There's something endlessly fascinating about subway cars retiring in the deep seas and transforming into artificial reefs. The MTA's fleet of Redbird cars have been underwater since 2001, in New Jersey, Delaware, Maryland, Virginia, South Carolina and Georgia. Coming up next Monday Bob Martore, the Artificial Reef Manager from South Carolina’s Department of Natural Resources, will be in town to explain how subway cars help provide homes for marine life (tickets), and the organizers of the event just sent us over this video of a sea turtle and some of his friends taking the 7 train! (Warning: watching this video leaves you at risk of having that song from The Little Mermaid stuck in your head all day.)

We're told the reef program continues (even though subway cars were reportedly falling apart underwater in New Jersey), but has slowed down—Georgia just received 44 cars in January.
