This route would include the Union Pacific route of Cheyenne to Laramie on their Overland route. As well as a few good freight locomotives and passenger locomotives. Such locomotives could include the Union Pacific GTEL third generation , Union Pacific Big Boy steam locomotive , UP 844 , and perhaps include the UP SD90MAC . I will include all the different sources that were used for the following attached images and map of the suggested route: The length of the route would be about 48 miles in between Cheyenne and Laramie. Some services that could be included would be some steam excursion trains with 844 and 4014 along with optional freight service with the steam engines. And for the GTEL and SD90MAC would be freight including intermodal containers, grain cars, coal cars, or refrigerator cars.
