CTA Green Line Track Work Maintains Safety
CTA Green Line single-tracking between Harlem and Central stations overnight April 6-7
CTA Green Line Delays Set for Track Work
Chicago's Green Line riders face overnight delays and boarding changes as track maintenance forces trains in both directions to share a single track between Harlem and Central stations. The Chicago Transit Authority said the work runs from 10 p.m. Monday, April 6, 2026, through 3:45 a.m. Tuesday, April 7, 2026. Passengers at Oak Park, Ridgeland, and Austin stations must board and exit all trains on the Harlem/Lake-bound platform side during this period.
Safety Maintenance Drives Service Change
The track work is necessary to ensure trains continue operating safely along the Green Line, transit officials said. Single-tracking between stations is a common maintenance strategy that allows crews to work on one track while trains use the other, though it typically results in slower service and longer wait times. The CTA didn't specify what type of track maintenance will be performed during the overnight work window. Transit agencies typically schedule such work during late-night hours to minimize rider impact.

Three Stations See Platform Changes
Oak Park, Ridgeland, and Austin stations will require all passengers to use only the Harlem/Lake-bound platform for boarding and exiting in both directions during the maintenance period. The single-track operation between Harlem and Central will cause minor delays as trains wait for opposing traffic to clear before proceeding. Train Tracker arrival estimations will also be affected during the work period, officials said. The CTA advised riders to allow extra travel time if traveling through the affected section overnight Monday into early Tuesday morning.

Work Ends Early Tuesday Morning
The service modifications begin at 10 p.m. Monday, April 6, 2026, and are scheduled to conclude at 3:45 a.m. Tuesday, April 7, 2026. Normal two-track operations and standard boarding procedures are expected to resume after the work window closes. The CTA said the work is part of ongoing maintenance to keep the Green Line operating safely, though officials didn't provide details on whether additional overnight work sessions are planned for the same section.
Riders Advised to Plan Ahead
Passengers traveling on the Green Line during the overnight maintenance window should expect minor delays and remember to use only the Harlem/Lake-bound platform at the three affected stations. The CTA recommends checking current alerts and system status before traveling, as multiple other lines including the Blue, Brown, and Purple lines are also experiencing service changes.
