Metropolitan Atlanta Rapid Transit Authority

Beginnings

MARTA was proposed as a rapid transit agency for DeKalb, Fulton, Clayton, Gwinnett, and Cobb counties. These were the five original counties in the Atlanta metropolitan area, and to this day are the five largest counties in the region and state. MARTA was formed by an act of the Georgia General Assembly in 1965. In the same year, four of the five metropolitan area counties (Clayton, DeKalb, Fulton, and Gwinnett) and the City of Atlanta passed a referendum authorizing participation in the system, but the referendum failed in Cobb.

Although a 1968 referendum to fund MARTA failed, in 1971, voters in Fulton and DeKalb counties successfully passed a 1% sales tax increase to pay for MARTA operations, while Clayton and Gwinnett counties overwhelmingly rejected the tax in the referendum.^[4] Gwinnett County remains outside of the MARTA system. In November 2014, however, Clayton County voters passed a 1% sales tax to join the MARTA system, reversing its 1971 decision.^[5]

Also in 1971, the agency agreed to purchase the existing, bus-only Atlanta Transit Company; the sale of the company closed on February 17, 1972, giving the agency control over all public transit in the immediate Atlanta area.^[6]

Heavy rail system

Construction began on MARTA's heavy rail system in 1975, with the first rail service commencing on June 30, 1979.^[6] The system has since built most of the proposed rail lines, as well as stations in Dunwoody, Sandy Springs, and North Springs, which were not included in the original plan. The missing rail segments from the original plan include a Tucker-North DeKalb line with service to Emory University and North Druid Hills, a Northwest line with service to Brookwood and Northside Drive, the extension of the West line to Brownlee-Boulder Park near Fairburn Road, the extension of the Proctor Creek line to West Highlands, and a branch off the south line to Hapeville and Clayton County.^[7]

Georgia State University was contracted to undergo archaeological excavations of rail construction areas in the late 1970s with the MARTA Archeology Project. Artifacts from the excavations are still housed at GSU.^[8]

In December 2000, MARTA opened the final three MARTA rail stations to be built, Dunwoody, Sandy Springs and North Springs - all north of the Interstate 285 Perimeter.^[9] The tracks to those stations were run on the surface of the median strip of Georgia 400, which was constructed just east of the Buckhead area as a tollway during the early 1990s. This is one of just two places at which the MARTA rail system extends outside of Interstate 285. The other is at the Indian Creek Station in eastern DeKalb County.

Since 2000, there have been no active railway expansion projects in the MARTA system due to lack of additional sales-tax funding, the need to spend its limited capital budget on refurbishing its older rolling stock, replacing the fare-collection system, repairing the tracks and their electrical systems, and other long-term maintenance, repair, and operations requirements.

Memorial Drive BRT

On September 27, 2010, MARTA opened a bus rapid transit line along Memorial Drive from Kensington Station to the Goldsmith Road MARTA park and ride lot in Stone Mountain and Ponce De Leon Avenue. The bus had two routes: The Q Express runs between MARTA's Kensington Station and a free 150-car Park-and-Ride lot at Goldsmith Road & Memorial Drive; The Express only stops twice along the way at North Hairston Road and again at Georgia Perimeter College.

The Q Limited also ran north along Memorial Drive from Kensington Station but branched off at North Hairston Road on the way to East Ponce de Leon Avenue. The Q Limited had four stops along the way in addition the same stops for the Express The implementation of revenue-collecting service had initially been planned for early 2009.^[10] Due to low ridership, BRT service was discontinued.

