In September 2009 the Cumbres & Toltec Scenic Railroad, in collaboration with the Durango Railroad Historical Society (315), organised a two day special giving a unique view of the 315 work train
on the tracks connecting Antonito (CO) to Chama (NM). A C&TSRR K-36 chase train brought us, the railroad enthusiasts, to the most scenic locations - an unforgettable event!
