Rob Richardson, noted narrow gauge preservationist, takes a close look at the Rio Grande's Durango to Silverton Branch, the Farmington Branch, the Third Division lines between Salida, Gunnison and Montrose, and the Valley Line between Mears Junction and Alamosa, Colorado.  With 50-year-old photographs and first-hand accounts, Richardson offers the most authoritative chronicle yet on this portion of the Denver and Rio Grande Western's Rocky Mountain narrow gauge railroad empire. *Still in shrinkwrap*
