Built in July 1900 by the Baldwin Locomotive Works of Philadelphia, engine 950 was the world's largest steam locomotive, weighing 190,000 pounds and producing a tractive effort of 47,090 pounds. Originally numbered 600 by the Soo Line, it was the only decapod in the Soo Line roster and entered service between Minneapolis, Minnesota and Sault Ste. Marie, Michigan. In 1912 it was assigned to the ore docks in Superior, Wisconsin and renumbered 950, where it worked until ore operations ceased there in 1929. It was then transferred to yard duties in Minneapolis/St. Paul until 1942, when it came to Ashland to work the ore docks there. After steam operations ended in 1954, the engine was retired, and in 1956 it was donated to the City of Ashland. It was dedicated at a park at Stuntz Avenue and US Hwy 2 on July 4, 1957, and moved to its present location in 1987 during the Soo Line Depot restoration project.
