Equipment Information

Lake Superior & Ishpeming 35 is a heavy freight engine built for hauling low-speed ore trains in Michigan’s Upper Peninsula. The Consolidation was the most common wheel arrangement in the history of American steam engines, with more 2-8-0s built than any other one wheel arrangement. LS&I 35 is an unusually heavy example and was designed purely for freight service. It is the only preserved steam engine with a tender booster, a small steam engine that powered the front truck of the tender for additional tractive effort.

COMPARE ME WITH: Louisiana & Arkansas 99, another 2-8-0 Consolidation preserved at IRM. The L&A engine is much smaller than LS&I 35, weighing about 40% less and boasting only half the tractive effort of the large LS&I engine.
