Boise Train Depot
Big Mike, a Mikado-type steam locomotive, was built in 1920 by the American Locomotive Co.
The powerful 2-8-2 Mikado was designed to include a large firebox supported by a two-wheel trailing truck located behind the rear driving wheels. The locomotive acquired the name Mikado because the first 2-8-2 engines were built for export to Japan.
Nicknamed Mike by railroad men, it was a very successful type of locomotive. More than 14,000 were manufactured between 1920 and 1944.
Boise's Big Mike was used as an all-purpose freight engine along Union Pacific’s main line from North Platte., Neb., to Fruitland, Idaho. More on "Big Mike" can be found here.
