Silverton Railroad No. 100 Steam Locomotive Blueprint - Historical Engineering Diagram #1839189 (License: Personal Use)

This precise engineering blueprint illustrates the Ouray-built steam locomotive No. 100 for the Silverton Railroad Company, featuring multiple orthographic projections-including side, front, rear, and tender views-with labeled components such as the cab, boiler, smokestack, and wheel assemblies. The tender is clearly marked “SILVERTON R.R. CO.” and includes structural details like riveted seams, couplers, and coal/water capacity indicators. The schematic reflects standard narrow-gauge mountain railway design used in Colorado’s San Juan Mountains during the mining boom era.

Used on historical railroad museum websites, archival digital collections, or educational pages about narrow-gauge steam technology; targets railfans, historians, model builders, and researchers seeking primary-source technical documentation of early 20th-century U.S. mountain railroads.
