Avondale is a train station in Decatur, Georgia. It is on the Blue Line of the Metropolitan Atlanta Rapid Transit Authority (MARTA) rail system. The station is at-grade and has two island platforms, one for each direction. The center two tracks are not normally used for through service. Because of these middle tracks, it is not uncommon for trains to be bound for Avondale, having passengers change trains at Avondale. A limited number of Green Line trains originate and terminate at Avondale rather than at their normal terminus at Edgewood / Candler Park, though these trains bypass East Lake and Decatur.
