The Denver and Rio Grande Western K-36 is a 3 ft (914 mm) narrow gauge 2-8-2 "Mikado" type steam locomotives, of which 10 were made, built for the Denver and Rio Grande Western Railroad (D&RGW) by Baldwin Locomotive Works.

They were shipped to the Rio Grande in 1925 and were first used along the Monarch Branch and Marshall Pass, but were later sent to the Third Division out of Alamosa.

Number 485 fell into the turntable pit at Salida and was scrapped in Pueblo in 1955, with many parts being saved.

The K in the designation comes from the locomotives' wheel arrangement (Mikado), and the 36 stands for 36,200 pounds of tractive effort.

They were built with special valves to allow brake control between locomotives while double-heading and were commonly found between Alamosa, Colorado, and Chama, New Mexico.

482, 483 and 489, were equipped with steam heat and signal lines to haul passenger trains like the Shavano and the San Juan Express.

483 is stored out of service at Chama undergoing a full cosmetic restoration by the Friends of the C&TSRR as of 2023.

489 temporarily went out of service for a new smokebox installation during its Federal Railroad Administration (FRA) mandated 1,472-day boiler inspection.

483 also hauled the last steam powered scheduled passenger train on the Denver and Rio Grande Western Railroad on May 29, 1965.
