How does this affect my trip? 10:30pm Thu to 12:01am Fri: Board/exit all trains on the Loop-bound side of the platform at the Ashland station. Fri, 12:01am to 2am: Board/exit all trains on the Loop-bound side of the platform at the Halsted and Ashland stations. Trains in both directions will operate on the same track between Halsted and 35th/Archer, resulting in minor delays. Allow extra travel time. Why is service being changed? We are performing track maintenance to ensure that trains continue to operate safely along the Orange Line.
