This image is a scan from a print that I made back around 1980, by making a 4"x5" copy negative from an old original print, because the original negative was not available.
I learned the name of this railroad after many Google searches, when I found The California Digital Library, and this image of the Willey Brook Bridge P. & O. R.R. Crawford Notch N. H.. I enlarged the image to its highest ability, saved it to my computer, and tweaked it enough so I could read the sign on the engine enough to do another search and finally find the name of the company.
Here is a map of the P.&O. line I found at www.history-map.com.
