101 was built new for the Copper River & Northwestern in May 1909 by Alco’s Brooks Works. The locomotive lasted until the end of operations in 1938, and then was put to work again by the US Army to haul materials to the Milepost 13 air strip during WWII. The engine was scrapped following the war, but sources differ on exactly where. Clifford has it shipped to Ft. Richardson first, and then scrapped. Others have it scrapped in Cordova.
