Green Line West Track Renewal Project

Track rehabilitation project will provide customers a smoother, more reliable commute for years to come


The Green Line West Track Renewal Project is rehabilitating aging track infrastructure between Laramie and Harlem/Lake stations.

The project is one of the biggest transit investments on Chicago’s West Side in the past 20 years and will replace rails and ties and make other track improvements to provide smoother, more reliable rides.

The work is a proactive effort to avoid the development of future slow zones in the area, which results in reduced reliability and increased travel times. The last major track renewal work along this 2.5-mile stretch of tracks occurred in the 1980s and more than 75 percent of the rail ties are approaching or have exceeded their useful life.

In 2014, the Green Line stations on the Lake Street branch had more than 9 million riders.

Project Schedule & Service Impacts

On select weekends beginning April 1, Green Line service will operate between Ashland/63rd and Cottage Grove to Laramie instead of continuing to Harlem/Lake. CTA will operate free shuttle buses to serve the impacted stations during the temporary weekend impacts.

The work will occur over a total of seven weekends and the project will reach substantial completion in June 2016. We recommend that riders allow extra travel time during weekends when work occurs.

See below for upcoming/current Green Line service alerts, or subscribe to planned weekend service changes from CTA Updates to have advance notice of work e-mailed to you.

As with all large-scale projects, we'll strive to minimize impacts to service and the surrounding community.

What is included in the work?

The work in this project includes:

  • Replacement track ties between Laramie and Harlem/Lake stations
  • Replacement tie plates and fasteners
  • Maintenance to running rails
  • Adding new ballast (the stone/earthen material that holds the ties in place)

Why is work needed?

The work will prevent imminent slow zones from developing in the corridor due to the aging track conditions. Slow zones, or areas of track where speed must be reduced, impact the speed and reliability of service to customers.

The last major track renewal work along this 2.5-mile stretch of tracks occurred in the 1980s and more than 75 percent of the rail
ties are approaching or have exceeded their useful life.

The Green Line Lake branch had more than 9 million rides in 2015.
