Rio Grande class K-36
The Denver and Rio Grande Western K-36 is a class of ten 3 ft (914 mm) narrow gauge 2-8-2 "Mikado" type steam locomotives 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. Of the original ten, four are owned by the Durango and Silverton Narrow Gauge Railroad (D&SNG) and five by the Cumbres and Toltec Scenic Railroad (C&TSRR). Number 485 fell into the turntable pit at Salida and was scrapped in Pueblo in 1955, with many parts being saved.

The locomotives are of outside-frame design, with the driving wheels placed between the two chassis frames which support the boiler, but with the cylinders, driving rods, counterweights and valve gear on the outside. This general arrangement is shared with the earlier K-27, K-28 and later K-37 Mikado engines.
The locomotives' designation of K-36 comes from two different sources. The K in the designation comes from the locomotives' wheel arrangement (Mikado), and the 36 stands for 36,200 pounds of tractive effort.
The K-36s were used primarily as freight locomotives out of Alamosa to Durango and to Farmington, New Mexico, as well as out of Salida to Gunnison (over Marshall Pass) until 1955 and to Monarch on the Monarch Branch until 1956. 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. They were heavily used during the pipe boom in Farmington and hauled long freight trains between Alamosa and Farmington.
In 1937, three K-36s, Nos. 482, 483 and 489, were equipped with steam heat and signal lines to haul passenger trains like the Shavano and the San Juan Express. Eventually, in 1945, Nos. 484, 485 and 488 were also equipped, too.
As of 2020, eight of these locomotives still operate regularly. Nos. 483, 484, 487, 488 and 489 are owned by the Cumbres and Toltec Scenic Railroad (C&TSRR) and Nos. 480, 481, 482 and 486 are owned by the Durango and Silverton Narrow Gauge Railroad (D&SNG). However, No. 483 is stored out of service at Chama. As of June 2020, No. 489 is temporarily out of service while it undergoes a new smokebox installation during its Federal Railroad Administration (FRA) mandated 1,472-day inspection. However, due to COVID-19, No. 489 is currently expected to return to service later in 2021. On December 15, 2020, the C&TSRR announced that, in addition to the 1,472-day inspection and rebuild, No. 489 is also being converted from burning coal to burning oil. No. 489 will be the first and only so far locomotive on the C&TSRR to be converted to burn oil. No. 489 is currently expected to be back in service again in time for the 2021 operating season, although an exact date is still to be announced. In addition, as of early November 2020, No. 480 is also currently undergoing a conversion from burning coal to burning oil and will be the third and last locomotive so far on the D&SNG to be converted to burn oil, the others being K-37 class No. 493 and K-28 class No. 473.
