D&RGW 169, Historic steam locomotive in Cole Park, Alamosa, United States.

D&RGW 169 is a steam-powered Ten Wheeler locomotive with four driving axles built in 1883 for narrow gauge railroad service. The machine features about 46-inch diameter driving wheels and weighs roughly 32 tons, making it well suited for passenger train service.

Baldwin Locomotive Works built this 4-6-0 Ten Wheeler in 1883 as one of twelve similar engines for the Denver and Rio Grande Railroad, where it ran on all the major narrow gauge lines. It was taken out of service in 1938, refurbished in 1939 for the New York World's Fair, and donated to Alamosa, Colorado, in 1941.

The locomotive sits in public Cole Park where visitors encounter it as a witness to railroad history in the American West. People stop to photograph the machine and read information panels that explain its role in regional transportation development.

The locomotive stands permanently in Cole Park at Chamber Drive in Alamosa and can be viewed for free. The location is easily walkable and information panels on site explain the mechanical details and history of the machine.

The 1939 refurbishment was not for regular service: the locomotive was prepared to appear at the 1939 New York World's Fair, then retired in 1938 and donated to Alamosa in 1941. It has stood in Cole Park ever since, and was listed on the National Register of Historic Places in 2001 as Denver and Rio Grande Railroad Locomotive No. 169.
