The entire Uintah Railway, by dangavel, is available on the download station as a WIP. This video shows the "real" section of the line from Mack, CO to Watson, UT. A proposed but unbuilt extension (not in this video) to Bonanza, UT is included in dangavel's route.
dangavel did a fantastic job on this one. For more info you can visit his forum thread: https://forums.auran.com/trainz/showt...
