Lake Superior & Ishpeming No. 23 is a class SC-4 2-8-0 Consolidation type steam locomotive. It was built by Alco in 1910 for the Lake Superior & Ishpeming Railroad.
It spent most of its career working iron ore trains to and from the mines of Michigan's Upper Peninsula.
It was sold to the Marquette & Huron Mountain Railroad, a tourist railroad, in July 1963 where it hauled passenger trains, and the occasional freight.
It is now at the Empire State Railway Museum, located in their car barn in Phoenicia, NY, where it is undergoing cosmetic restoration.
