Next month, MARTA will continue its Track Replacement Phase IV (TR-IV) program with a major effort that will temporarily suspend rail service between Buckhead, Lenox, and Lindbergh Center stations and create significant service delays for some customers. Beginning February 16 at 9 p.m., through February 22 at 4 a.m., MARTA’s rail customers traveling through the affected stations will experience up to 30-minute service delays due to the track replacement effort.