Expansion to Clayton County

On July 5, 2014, the Clayton County Board of Commissioners, by a margin of 3-1 (Jeff Turner, Shana Rooks, and Sonna Gregory voting in favor,) approved a contract with MARTA to extend service to the county, financed by a 1 percent sales tax. Fulton and DeKalb county leaders approved the expansion. On November 4, 2014, Clayton County residents approved the 1% sales tax to join MARTA. Bus service was implemented on March 21, 2015. The contract also includes provisions for future rail transit to the county by 2025.^[11]

In 2018, commuter rail was selected as the locally preferred alternative of transit mode along the Clayton county corridor, with plans to construct a line from East Point station to Jonesboro and Lovejoy.^[12][13] Those plans fell apart after the Norfolk Southern Railway said it would not allow MARTA to use its track.^[14]

Expansion to Gwinnett County

In September 2018, MARTA's board of directors and the Gwinnett County Board of Commissioners gave conditional approval to an agreement that would see MARTA assume, and significantly expand, operations of Gwinnett's bus system (in operation since 2001) and clear the way for the long-sought-after extension of MARTA's rail system into the county from its current terminus at Doraville. The population of Gwinnett County has significantly increased, and become more racially and ethnically diverse, since 1990, the last time the county rejected joining MARTA. Whereas white business elites were the initial demographic to support the MARTA in 1965, most black voters had voted to fund transit. Large communities of rural white Georgians opposed MARTA.^[15]

The original plan in 2018 includes a detailed multi-year plan to expand heavy rail rapid transit in Gwinnett County. Some aspects of the Connect Gwinnett plan will include a train that runs every ten minutes, and also get more buses to take people to the MARTA station. This was possible because Georgia Legislature permitted counties to raise taxes to fund transit, which before was not allowed.^[16] The contract with MARTA would go into effect only if a public vote, that was scheduled for March 19, 2019, succeeded. The agreement called for a new one-cent sales tax that would be collected in Gwinnett County until 2057.^[17] On March 19, 2019, the third transit referendum failed, with 54.32% of the vote being "No" to expand.^[18] A fourth transit referendum was added to the ballot during the 2020 presidential election, which failed by a margin of slightly more than 1,000 voters as 50.13% of voters chose to vote against the referendum.^[19]

More MARTA program

In November 2016, 71% of Atlanta voters approved a half-penny sales tax increase to fund "More MARTA" projects, projected to raise $2.7 billion over 40 years, in order to significantly expand MARTA by constructing additional bus rapid transit and light rail lines, and multiple and infill stations.^{[20][21][22][23]} In October 2018, MARTA's board approved and allocated funding towards a comprehensive list of "More MARTA" projects, including 29 miles of light rail transit (LRT), 13 miles of bus rapid transit (BRT), arterial rapid transit (ART), transit centers and 15 MARTA stations:^[24][25][26]

1. Beltline Northeast LRT
2. Beltline Northwest LRT
3. Beltline Southwest LRT
4. Beltline Southeast LRT
5. Campbellton Rd LRT
6. Clifton Corridor LRT
7. Atlanta Streetcar Downtown East Extension
8. Atlanta Streetcar Downtown West Extension
9. Capitol Ave BRT
10. North Ave-Hollowell Parkway BRT
11. Northside Drive BRT
12. Peachtree Road BRT
13. Cleveland Ave ART
14. Metropolitan Parkway ART
15. Greenbriar Transit Center
16. Moores Mill Transit Center

In March 2023, MARTA significantly scaled back its list of projects prioritized for delivery by 2028, to six transit lines and the renovation and construction of 3 transit stations.^[24] Among those prioritized projects included the Summerhill, Campbellton, and Clifton Corridor BRTs, the Atlanta Streetcar Downtown East Extension to Ponce City Market, reconstruction of Five Points station, and a platform extension at Bankhead station.^[24] Other projects, including Beltline LRT at other corridors, transit centers, and the Streetcar Downtown West Extension, were deprioritized.^[24] In response to the announcement, the Atlanta City Council unanimously approved an independent audit of More MARTA's program revenues and expenditures.^[27] MARTA has been criticized for slow progress on its More MARTA expansion, rising costs, and ongoing delays.^[3]

