I have not, but I have a few other Rio-Grande themed books: "Rocky Mountain Railroads, Volume II" which covers all of the Rio Grande's Narrow Gauge, and my personal favorite, "Chasing Trains" by Bob Richardson, which is essentially his autobiography and covers all of his adventures around the US and the world. A truly incredible read. I also have a record of the AT&SF's entire steam-era engine roster (Iron Horses of the Santa Fe Trail, almost 300 pages with another 400 of diagrams for every class). There are also some more generic railroading and loco diagram books in there too.
Thank you for the kind words. I've been working on it little by little in my free time, and I managed to reskin a few more models today. The revamping is going to be the hard part (As is figuring out how on earth PBR textures work), but hopefully I can get some screenies of my new engines and their route out soon.
