Forest Park]], the Green Line runs east through [[Oak Park, Illinois|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 diverge from 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 Union Pacific's Rockwell Subdivision) before entering downtown Chicago at Clinton Street. East of Clinton Street, the route bridges [[Metra]]'s [[Union Pacific Railroad|Union Pacific]] railroad tracks (which terminate just south of here at [[Ogilvie Transportation Center]]) and the [[Chicago River]] before joining the Union [[Chicago Loop|Loop]] "L" tracks at Wells Street.
