Subway Cars...Underwater

First thought upon seeing this: "Oh no, the dolphins!" (Okay, maybe that's slightly exaggerated...I was mostly perplexed as to how this is legal.)

Then I read the accompanying article, and all was made clear: these subway cars are getting second lives as artificial reefs along the Atlantic shore.

Unlike us humans, the fish/corals/assorted sea creatures will never have to experience late or disabled trains, smelly passengers, and sticky seats. Lucky them!
