Beginning Sunday, June 12, the Chicago Transit Authority adjusted the hours of operation on the Green, Orange and Brown lines in an effort to provide earlier service to Midway Airport for travelers on weekends, provide more convenient transfers between rail lines and accommodate increases in ridership.

In addition, all eight rail lines have new schedules in effect. Most routes continue to have the same general frequency and span of service; however, arrival times may change up to a few minutes.

Green Line
On Saturday and Sunday mornings, service between Harlem and Cottage Grove/63rd and from Harlem to Ashland/63rd will begin approximately 30 minutes earlier. Service from Ashland/63rd to Harlem will begin at approximately 5:15 a.m.

Brown Line
On weekdays and Saturday mornings, the first train downtown will leave Kimball 30 minutes early and the first train from downtown to Belmont will leave 30 minutes early. The last train from Kimball to downtown and the last train from downtown to Kimball will leave 30 minutes earlier as well.

Orange Line
On Sunday mornings and evenings, the first train from downtown to Midway Airport will leave one hour earlier and the last train to Midway from downtown will leave an hour and a half earlier. The first train from Midway to downtown leaves one hour earlier and the last train to downtown from Midway leaves at approximately 1 a.m.
