In July 1944, the Milwaukee Road took an order of (10) 4-8-4 Northerns from the American Locomotive Company.  Numbered 260-269, they were designated the S-3 class, and were used for heavy mainline freights and occasionally subbing on crack passenger trains. Far from being the heaviest or fastest 4-8-4’s, they were certainly of the most modernized. Weighing in at 460,000 lbs, they produced 4500 hp and had a maximum speed of 100mph. They sat on (8) 74″ boxpox drive wheels. They sported a few unusual features as well. An all weather enclosed cab due to the sub-zero winter temperatures, a combination sand and steam dome, an red oscillating Mars Light, a massive cast steal pilot with folding coupler, and probably the most unusual, an air horn. Unlike the Milwaukee Road’s Streamlined A class 4-4-2 Atlantics used in Hiawatha Service, the S-3 4-8-4’s were also equipped with 3 chime steam whistles. The S-3’s had a very short career, only 10 years. When the Milwaukee Road did away with steam locomotives in 1954, (8) of the 10 4-8-4’s were scrapped.

#261 was donated to the National Railroad Museum in Green Bay Wisconsin in 1958. She sat on display for just over 20 years when “North Star Rail” leased #261 and moved her to Minneapolis for a full restoration. She was fired up in 1993 and has been running ever since. 261 was purchased from the museum in May, 2010 for $225,000. She is now property of “The Friends of the 261.”

#265 is on display at the Illinois Railway Museum in Union, IL.
