Denver & Rio Grande Western Railroad San Juan Extension
(Cumbres & Toltec Scenic Railroad)
Antonito to Chama, New Mexico, over Cumbres Pass
National Register 1/16/1973, additional documentation and boundary increase 4/24/2007, National Historic Landmark 10/12/2012, 5AA.664 / 5CN.65
This nationally significant narrow-gauge railroad segment exists as one of only two operating sections of what was once a state wide network of three foot gauge tracks built and operated by the Denver and Rio Grande Railroad. Completed in 1880, the 64-mile line helped to sustain the ranching and logging activities in northern New Mexico and southern Colorado, supplied the oil industry in and around Chama and Farmington, New Mexico, and formed a link for the transportation of precious metals from the San Juan mining camps to Denver. The states of Colorado and New Mexico jointly own and continue to operate the rail segment as a tourist attraction. The property is associated with the Railroads in Colorado, 1858-1948 Multiple Property Submission. (2005 photograph.) More information (PDF, 9.57 MB). National Historic Landmark listing.
Denver & Rio Grande Railroad Antonito Depot
6128 Front St.
State Register 8/31/2006, 5CN.499
The 1880 Denver & Rio Grande Railroad (D&RG) Antonito Depot is an important and distinctive masonry example of a combination-type depot active in the San Luis Valley. The depot served for over sixty years as the junction point for the branch line to Santa Fe, New Mexico, and the D&RG’s San Juan Extension from Alamosa to Durango and Silverton. In addition to providing passenger and express package service, and housing the local office of the Western Union telegraph, the depot also served as the office for railroad freight operations originating or terminating in the Antonito area. The depot was the western-most station on the Rio Grande’s San Juan Extension accommodating both standard and narrow gauge trains. More information (PDF, 2.43 MB).
Denver & Rio Grande Western Railroad Engine 463
US Hwy. 285 (Cumbres & Toltec Scenic Railroad)
National Register 5/12/1975, 5CN.68
Built in 1903 by the Baldwin Locomotive Works of Philadelphia, Engine No. 463 is one of only two remaining locomotives of the K-27 series originally built for and operated by the Denver & Rio Grande Western Railroad. The K-27 series was a departure from the design most prevalent on Colorado’s narrow gauge lines, resulting in a locomotive with one and one-half times more power. The arrival of this series marked a significant turning point in the operation of the D&RGW’s narrow gauge lines that was to remain in effect until the end of Class I narrow gauge steam locomotion in 1968. The Friends of the Cumbres & Toltec Scenic Railroad restored the engine to operating condition.

SPMDTU Concilio Superior
603 Main St.
National Register 3/29/2001, 5CN.817
As the headquarters for La Sociedad Proteccion Mutua de Trabajadores Unidos since 1925, the building represents an important aspect of Hispano history. Originally created to combat racism against Hispanos in the San Luis Valley, this fraternal organization later expanded to provide mutual aid, thereby playing an important role in the overall social history of Colorado. Construction of this building popularized the use of steel trusses, introduced changes in massing, and promoted hybridized Southwest vernacular designs subsequently utilized in other Hispano enclaves.
