Rio Grande 169

Denver and Rio Grande Western No. 169 is a "Ten Wheeler" type narrow gauge steam locomotive. It is one of twelve similar locomotives built for the Denver and Rio Grande Railroad (D&RGW) by Baldwin Locomotive Works in 1883. It was built as a passenger locomotive, with 46 in drivers, the second largest drivers used on any three-foot gauge D&RGW locomotive (The K-37s have 44 in drivers).

During its operational life it was used on all major narrow gauge D&RGW lines. It appears in two Otto Perry photographs on the branch to Santa Fe, New Mexico in April 1933. It was taken out of service in 1938 and then refurbished in 1939 to appear at the 1939 New York World's Fair. In 1941, the railroad donated it to Alamosa, Colorado and has been on display in Cole Park there since. It was added to the National Register of Historic Places as Denver and Rio Grande Railroad Locomotive No.169 in 2001.