In June 2023, MARTA selected a designer to extend the Atlanta Streetcar to the Beltline.^[28] Construction of the $230 million extension was set to begin in 2025.^[29][30] In March 2025, Atlanta mayor Andre Dickens withdrew his support from the Streetcar East Extension, and reprioritized a streetcar extension into the Southside corridor instead.^[31][32] Various lobbying groups, including Better Atlanta Transit had lobbied against this extension, while advocates of Beltline transit, including Beltline Rail Now criticized the late-breaking decision.^[32][31]

In March 2024, Mayor Andre Dickens announced that four new infill stations would be constructed across the network, including at Murphy Crossing – intersecting with the Beltline – as well as at Krog Street, Joseph E. Boone, and Armour Yards.^[33][34]

In June 2024, MARTA began construction on the Summerhill BRT, MARTA's first new transit line in 2 decades and Atlanta's first BRT line.^[35] The $91 million project was projected to be complete in spring 2025.^[35] The 5-mile (8-kilometer) line will run from downtown Atlanta, through Summerhill, and end at the Atlanta Beltline. The line, named the "MARTA Rapid A Line", will utilize new 60 ft (18 m) articulated electric buses. In April 2025, completion of construction was delayed to 2026, due to construction issues.^[36]

In July 2024, MARTA paused a $230 million renovation project of Five Points station, due to opposition from the Atlanta City Council and mayor, due to the project's impact to pedestrians and bus service.^[37] In April 2025, MARTA announced plans to resume the renovation project in preparation for the 2026 World Cup.^[38]

In August 2024, a city audit found that $70 million of the More MARTA capital fund intended for capital projects, had been siphoned to cover MARTA operational expenses.^[39] The audit also found that the sales tax had raised $493 million in More MARTA funding from fiscal years 2017 to 2023, while $69 million had been spent during that time period.^[40] In March 2025, MARTA disputed the audit findings, citing that another audit that found MARTA owed only $865,000 to the More MARTA capital fund.^[41]

Subway/metro

MARTA's rapid transit system has 47.6 miles (76.6 km) of route^{[citation needed]} and 38 rail stations located on four lines: the Red Line (prior to October 2009, known as the North-South Line), Gold Line (former Northeast-South Line), Blue Line (former East-West Line), and Green Line (former Proctor Creek Line).^[44][45] The tracks for this system are a combination of elevated, ground-level, and subway tracks.

The deepest station in the MARTA system is the Peachtree Center station, which is located in a hard-rock tunnel, 120 feet (37 m) beneath the city, where the highest hills in Atlanta are 1,100 feet (340 m) above sea level. No tunnel lining was installed in this station, or the adjacent tunnels. The architects and civil engineers decided to leave these with their rugged gneiss rock walls. The highest station in the MARTA system is the King Memorial station. It rises 90 feet (27 m) over a former CSX rail yard.^{[citation needed]}

MARTA switched to a color-based identification system in October 2009. Formerly, the lines were named based upon their terminal stations or by their compass direction. During the transition between the two naming systems, all stations on the Red and Gold lines used their original orange signs, and all stations on the Blue and Green lines used their original blue signs.

All rapid transit lines have an ultimate nexus at Five Points station, located in downtown Atlanta.^[45] 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.^[45]

Streetcar

The Atlanta Streetcar is a modern streetcar route that is powered by an overhead line and operates in mixed vehicle traffic. The system was constructed by the City of Atlanta and was integrated into MARTA operations on July 1, 2018.^[46][47] The streetcar operates on a 2.7-mile (4.3 km) pinched loop system in Downtown Atlanta.

