I stumbled onto a neat collection of pictures and reference info tonight that I wanted to share. I used to find prototype pictures boring. But when it comes to putting a scene together, I'm realizing their value over pictures of models (you never know if a modeler got it "right" or what he might have missed). This site has some of both.

What's nice is a lot of the pictures can be enlarged, and they also have a good amount of old color pictures--those bad, 1950's & 60's color pictures. Don't these almost look like scenes from a layout? Nope. All prototype shot in old color film:





I just spent an hour browsing through these pages.
Have fun!
