There's a video on YouTube put out by BART regarding recycle the legacy fleet. It's kinda weird though how they specifically say they can't be used for housing based on the fact the lightweight aluminum "cannot be stacked" which seems to ignore the possibility they could be used as a structure for people use of some sort as long as they are a single level i.e. a cabin or studio or something. On a related note, it kills me that the MTA in New York seems to be hostile to the notion of selling retired cars to the general public for creative reuse. They seem to be content with saving a handful for museum use and seeing the rest sunk to the ocean floor or sold for scrap. I've dreamed of turning one of these beauties into a design studio/workshop or getaway cabin:

Can you imagine coming upon one of these in the forest?