The Atlanta Streetcar system uses Siemens S70 light rail vehicles.^[48] A total of four S70 cars were purchased^[49] and were built at two different facilities; the cars themselves were built in Sacramento, California while most other major components, like the propulsion system, were assembled at a plant about 30 miles (48 km) north of Atlanta, in Alpharetta.^[50][51] They were delivered in the first months of 2014 and are numbered 1001–1004.^[52]

Buses

MARTA's bus system serves a wider area than the rail system, serving areas in Fulton, Clayton and DeKalb counties such as the cities of Roswell and Alpharetta in North Fulton, along with South DeKalb. As of 2010^[update], MARTA has 554 diesel and compressed natural gas buses that covers over 110 bus routes, operating 25.9 million annual vehicle miles (41.7 million kilometers).^[44] MARTA has one bus route providing limited service in Cobb County (Route 12 has been extended to Cobb County's Cumberland Boulevard Transfer Center).^[53][54] In June 2016, MARTA purchased 18 articulated New Flyer Xcelsior buses, which are primarily used on route 39 Buford Highway, the busiest bus route in the system. All of the MARTA bus lines, except for routes 142, 197 and 198, feed into or intersect MARTA rail lines as well. MARTA shuttle service is available to Six Flags Over Georgia during the park's summer season.

In addition to the free parking adjacent to many rail stations, MARTA also operates five park and ride lots serviced only by bus routes (Windward Parkway, Mansell Road, Stone Mountain, Barge Road, and South Fulton).^[55]

Paratransit

In compliance with the Americans with Disabilities Act (ADA), MARTA provides the Mobility paratransit service for those persons defined as disabled by the ADA. MARTA uses 211 special lift-equipped vehicles for this service,^[44] and can either deliver passengers to their final destination (curb-to-curb service) or can deliver the passenger to the closest accessible bus stop or rail station (feeder service). Mobility is limited to existing rail and bus routes and cannot extend more than a 0.75-mile (1.2 km) radius from any existing route. Mobility service is only provided during the hours of the fixed route servicing the area. An application for acceptance into the Mobility service is required; reservations are required for each trip. In fiscal year 2006, MARTA provided 289,258 Mobility trips.^[56]

A 2001 federal civil lawsuit, Martin v. Metropolitan Atlanta Rapid Transit Authority, was brought by several disabled riders who alleged MARTA was violating the ADA by failing to provide: bus schedule and route information in an accessible format, buses with working wheelchair lifts, stop announcements on rail and bus routes, and adequate staff to schedule and provide on-time Mobility service. The district court ruled in 2002 that MARTA had violated the ADA and granted the plaintiffs an injunction requiring MARTA to improve service to the disabled.^[57]

Microtransit

MARTA has a microtransit system called MARTA Reach that provides on-demand shuttle service from different underserved areas to train stations and bus stops using a mobile app. The system was initially piloted in 2022 using an app built in partnership with Georgia Tech.^[58] It was implemented in March 2026.^[59]

Hours of operation

MARTA operates every day. Rail service is provided from approximately 4:45 am to 1:00 am, Monday to Friday, and 6:00 am to 1:00 am on Saturday, Sunday & most holidays. During certain events (New Year's Eve) trains run until 2:00 a.m. (Trains also run all night during winter storms, though not in passenger service, to prevent ice from forming on non-underground lines.) On weekdays, trains run every 20 minutes on all rail lines from the beginning of service until 6:00 am. From 6:00 am-9:00 am and 3:00 pm-7:00 pm, trains run every 10 minutes on all rail lines. From 9:00 am-3:00 pm and 7:00 pm-8:30 pm, trains run every 12 minutes on all rail lines. From 8:30 pm until the end of service, trains run every 20 minutes on all rail lines. MARTA's Red Line rail service only operates between North Springs and Lindbergh Center stations after 8:30 pm. MARTA's Green Line rail service only operates between Bankhead and Vine City stations after 8:30 pm; Monday-Friday (with the exception of public holidays and track work performed by the authority). On weekends and public holidays, trains run every 20 minutes on all rail lines. Bus routes have varying frequencies dependent upon passenger demand.^[65]

