The subject of the "2765" was mentioned on another forum, and I posted a picture in response to it. Here's the story...
In 1993 we made some cosmetic changes to NKP 765 to make it look like a C&O Kanawha (pronounced kuh-NAW) which was the C&O's version of a 2-8-4. The two types were essentially identical. We renumbered the engine to "2765" which was a real Kanawha number. There is a chapter in my book about this special year, with a lot of good pictures, like this one by F. J. Ahern.
This was taken on October 23, 1993 on the old C&O in West Virginia. Passing under a classic C&O cantilevered signal bridge, the "2765" is on the point of the New River Train.
