Chicago Orange Line Adapts for Track Upgrades

Chicago Orange Line switches to single track between Western and Pulaski stations

Orange Line Adds Single-Track Between 2 Stops

Chicago's Orange Line will operate on a single track between Western and Pulaski stations starting September 3, transit officials said. The change affects one of the city's busiest rail corridors, with the Orange Line carrying approximately 28,000 riders on an average weekday. Officials haven't said when normal two-track service will resume.

Background

Single-track operations are a common temporary measure transit agencies use during track maintenance or repair work, allowing service to continue while work is performed on the adjacent track. The CTA hasn't provided details about the nature of the track work necessitating the single-track operation. The Orange Line opened in 1993 and connects downtown Chicago to Midway Airport, making ongoing track maintenance a routine necessity for the 30-year-old infrastructure. The affected section between Western and Pulaski serves several Southwest Side neighborhoods.

Service Details

Trains will share one track in both directions between the two stations, requiring trains to wait for each other to pass. The CTA advises riders to allow extra travel time but hasn't specified expected delay durations. Passengers should check station signage carefully for boarding changes, as platforms may differ from normal operations during this period. Officials said the high-severity alert means riders with time-sensitive appointments should plan accordingly.

Timeline

The single-track operation begins September 3, 2025, according to the transit agency. The CTA hasn't announced when normal two-track service will resume on this section of the Orange Line. Officials posted the service alert on the agency's website, though the exact announcement date wasn't specified.

Rider Impact

The service change will cause boarding changes and delays for passengers traveling through the Western-Pulaski section. Those with time-sensitive appointments or connections should consider allowing additional time for their commute. Riders can check real-time service updates and track Orange Line schedules through Moovit to plan their trips and monitor any additional delays during the single-track operation period.