Sales tax

In addition to fare collections, the MARTA budget is funded by a 1% sales tax in Fulton, Clayton and DeKalb counties along with limited federal money. In 2017, the City of Atlanta raised their sales tax for MARTA to 1.5% to improve and expand MARTA. By law, funds from the 1% sales tax must be split evenly between MARTA's operational and capital expenditure budgets. This restriction does not apply to other sources of revenue, including passenger revenue.^[66] The split was written into MARTA legislation at MARTA's formation with the rationale that MARTA should continue expanding and investing in the system. Nonetheless, MARTA has no active heavy rail construction projects. Capital funds continue to decrease every year, creating a shortfall. The operations funds limit the amount of service MARTA provides. The sales tax law was amended by the state legislature in 2002 to allow a temporary three-year 45% capital/55% operations split.^[67] This additional 5% for operations expired in 2005. A 2005 bill to renew the split was tabled by the legislature's MARTA Oversight Committee, forcing MARTA to pass a new budget with cuts in service. The temporary 45%/55% capital/operations split was renewed again in the 2006 state legislative session. The capital funds surplus has resulted in projects, such as a new US$100 million Breeze Card fare collection system and US$1.1 million automatic toilets in the MARTA Five Points station, occurring at the same time that MARTA is struggling to pay for bus and rail operations. In 2015, the Georgia General Assembly approved a new bill that no longer requires MARTA to split the 1% Sales Tax.

The current 1% sales tax was set to be reduced to 0.5% in 2032. In early 2007 MARTA made a request to the City of Atlanta, DeKalb County, and Fulton County to seek a 15-year extension of the 1% sales tax from 2032 to 2047, with a 0.5% sales tax from 2047 to 2057.^[68] This is the fourth time in its history that MARTA sought the extension, the most recent in 1990.^[69] MARTA said the commitment to the tax is needed for the agency to secure long-term financing in the form of bonds to pay for any future expansions to the system.^[68] The resolution called for four new routes: bus rapid transit from H.E. Holmes station to Fulton Industrial Boulevard, bus rapid transit from Garnett station to Stonecrest Mall, transit for the Beltline, and a direct transit link from Lindbergh Center to Emory University (formerly called the "C-Loop").^[70] To approve the tax extension, two of the three government agencies needed to agree to the extension. In March 2007 the City of Atlanta voted 12–1 to approve the extension.^[68] In April 2007 the DeKalb County Commission also approved the sales tax extension.^[71] Some Fulton county officials opposed the sales tax extension on the basis that the proposed service expansions did not include previously proposed expansion of the North Rail line to Roswell and Alpharetta in North Fulton County.^[72]

State funding controversy

MARTA was formed through the Metropolitan Atlanta Rapid Transit Authority Act of 1965, an act of the Georgia General Assembly. In addition to allowing the formation of the agency, and the collection of revenue from taxes, the legislation previously placed restrictions on how the agency managed its funds. In particular, the legislation established that any funds raised from the sale of bonds and capital goods would be spent on capital expenditures, and that any extra proceeds be put aside for paying off bond debt. While the enabling legislation put restrictions on how MARTA could manage its money, MARTA has never received any operational funding from the State of Georgia, making it the largest public transportation agency in the United States and the second-largest transit agency in Anglo-America (after the Toronto Transit Commission)^{[citation needed]} not to receive state or provincial funding for operational expenses.^[73] The funding restrictions on MARTA were removed in 2015, with the passage of House Bill 213 by the General Assembly.^[74]

In early April 2009, MARTA experienced a budget crisis when the Georgia General Assembly failed to pass a bill that would allow MARTA to access its own capital reserve account, in order to compensate for a severe drop in sales-tax revenue during the late-2000s recession. MARTA stated that this could force the agency to discontinue operations one day out of the week, possibly a weekday. The agency's budget crisis forced MARTA to lay off 700 employees. Service cuts and other budget-stabilizing measures began in fiscal year 2011, with the first affected service mark-up in September 2010. Governor Sonny Perdue refused to call a special session as requested, and did not issue an executive order as he stated it would not be legal to do so.

