Grand Canyon Railway 29 is an SC-3 class 2-8-0 "Consolidation" type steam locomotive, built by the American Locomotive Company's (ALCO) Pittsburg Works in May 1906 for the Lake Superior and Ishpeming Railroad (LS&I) in Upper Michigan. The sole member of the LS&I's SC-3 class, it was originally numbered 14, but was renumbered to 29 in 1924. Having gone through two major rebuilds to upgrade its performance, No. 29 served the LS&I in pulling freight and iron ore trains until being retired in 1956.

In 1963, No. 29 was sold to the Marquette and Huron Mountain tourist railroad, where it spent several years in storage alongside other LS&I steam locomotives. In 1985, No. 29 was sold to a private owner, who in turn sold it to the Grand Canyon Railway (GCR). GCR returned No. 29 to service in April 1990, and the locomotive pulled the railway's passenger trains between Williams, Arizona and the South Rim of the Grand Canyon. As of 2026, No. 29 is out of service, undergoing a boiler inspection.
