You guys are bad. I just had to clean my display again. ;-)
So I have yet to have time to go back to the rail yard photos ... But last weekend my uncle handed me his Polaroid SX-70 when I visited him. Arriving home, I found I still had two old, expired packs of Time Zero film and tossed one into the camera. It's badly deteriorated (a decade past expiration!) but still made a couple of images ...

Dreamy, weird stuff. I love it. Here's a slide-show link to the four I posted:

I ordered a bunch of film from The Impossible Project so I'll have fun with this artifact for a time to come.
