These three are real photo postcards; that is, one-off postcards made by Kodak from negatives sent in by camera owners. The photo of the N&W hopper and the two crew cars can be dated to between 1904 and 1918, as can the shot of the steam locomotive. The one of the crane resetting a CC&O derailment is from the 1918-1930 period. There is no other identifying information on any of these cards. I think they’re fascinating and I snapped them up as soon as I saw them.

Hi Bob, I just wanted to leave you a quick comment. I found your site while researching my family history. I am pretty sure my great grandfather worked on the CC&O. He was from Mitchell County NC and married a woman from Gate City Virginia. Family rumors have it that he was injured in a train accident and while looking for info on that i found this page. Nice work you have done here! I will be back to check out more of your site.
Thank you for your comment. I hope you find out more about your grandfather.
