Denver & Rio Grande Western No. 488 is one of the surviving K-36 2-8-2 locomotives built by Baldwin in 1925.
The locomotive was designed during the Rio Grande’s final major period of narrow-gauge modernization.
Compared with older narrow-gauge engines, the K-36 offered enough tractive effort and boiler capacity to move substantially heavier trains.
No. 488 served in the same mountain railroad system where tunnels, steep grades, tight curvature, and high elevation placed unusual demands on locomotive crews and machinery.
The decline of mining traffic and competition from highways progressively reduced the narrow-gauge network after World War II.
Preservation of the Cumbres & Toltec segment in 1970 prevented No. 488 and related equipment from becoming disconnected museum artifacts.
The locomotive remains part of C&TS’s operating steam roster.
No. 488 is coal fired, retaining the traditional fuel system used by the class during D&RGW service.
Its modern passenger assignments differ from much of its original freight work, even though the underlying route and locomotive technology are historically continuous.
For TransitSatellite, the page should avoid using modern tourist operation as if it exactly recreates a 1930s freight day. Preservation is historically grounded but has different train consists, regulations, staffing, and economic purpose.
