To my best recollection, these two loco's were used from Rockwood to Silverton by movie company. After the staged head on wreck for the movie "D&RG," they were towed to Durango. Later moving to Alamosa, either dead in a train or loaded on flat cars. Final destination was Pueblo where they were cut up for scrap (arrived Pueblo loaded on std gauge flat cars)
Never used for yard switching.
