The Metropolitan Atlanta Rapid Transit Authority (MARTA) recently showed its commitment to environmental conservation and marine habitat restoration by donating two retired subway cars to CRD for use as artificial reefs offshore.

MARTA, the primary public transit agency in metro Atlanta, has long been dedicated to sustainable practices and community engagement, said Richard Thomas, MARTA’s director of sustainability.

“MARTA is thrilled to partner with DNR and be part of the Reef Project,” Thomas said. “Reefing is the most affordable and environmentally responsible way to reuse retired railcars, and we hope to provide more railcars in the future as we make room for the new trains.”

The two retired subway cars, previously serving Atlantans on MARTA’s rail system, have been meticulously prepared and cleaned for their new purpose as artificial reefs. These subway cars will provide essential habitat and substrate for a wide variety of marine species, including fish, coral, and other aquatic organisms. By creating thriving artificial reefs, MARTA aims to contribute to the overall health and biodiversity of Georgia’s coastal waters.

CRD will oversee the deployment of the subway cars, which will be taken by barge to Artificial Reef L, an established reef about two square miles in size, located approximately 23 nautical miles east of Ossabaw Island in about 55 to 65 feet of water.

Over time, the railcars will provide essential marine habitat for sea creatures, including popular sport fish and endangered sea turtles. While the substrate for the reef is man-made, the organisms that will grow on it are entirely natural and beneficial for the environment. Fish and other marine life are likely to investigate the new habitat almost immediately. Corals, sponges, and other encrusting organisms will begin to take hold on the railcars in about one year and will continue to grow and improve the longer they are in the ocean. SCUBA divers and anglers can begin using the reef immediately.

These additions will support ongoing efforts to revitalize and protect the state’s marine ecosystems while providing recreational opportunities for divers and anglers.
“We are incredibly grateful to MARTA for their generous donation,” said Paul Medders, lead of CRD’s Habitat Enhancement and Restoration Unit. “These subway cars will play a crucial role in enhancing marine habitats and fostering a healthier ocean environment. It’s a fantastic example of how public agencies can collaborate to make a positive impact on our environment.”

The deployment of the subway cars as artificial reefs is scheduled for sometime in November, depending on weather and other conditions. Visit CoastalGaDNR.org for updates.
