Denver & Rio Grande Western No. 346 is a three-foot-gauge 2-8-0 built by Baldwin Locomotive Works in 1881.
It belongs to the early generation of narrow-gauge Consolidations used as the Denver & Rio Grande expanded through Colorado mountain territory.
The locomotive spent decades in Rio Grande service carrying freight and other traffic over routes where narrow gauge reduced construction cost and allowed tighter curves.
In 1936, while on loan to the Colorado & Southern, No. 346 was involved in a runaway wreck on Kenosha Pass.
The locomotive was heavily damaged but was not scrapped.
Chicago, Burlington & Quincy’s Denver shops rebuilt the engine after the wreck, creating a significant repair chapter in the artifact’s physical history.
No. 346 continued operating for the Rio Grande until 1947.
Rail historian and preservationist Robert W. Richardson acquired the locomotive in 1950 and saved it during the period when large amounts of Colorado narrow-gauge equipment were being scrapped.
The locomotive became part of the Colorado Railroad Museum collection and has been restored to operation.
The museum identifies 346 as the oldest operating steam locomotive in Colorado. For TransitSatellite, this claim should remain attributed and time-sensitive, while the deeper story focuses on the original 1881 engine surviving service, wreck, rebuild, retirement, and preservation.
