manager John Harper — senior vice president Cathy Swartz — CFO D&SNG engines As of 2023, the Durango and Silverton Narrow Gauge Railroad appears to operate nineteen locomotives, eight coal-fired and/or converted oil-fired steam engines and nine diesel engines. The current roster goes as follows: Steam Technical information The steam-powered locomotives used today on the Durango and Silverton Narrow Gauge Railroad were built during the 1920s. There are three classes, K-28, K-36 and K-37, which are all based on wheel arrangement and pulling power of the locomotive. As of 2023, of the nine steam locomotives currently owned by the D&SNG, Nos. 473, 476, 480, 481, 482 and 493 are all operational. The K represents the nickname "Mikado" that describes a locomotive with two non-powered, pivoting wheels in front of eight driving wheels, which are connected to driving rods powered by the engine's pistons and finally two non-powered trailer wheels located under the cab. The name comes from the fact that the first significant use of the type was a series built by Baldwin Locomotive Works for the Japanese Railways in 1887. The numbers 28 and 36 designate the tractive effort (pulling force) of the locomotives in thousands of pounds. The tractive effort of K-28s is rated at and the tractive effort of a K-36 is a . The weight of a K-28 with a full tender is and a K-36 weighs with a full tender. 470 series The 470 series, or "K-28" class "Mikado" type locomotives, were ten engines designed for freight service along the D&RG. They were built by the Schenectady Locomotive Works of the American Locomotive Company (ALCO) in Schenectady, New York in 1923. The K-28s have . of tractive effort, superheated, and the boilers are fed by two non-lifting injectors. Air brakes are 6-ET automatic and also feature a straight air secondary braking system for daily passenger trains. Due to their smaller size, these engines are often used on the D&SNG for shorter trains, usually the first or last on the schedule, and often for helper service or sectioned trains. Despite being smaller than the K-36 class locomotives, older and less powerful, the engine crews tend to favor a trip on these engines because the design ALCO used was superior in balance and servicing. Firing can be tricky when the engine is working hard, as the clam shell-style firedoors tend to pull into the backhead of the
