I,m a member of a historic photo website, Shorpy,s. Which has a vast selection of photos from the Civil War era, up to the 1960,s. I was browsing through the other day, and found something that might be useful to someone here, a plant for treating railroad ties.http://www.shorpy.com/node/7900?size=_original
