Lake Superior & Ishpeming No. 22 is a class SC-4 "Consolidation" type 2-8-0 steam locomotive, built at Alco's Pittsburgh, PA, works as #38 in 1910 for the Marquette & Southeastern, which operated a sixty mile line between Big Bay and Lawson, MI.
One year later, the M&SE became the Munising, Marquette & Southeastern. In 1923, when the MM&SE merged with the Lake Superior & Ishpeming, #38 was renumbered #22.
The LS&I was one the last Class I railroads to dieselise in the US, and #22 worked for over fifty years based at Marquette, MI, where ore was delivered to a dock for loading the big Great Lakes ships.
No. 22 was one of twelve LS&I Consolidations sold to the Marquette & Huron Mountain Railroad tourist line in 1963. The Marquette & Huron operated on the recently abandoned LSI Big Bay branch line.
No. 22's last run on the Marquette & Huron was on Labor Day 1965. In 1985, the tourist line ceased operations and its equipment was put up for sale, at which time #22 was bought by the Mid-Continent Railway Museum, where it remains today as a static exhibit.