Lack of regional financial support

Since the formation of MARTA, the Georgia state government has never contributed to MARTA operational funding. Currently, MARTA is the largest mass transportation system in the United States not to receive state funding.^[73] Revenue from the Georgia motor fuel tax is currently restricted to roads and bridges and cannot be used for public transportation, further complicating potential sources of state funding for MARTA.^[5] In addition, the other largest two suburban counties (Gwinnett and Cobb counties) have refused to join or fund MARTA. Both Gwinnett and Clayton counties initially agreed to join MARTA but refused MARTA rail and bus service when voters in their respective counties voted against paying to help fund the system. Clayton County finally joined MARTA in November 2014. Gwinnett, along with Cobb County, created independent bus transit: Cobb Community Transit on July 10, 1989,^[93] Gwinnett County Transit on November 5, 2001.^[94] A separate regional bus transit service, Xpress, is operated by the Georgia Regional Transportation Authority in partnership with 11 metro Atlanta counties including Fulton and DeKalb, and began service on June 6, 2004.^[95]

The MARTA Board members are criticized for not being regular users of MARTA and thus are not actually aware of the concerns of MARTA commuters.^[96] Former CEO, Keith Parker, was known for commuting daily from Dunwoody to the headquarters using the Red Line.

Due to no funding from the state of Georgia and its limited funding from Fulton, Clayton and DeKalb counties, MARTA has struggled for many years to provide adequate service to the metropolitan area. As a result, MARTA has gained a notorious reputation throughout the metro Atlanta area for being ineffective and inconvenient.^[73] Many people who own cars avoid using the system altogether while residents in suburban areas usually drive their car to a MARTA rail station (instead of using bus service) if their job is near an adjacent one. MARTA's financial structure (being tied to a 1% sales tax) has forced the agency to cut services during times of economic depression, further resulting in complaints about the inconvenience and inadequacy of MARTA services.^[73]

Although surrounding counties do not pay for MARTA, many of their residents use MARTA by driving directly to a MARTA station or by using a county or regional bus system that connects to MARTA. A license plate study from 1988 to 1997 showed that 44% of the cars parked in MARTA park-and-ride lots were from outside of Fulton and DeKalb counties.^[5] Current fare reciprocity agreements also allow non-paying counties to provide bus service for their residents that provide free connections to MARTA (see Fare reciprocity). According to a 2000 MARTA ridership study, 12% of MARTA riders live outside of MARTA's service area.^[94]

Effects of race on expansion and funding

It is often argued that racial politics also play a role in the operation and future service planning for MARTA. Opponents of Georgia's transportation policies have alleged a race-based two-tiered system, where billions are spent by the state on highway expansion to aid the automobile commutes of mostly white residents of the suburbs and rural areas, while service cuts at MARTA have hurt mostly black riders in low-income areas where residents cannot afford automobile ownership.^[73] Proponents contest that a portion of state funding for highways comes from the gasoline tax, a user fee analogous to the fare MARTA riders pay. Supporters of MARTA have alleged that the lack of participation by other metro Atlanta counties is rooted in racism and classism.^{[73][97][98][99]} In 1987, David Chesnut, then chairman of MARTA, stated, "The development of a regional transit system in the Atlanta area is being held hostage to race, and I think it's high time we admitted it and talked about it."^[100] As part of its Title VI plan, MARTA data revealed that in 2015, 75% of MARTA riders were black.^[101] The percentage of white riders is particularly low outside rush hours.^[97][102]

