I stumbled upon this site, and saw some vintage train photos. There is a pic on the front page to start off, you'll have to click around to find the rest.
Well, I found this link before posting :http://www.tapeshare.com/FultonEl.html
Edit: And this: http://www.tapeshare.com/LIRR.html
I should mention there are a lot of vintage shots and history of East NY which is quite interesting, check it out.
Feel free to move this to the photos section if necessary.
