The Stone Mountain Scenic Railroad (SMRR) is a standard gauge railroad that circles the perimeter of Stone Mountain Park in a loop, and provides views of the mountain en route.

The railroad utilizes what was originally an industrial spur built in 1869 by the Stone Mountain Granite Company to serve quarries at the foot of the Stone Mountain, with a connection to the Georgia Railroad's main line in Stone Mountain Village. The railroad later started an excursion service to the mountain. The spur was later abandoned, leaving the right of way in place (with the rails removed). In 1960, Stone Mountain Scenic Railroad, Inc. was formed to construct a tourist railroad encircling the mountain, operating it under lease from the Stone Mountain Memorial Association (a state-operated association established in 1958 for developing and managing the mountain as a park). Between 1961 and 1963, two miles of former quarry trackage were rebuilt, followed by construction of additional new trackage to complete the road around the perimeter of the mountain. The mileage of the circuit around the mountain is advertised as being 5 miles (8.0 km) long, however, the actual mileage is 3.88 miles (6.24 km).

The Stone Mountain Memorial Association assumed full operation of the railroad in 1981. As the steam locomotives came in need of major repairs, the road opted to withdraw them and operate diesels. In 1987, the spur connecting the mountain trackage to the CSX main line was restored, and the railroad hosted several visiting trains, including Savannah and Atlanta Railway steam locomotive number 750.

In January 1998, the Memorial Association leased operations of the railroad and the other attractions within the park to Herschend Family Entertainment, operators of the Silver Dollar City theme park in Branson, Missouri and the Dollywood theme park in Pigeon Forge, Tennessee.

In 2004, the trackage connecting the railroad to the main line was dismantled and the spur truncated to just before the bridge spanning Robert E. Lee Boulevard within the park's premises. The trackage and decking were removed, though the bridge's girders remain, and the right of way to the west of the bridge was converted to a pedestrian trail, while the railroad continues to use the remaining track to reverse the train's direction. In 2011, major upgrades of the track, passenger cars, and diesel locomotives were performed. The diesel locomotives received new motors and other upgrades, as well as a new paint scheme. The steam locomotives received some cosmetic restoration at this time as well. The railroad had de-accessioned its last remaining steam locomotives in early 2013, and currently owns and operates diesels exclusively.

Stone Mountain originally had three steam locomotives, the "General II," "Texas II," and "Yonah II." The SMRR named the engines after the famous engines of The Great Locomotive Chase, and were given nineteenth century style smokestacks and headlights. Despite these modifications, the engines, having been built between 1919 and 1927, still have noticeably modern appearances, with larger proportions than their ancestors and have more advanced cylinders, valve gear, and other modern applications. While steam engines ceased running in the 1980s, they continued to "pull" trains for some time. In these instances, one of the steam engines was coupled in front of a diesel which, while disguised as a baggage car or auxiliary tender, would push the engine. The diesel's controls were placed in the cab of the engine and air piped from the diesel's main reservoir to allow the steam engine's whistle to sound. Aside from the whistle, the steam locomotive remained inactive, with the diesel being the train's sole motive power.

In the late 1980s and early 90s, the railroad supplemented its GP7 and GP9 diesels with ones inherited from the recently dissolved New Georgia Railway, which have pulled trains regularly since. At that time, the steam engines would only be pushed on special occasions, and no attempt was made to disguise the diesel behind it. The practice of pushing the steam engines ended in 2002, and they remained within the yard until being donated to other tourist railroads or museums, the first leaving the railroad in 2008, followed by the remaining two in 2013.

The Stone Mountain Railroad currently has the following locomotives:

Baggage car/tender 1114	EMD SW1		EMD	1946	Boston and Maine Railroad	Acquired by Stone Mountain in 1973 to assist the steam locomotives on gradients, later fitted with a false baggage car shell when the railroad began to dieselize so as to make the steam locomotive placed in front appear to be pulling the train. Sold in 1995 to become Standridge Color's #3 in Social Circle, GA.
104 General II	4-4-0		Baldwin Locomotive Works	Aug 1919	Red River and Gulf Railroad	Acquired from the Louisiana Eastern Railroad in 1962.

60 Texas II	4-4-0		Baldwin Locomotive Works	May 1922	San Antonio and Aransas Pass Railway	Acquired from the Louisiana Eastern Railroad in 1963. Withdrawn 1983 due to boiler and mechanical issues, though it continued to occasionally "pull" the train while pushed by a diesel until 2002, and remained within the rail yard thereafter. Sold to the Gulf and Ohio Railways in Knoxville, Tennessee in 2012 and moved in March, 2013. Currently undergoing restoration to operating condition for use on the Gulf and Ohio's Three Rivers Rambler tourist train operation.

Placed on display at the Memorial Depot in 1984, engine was donated to the New Hope Valley Railway in Bonsal, North Carolina in 2012, and the engine was moved the following year. The engine is currently on display while funds are being raised for its restoration to operation.
3525 Big Dixie	0-8-0		Baldwin Locomotive Works	Sep 1922	Illinois Central Railroad	Acquired by Stone Mountain in 1967, sold shortly thereafter when its size and short wheelbase proved to be too heavy for the railroad's sixty pound rails at the time. Currently on display at Tanglewood Park in Clemmons, NC.
349	4-4-0		Baldwin Locomotive Works	Jun 1891	Savannah & Western Railroad, Central of Georgia Railway	Never placed in service on the Stone Mountain Scenic.