Criminal activity

Despite a strong safety record, throughout MARTA's history there have been continued concerns regarding criminal activity on MARTA trains and in and around MARTA train stations. In the aftermath of a 1985 aggravated assault against the daughter of a Georgia State University professor, complaints were made that MARTA was underreporting its annual crime statistics. A 1986 review of the previous year's records by MARTA's audit office and the state legislature's MARTA Oversight Committee (MARTOC) showed no deliberate underreporting of crime, but rather over-reporting of crime because MARTA included crimes not related to the rail line and did not adhere to the Uniform Crime Reporting system (reporting multiple crimes by the same person instead of only the most serious crime).^[103]

According to Federal Transit Administration records, MARTA's crime statistics are in line with those of similar-sized systems, such as Bay Area Rapid Transit in the San Francisco Bay area.^[104] Nonetheless, high-profile crimes on or near MARTA have created the impression with some that MARTA is unsafe and lacks a strong police presence, even though it has its own police department.^[104] From 2005 to 2009, two homicides and one rape were reported on MARTA property. The most common crime reported was larceny. The most common area for crime was MARTA's rail service, followed by MARTA's parking lots. For fiscal year 2009, MARTA had a crime rate of 3.09 per 1 million riders, with 483 crimes reported during the entire year.^[105]

Suburban counties have opposed expanding MARTA on the basis that it would lead to increased crime, as well as the cost of expansion and the lack of perceived necessity to areas currently outside MARTA transit. It is alleged that because MARTA's service area includes some of Atlanta's most economically depressed and high-crime neighborhoods, expansion of MARTA would supposedly allow crime to spread to suburban areas. Then-MARTA-CEO, Beverly A. Scott, acknowledged that assumption and cites a study that did not find transit systems to nucleate crime.^{[citation needed]} Other counterarguments often cite the case of the Washington Metro, which provides services in economically depressed areas with limited problems in suburban Washington D.C. stops.^[106]

Reliability of service

As is typical of rail transit in the United States, MARTA's rail lines have two parallel tracks. Any train failure or track work results in shared use of the other track by trains going opposite directions, a situation known as single-tracking.^[107] There are no plans at this time to expand the number of tracks. MARTA is currently nearing the end of a complete replacement of tracks on all rail lines. Over the past few years, this replacement work has caused the agency to implement single-tracking on the weekends, which in turn has caused weekend patrons to experience less-frequent service.^[108]

In the summer of 2006, as a result of unusually high summertime temperatures, many MARTA rail cars became overheated, damaging on-board propulsion equipment. As a result, many trains broke down and had to be taken out of service for repair. This was further compounded by the fact that at any given time up to 50 older rail cars were out of service as part of MARTA's rail car rehabilitation project. To compensate for the reduced number of operating rail cars, MARTA shortened trains from six to four cars in length. This sometimes resulted in almost half of the trains being shortened, creating crowded conditions for passengers.^[109]

A 2024 analysis found that MARTA's rail lines had experienced a significant surge in weekend service cuts and delays due to single tracking, resulting in 5,500 canceled trains in 2023.^[110][111] This was especially problematic on the Gold and Red Lines, which were single-tracked 80% of weekends, while the Blue and Green Lines were single-tracked 50% of weekends.^[111]

Misuse of funds by employees for personal expenses

In 2006 internal and external audits of MARTA corporate spending revealed personal charges on a pair of MARTA credit cards used by former General Manager and CEO Nathaniel Ford and two of his secretaries.^[112] Ford's charges included $454 at a golf pro shop, $335 in clothing from Men's Wearhouse and a $58 visit to the dentist.^[112] In response to the 2006 audit, Ford sent MARTA a check for $1,000 as reimbursement for the charges.^[112] An additional credit card with charges involving two of his secretaries, Iris Anthony and Stephannie Smart, was also uncovered. Smart used the cards to pay approximately $6,000 in private expenses, and subsequently agreed to repay this amount to MARTA.^[112]

