Union Pacific 618 is a class "C-57" 2-8-0 "Consolidation" type steam locomotive previously owned by the Union Pacific Railroad. The engine is now located in Heber City, Utah and owned by the Heber Valley Railroad. Built in July 1907 by the Baldwin Locomotive Works (BLW) of Eddystone, Pennsylvania, No. 618 is one of 12 surviving C-57 Series locomotives. The locomotive operated in revenue service until 1958. It was then donated to the State of Utah, where it sat on display for many years. In the mid 1960s, a full restoration effort began on the locomotive with the promise of heading up Utah's first tourist railroad in Heber City after the state donated the engine to the National Railway Historical Society. Today, it is one of UP's oldest locomotives and the first steam locomotive to be removed from a Public Park, and put back into operational condition in excursion service. The engine currently is out of service in Heber City, Utah undergoing restoration back to operating condition.
