Narrow gauge diesel engines have been in use for many years in Durango. Here, diesel engine No. 50 moves the Alamosa passenger car in the Durango rail yard in May 1964. The bridge in the background on the left was the railroad bridge leading out of town to the west for the Rio Grande Southern line. Though still standing after the Rio Grande Southern ended service 12 years earlier, it has long since been removed. The Rio Grande Southern operated between Durango and Ridgway for 60 years. – Ed Horvat for Animas Museum, edhorvat@animasmuseum.org (Catalog Number: 15.33.20 from the La Plata County Historical Society Photo Collections)