Clifton Corridor

Rapid transit alternatives are as of October 2011, under consideration for the Clifton Corridor, from Lindbergh Center, following the CSX rail corridor to Emory University and the Centers for Disease Control, with possible continuation along the northern edge of Decatur on to Avondale MARTA station. Bus, light rail and heavy rail rapid-transit options had been considered,^[115] with light rail being selected as the preferred option.^[116]

Mall at Stonecrest Expansion

Eastward expansion focuses on bus rapid transit from downtown Atlanta along I-20 and extension of heavy rail transit from Indian Creek station, south along I-285 to I-20, then east along the I-20 corridor to the Mall at Stonecrest. The current Green Line would also be extended east from its current terminus at Edgewood/Candler Park station to Mall at Stonecrest.^[117] This proposed extension has not been studied further since 2018.

Connect 400

The Georgia 400 Transit Initiative (also known as "Connect 400") is a MARTA project to study options for expanding high-capacity transit along the Georgia State Route 400 corridor into the northern reaches of Fulton county.^[118][119] The initiative, kicked off in December 2011, envisages an 11.9-mile extension of rapid transit service, starting in the south at North Springs Transit Station, the current terminus of the existing MARTA Red Line. From there, such an extension would continue northward through the cities of Sandy Springs, Roswell, and Alpharetta, terminating in the vicinity of Windward Parkway.

As of the fifth public meeting on the subject on September 26, 2013, the study had narrowed the field of transit technology alternatives to three, all using existing right-of-way along SR 400: heavy-rail transit (HRT, extending the Red Line northward), light-rail transit (LRT), or bus rapid transit (BRT). Early designs for all three options include stations near Northridge Road, Holcomb Bridge Road, Mansell Road, North Point Mall, and Windward Parkway; initial sketches of the LRT and BRT options also include a station near Old Milton Parkway.^[120]

As of June 2015,^[121] the project is moving into the Environmental Impact study stage of the planning process. According to MARTA Representatives at the April 2015 meetings, the expansion could open in 2025 at the earliest assuming a best-case scenario. Federal funding is still not approved; the Environmental Impact study must be complete. By the April 2015 meeting, the LRT option has been discarded. The HRT option has been approved as the Locally Preferred Alternative,^[122] though two BRT options exist - one that would run in a dedicated bus guideway and the other to integrate with Georgia DOT's planned work for the corridor. The GDOT integrated option would include sharing normal traffic lanes at least in some parts of the route. The plans for stations at Mansell Rd. and Haynes Bridge Rd. have been merged into one station at North Point Mall.

As of June 2018, the project's adopted alternative is bus rapid transit (BRT) style bus service utilizing express lanes along new toll lanes. Heavy rail expansion will not be considered according to the signed House Bill (HB) 930.

Atlanta Beltline

Additionally, several traffic corridors are currently being studied by MARTA for possible system expansion. The Atlanta Beltline is a proposal for the use of light rail and possibly bus or streetcar service on existing railroad rights-of-way around Atlanta's central business districts.^[123] The conversion of existing rail right-of-way to the proposed Beltline also calls for the creation of three additional MARTA rapid transit stations where existing lines intersect the Beltline at Simpson Road, Hulsey Yard, and Murphy Crossing.

Proposed new infill stations

Adding another station to the existing line near Armour Yard (MARTA's main railyard, opened 2005) has also been discussed, as the Red and Gold MARTA lines, the northeast Beltline light rail, proposed commuter rail lines to points northeast such as Athens (the "Brain Train") and Gainesville, would all pass through Armour Yard. Other stations that have been proposed are; Mechanicsville, Boone, Murphy Crossing, and Krog.

The proposed Atlanta Multimodal Passenger Terminal (MMPT) would be built next to Five Points station, connecting MARTA to surface passenger rail, including commuter rail, future intercity rail, Amtrak, and possible high-speed rail in the Southeast Corridor.

Additional expansion plans for MARTA and other metro Atlanta transportation agencies are detailed in Mobility 2030 a timeline by the Atlanta Regional Commission for improving transit through the year 2030.
