Thank you. I do not know of any gondola parts taht were saved. Flat cars had a few uses and stock and box cars were loved by the farmers around Mack, but the mechanical nature of the gondolas did not seem to have much farming apeal. No plans for a third volume, as I donot nearly have much more than cliff notes, scattered data, and a few photos. I can only hope that a wad of Uintah photos become available in the future, but that seems unlikely, plus uintah nuts are much harder to find than RGS nuts, and therefore future sales of said volume would be hard to find.
