Control system
All rapid transit lines have an ultimate nexus at the Five Points station, located in downtown Atlanta. MARTA trains are operated using the Automatic Train Control system, with one human operator per train to make announcements, operate doors, and to operate the trains manually in case of a control system malfunction or an emergency. Many of the suburban stations have free daily and paid long-term parking in park and ride lots. These stations also have designated Park and Ride passenger drop-off areas close to the stations' entrances.
