Puting Rapid Back in Transit CTA Home CTA Home Help CTA Home

  The Chicago Transit Authority has launched an aggressive project to eliminate slow zones on its rail system. Work to eliminate slow zones includes replacing wood rail ties and old tie plates with 100 percent recycled plastic ties and insulated tie plates; and replacing track. The project, once completed, will provide:
  • Faster Trips
  • More Reliable Service
  • A Better Commute
As of September 2, 2008, slow zones on CTA’s rail system have been reduced to 10 percent. In Summer 2007, the agency announced an ambitious plan to eliminate slow zones in the State Street and Dearborn subways and on the O’Hare branch of the Blue Line. A total of 141,577 feet of slow zones have been removed from a high point of 22.3 percent (263,526 feet).

The construction work will impact travel during off peak hours and will involve weekend and night closures in some areas. For the latest service advisories, click on the links below.

Blue Line:

Work on the downtown subway portion of the Blue Line was completed in September 2007.

Work on the O’Hare branch of the Blue Line between O’Hare and Addison is currently underway. Since 2007, 65,800 feet of slow zones have been removed between Jefferson Park and O’Hare. During construction, reroutes and bus substitutions will be necessary to allow work to proceed.


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 on September 3, 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.

Service Impact

While work is underway, one or both tracks on the Lake and Wabash sides of the Loop Elevated will temporarily close. Green, Pink, Orange and Brown Line trains may be rerouted during the following times:

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.

Community Impact

  • While work is underway, lane closures will occur.
  • There will be some noise during construction.

Project Information


Brown Line:

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.
