The Gold Line is a rapid transit line in the MARTA rail system. It operates between Doraville and Airport stations, running through Doraville, Chamblee, Brookhaven, Atlanta, East Point and College Park.
What is now the Gold and Red Lines' shared section was originally opened on December 4, 1981, as the North-South Line between and . On September 11, 1982, an infill station at opened, while the North-South Line was extended south by one stop to West End station. On December 18 the same year, the North-South Line was extended northward to and . On December 15, 1984, the , , , , and Brookhaven (now ) stations all opened, with the last two being the first stations on what would become the Gold Line branch. East Point station opened on August 16, 1986, followed by on December 19, 1987, and the and on June 18, 1988. The newest and northernmost station on the line, , opened on December 29, 1992.
On June 8, 1996, MARTA added a new branch of the North-South Line, with stations at , , and . To distinguish the two lines, the line to Dunwoody assumed the North-South Rail Line name, while the line to Doraville became the Northeast-South Rail Line (sometimes known as the Northeast Line for short). However, both the North-South Line and the Northeast Line continued to be colored on maps in orange as a single North-South Rail Line until December 2006, when the North-South Line began to be colored as red, and the Northeast Line as orange.
In October 2009, MARTA introduced a color-coded system of naming rail lines, with the Northeast Line being renamed to the Yellow Line, and the color orange falling out of use. However, in February 2010, the name was revised to Gold in order to address a concern among the Asian-American community in Doraville, which the line serves.
On March 25, 2024, Andre Dickens, the mayor of Atlanta, announced plans for four new infill stations on the MARTA rail network, with one of them, Murphy Crossing, being a station on the Red and Gold Lines' shared section. Murphy Crossing will be on the west side of the Atlanta Beltline. On April 11, Dickens announced that another one of the four proposed stations will also be shared by the Red and Gold Lines: namely, Armour Yards, located near the similarly-named Armour Yard.
The Gold Line runs above ground, at grade and below ground in various portions of its route. It begins at the northeastern terminus, Doraville station in Doraville. The nonrevenue tracks extend northeastward from the station north of I-285. It then goes southwestward paralleling Peachtree Road in DeKalb County. Upon entering Atlanta in Buckhead, it crosses over the Red Line in the median of GA 400 before joining the Red Line, going southwest paralleling I-85. It turns south through Midtown and enters downtown Atlanta, where it meets the Blue and Green Lines at Five Points station. Leaving downtown, the Gold Line continues south, paralleling Lee Street and Main Street into East Point and College Park before reaching its terminus at the Airport station.
