Decommissioned MARTA Railcars Developing into Reef Habitats
Last December, the decommissioned railcars were stripped of hazardous materials and inspected by the U.S. Coast Guard before being transported by barge to Artificial Reef L.
In the first dive since the deployment, the DNR Coastal Resources Division witnessed a good amount of soft coral beginning to grow on the railcars and nine species of game fish.

Two Metropolitan Atlanta Rapid Transit Authority (MARTA) railcars deployed into the Atlantic Ocean seven months ago as part of the Georgia Department of Natural Resources (DNR) Reef Project are gradually developing into reef habitats for marine wildlife.
Last December, the decommissioned railcars were stripped of hazardous materials and inspected by the U.S. Coast Guard before being transported by barge to Artificial Reef L, an established reef about two square miles in size, located approximately 23 nautical miles east of Ossabaw Island and deployed in about 55 to 65 feet of water.

Railcar Reef Project Update
In the first dive since the deployment, the DNR Coastal Resources Division witnessed a good amount of soft coral beginning to grow on the railcars and nine species of game fish.
“MARTA is proud to be part of repurposing old railcars in this environmentally responsible way,” said MARTA GM/CEO Collie Greenwood. “It’s exciting to see this type of development on the railcars after only a few months and we hope to provide more retired railcars for reef deployment as we make room for our new trains.”
While the substrate for the reef is manmade, the organisms that grow on it are entirely natural and beneficial for the environment.
Fish and other marine life, such as sea turtles, were likely the first to investigate the railcars when they were deployed.
Corals, sponges, and other encrusting organisms are taking hold now and will continue to grow and improve the longer they are in the ocean.

SCUBA divers and anglers have also been using the reef.
“The artificial reef is looking great, and we are encouraged by the amount of coral growth and marine wildlife activity,” said Cameron Brinton, a marine biologist with DNR’s Coastal Resources Division. “You’ll notice one of the railcar roofs has collapsed, which is typical, and we’ll see more changes to the railcars over time as they become part of the essential marine habitat for sea creatures, including popular sport fish and endangered sea turtles.”

A History of Railcars as Artificial Reefs
MARTA’s railcars join previously deployed materials, including U.S. Army M-60 battle tanks, barges, tugboats, New York City subway cars, and other manmade structures.
Artificial Reef L was first created in 1976 as part of a network of 32 offshore reefs that the Coastal Resources Division has been building and improving for more than 40 years.
Accessibility enhancements at Nevins St Station will be financed through a development agreement tied to the MTA's Zoning for Accessibility initiative.
Approved by the Commonwealth Transportation Board, the program supports ongoing infrastructure projects while providing new investments in transit, state of good repair and transportation alternatives.
Safety improvements funded through a $25 million federal investment are credited with reducing trespassing and train-vehicle collisions along the Brightline Florida corridor.
Weekend rail ridership was especially strong, soaring 18% as riders embraced expanded access to jobs, entertainment, dining, and cultural destinations, said the agency. Total system ridership for May, including bus and rail, was 26,966,657.
Customers traveling between Redlands and Los Angeles can now tap their preferred payment method, including a credit or debit card, mobile wallet, or wearable device, at station validators before boarding and again while exiting.
The budget covers July 1, 2026, through June 30, 2027, a period when pandemic emergency funds run out, the District faces a structural deficit of $375 million, and a regional transit funding measure may appear on the November ballot.
The historic redesign will transform the busiest transit hub in the Western Hemisphere from the tracks to the street level, creating a more efficient, cleaner, and functional experience for more than 600,000 daily commuters and millions of visitors.
New York Governor Kathy Hochul joined leadership from the MTA, elected officials, and Harlem community leaders to break ground on the major construction stage of the transformative Second Avenue Subway Phase 2 project.
The move ensures Caltrain service will continue operating as usual in the near term, but long-term financial challenges remain for the rail agency absent a new revenue source.
