Chicago Orange Line Adapts Service for Track Work

CTA Orange Line to run single track between Kedzie and Midway stations starting July 21

Orange Line Adds Single-Track Service July 21

Chicago's Orange Line will operate on a single track between Kedzie and Midway stations starting July 21, the Chicago Transit Authority said. The change affects one of the system's busier routes, carrying about 28,000 riders on an average weekday. Passengers should expect altered boarding procedures and minor delays, though officials didn't specify how long the single-track operation will last.

Context and Background

The Orange Line connects downtown Chicago to Midway International Airport and Southwest Side neighborhoods across 13 miles and 18 stations, according to CTA data. Single-tracking is a common temporary measure transit agencies use during track maintenance or infrastructure work, requiring trains in both directions to share one track. The CTA didn't specify the reason for the single-track operation. Officials said passengers may need to board from different platforms than usual during the service modification.

Key Details

The affected segment runs between Kedzie and Midway stations, including intermediate stops like Pulaski. Transit officials characterized expected delays as 'minor' but didn't provide specific time estimates. The Orange Line ranks as CTA's fourth-busiest rail line among eight routes, behind the Red, Blue, and Brown lines. Dorval R. Carter Jr., CTA President, oversees the agency's operations, though officials weren't immediately available for comment about the service change.

Timeline and Implementation

The single-track operation begins July 21, 2025, according to the transit agency's service alert. The CTA hasn't announced when normal two-track service will resume. Officials said they'll provide updates through the agency's alert system, but a timeline for when additional information will be available wasn't specified. Transit agencies typically notify riders several weeks before major service changes.

Rider Impact and Information

Passengers with time-sensitive appointments or flight connections to Midway Airport should allow extra travel time, officials said. Riders should pay attention to station announcements and platform signage, as boarding locations may differ from normal operations. The CTA recommends considering alternative routes where possible during the service modification. Moovit provides real-time updates and service alerts for CTA Orange Line routes to help riders plan their trips during the single-track operation.
