Word on the street is that if Clayton votes to join MARTA this November, the timeline would be:
-March 2015: first bus service (extension of existing routes)
-July 2015: Six new bus routes begin service; two "flex route" shuttle/circulator services begin, paratransit service begins. Routes will have 30min and 60min headways.
-2020: Final two bus routes begin service; additional "flex route" service begins.
-2022: Rail service begins, with 7 new stations - East Point (adjacent and connected to existing East Point station), Hapeville, Mountainview/Airport, Forest Park/Fort Gillem, Clayton State University, Morrow/Southlake, and Jonesboro. Rail will largely use the existing Norfolk Southern right-of-way, which is 100ft wide.
-2025: Full paratransit service in effect for entire service area; planning for rail extension to Lovejoy.

Pretty exciting to have rail by 2022. Sounds like commuter rail, as it will have grade crossings. Could run on its own track or share with freight. 15 min or 30 min headways during peak hours; may or may not have service outside of peak hours.
