Red Line:
Work on the Red Line subway between Clark/Division and Grand, between Wilson and Sheridan, and on the southbound track between Morse and Loyola was completed in 2007. Progress was made on all four tracks (Red and Brown lines) between Armitage and Diversey during 2007.
Slow zone elimination on the remaining portion of the Red Line subway is underway. All construction between Clark/Division and Roosevelt is complete. Track upgrades between Clark/Division and the north end of the Red Line subway continues and will be complete by the end of 2008.
Track improvement work on all four tracks (Red and Brown lines) between Diversey and Wellington is currently underway and will be complete by the end of 2008. Work between Belmont and Sheridan stations is expected to be completed in Summer 2009.
Loop Elevated:
Slow zone elimination and track renewal is underway on the Lake Street and Wabash Avenue sides of the Loop Elevated in downtown. Work began in May 2008 and will resume in September 2008.
Construction involves the upgrade of approximately 10,000 feet of track. When the project is completed at the end of 2008, customers will experience more reliable and efficient rail service.
While work is underway, one or both tracks on the Lake and Wabash sides of the Loop Elevated will close on:
- Weekends (10 p.m. Friday until 4 a.m. Monday)
- Weeknights (10 p.m. until 4 a.m. the following morning)
During periods when the Lake and Wabash sides of the Loop Elevated are closed, all trains that normally operate on the Loop during night and weekend hours – the Orange, Green, Pink, and Brown lines – will operate on the Wells and Van Buren sides of the Loop, making all stops. Three types of track closures will require rail service to be rerouted in the Loop:
- Both Tracks Closed: Brown, Green, Pink and Orange line trains will operate on the Wells and Van Buren sides of the Loop.
- Inner Loop Track Closed Only: Orange and Pink line trains will operate on the Outer Loop track – the same side regularly used by the Brown Line. Southbound Green Line trains will operate on the Wells and Van Buren sides of the Loop.
- Outer Loop Track Closed Only: Brown Line trains will operate on the Inner Loop track– the same side regularly used by the Orange and Pink lines. Northbound Green Line trains will operate on the Wells and Van Buren sides of the Loop.
When trains are rerouted to the Wells and Van Buren sides of the Loop, free, accessible transfers can be made between the Library and Jackson stations.

Slow zone elimination work began in 2007 on all four tracks (Red and Brown lines) between Armitage and Diversey. Work on all four tracks (Red and Brown lines) between Diversey and Wellington is currently underway and will be complete in Fall 2008.
Construction to eliminate slow zones between Southport and Western stations began in May 2008. During construction, trains may be rerouted during nights and weekends, sharing one track in both directions. Work between Southport and Western will be complete by the end of 2008.
