Connecting lines

Getting to and from the West Loop

From most of the West Loop, the Green Line is the fastest way to the Loop — Morgan, Clinton, or Ashland to Clark/Lake is a single stop, about three minutes. For South Side trips (the IIT campus at Bronzeville, the Bears training facility at Halsted, the South Loop), the Green Line is also the natural choice: take it east into the Loop and stay on as it dips south. For Oak Park, take it west from Ashland.

Frequently asked questions

What Green Line stations are in the West Loop?
The Green Line serves four stations within the West Loop: Ashland (also Pink Line), Morgan (also Pink Line), Clinton (also Pink Line), and Damen (Green Line only — opened in 2024). All four sit on the elevated tracks above West Lake Street.
Does the Green Line go downtown?
Yes. The first stop east of Clinton is Clark/Lake, which sits in the Loop and connects to every other L line. Travel time from Clinton to Clark/Lake is about three minutes.
Does the Green Line run 24 hours?
No. Only the Red Line and the Blue Line offer 24-hour L service in Chicago. The Green Line operates roughly 4 AM to 1 AM. For overnight transit, the closest 24-hour L from the West Loop is the Blue Line at Clinton or UIC-Halsted.
What's the difference between Damen Green Line and Damen Blue Line?
They're two different stations on two different lines, both named Damen. The Green Line Damen station opened in 2024 at Damen and West Lake Street, on the elevated tracks. The Blue Line Damen station has existed for decades at Damen and North Milwaukee in Wicker Park, several miles north. They are not connected.
How do I get from the Green Line to Union Station or Ogilvie?
Get off at Clinton (Green/Pink Line) and walk south on Clinton Street. Union Station is about a five-minute walk; Ogilvie Transportation Center is even closer. The Clinton Green/Pink station is the West Loop's most useful connection point between the L and Metra.
Where can I transfer to other lines from the Green Line?
Within or near the West Loop, the practical transfers are: Clinton Green/Pink to the Blue Line (one-block walk to Clinton Blue Line station), and Clark/Lake (one stop east of Clinton) to every other L line. The Pink Line shares Green Line tracks west of Ashland Junction so transfers between Green and Pink within the West Loop are seamless.
