I remember first reading about this a few years ago and it just seemed like a good idea. New York City's Subway Cars were dumped in the sea off the Delaware cost to create a reef that would allow all sorts of sea life to flourish in what was bascially an underwater desert.
Now 6 years later it's looking like a great idea. More states want the retired cars and Delaware may soon find it a struggle to find new trains for their reef.
There are good pictures, videos and charts from a similar reef off New Jersey's coast here.
