The Chicago Transit Authority (CTA) has begun Phase Three of its track renewal program from Lee St. to Church St. which is expected to be completed on September 26.

The CTA announced this heavy maintenance renewal track project in April 2013. The project work on the Purple Line in the City of Evanston is designed to help remediate slow zones along the line. It will replace over 6,000 railroad ties that are beyond their useful life and extend the life of the line until permanent funding is secured for full Red & Purple Line Modernization. This will be the first major upgrade to the Purple Line railroad ties since 1976.

The ultimate goal of the project is to speed up service for riders by eliminating slow zones on the Purple Line. The replacement work will be done by CTA staff and began in south Evanston and will continue to the north. The work schedule is as follows:

  • Sunday, July 14 through Thursday, September 26, Sunday – Thursday, nightly 9 p.m. – 4:30 a.m.      next day. No work Monday, September 2 for Labor Day Holiday.
  • Saturdays and Sundays only July 20 through September 22, 7 a.m. – 7 p.m., each day.

Trains will operate on a single track at Dempster and Davis stations. There will be noise while the work is being performed. Noise may include: engine noise from diesel track maintenance equipment; beeping from back-up alarms on track maintenance equipment; crunching rock; and metal on metal hammering. There will be light in the work zone and possible delays to train service along the Purple Line. There will be lane closures and parking restrictions during weekend work.

CTA will distribute flyers to residents prior to work in affected neighborhoods. Residents can find more information on this project or sign up for e-mail updates (right sidebar of page) by visiting
