Phillip,
fortunately with the Flickr, assuming you have an a/c one can leave comments and tags so noted identification is possible. Just where did you see the C&S in relation to the others groups I mentioned?
I went through from end to end last night and must have missed them obviously. There seemed to be many duplicates and flopped images that were plain as day and Eastern US sg steam just doesn't do it for me.
Elsewhere in the Barringer Library photostream is heaps on the D&RGW as has been posted before.
