Maine Central Railroad Class S locomotives were intended for heavy freight service. They were of 2-8-2 wheel arrangement in the Whyte notation or 1’D1′ in UIC classification. They replaced earlier class W 2-8-0 locomotives beginning in 1914. They were the largest and most modern steam freight locomotives built for Maine Central; although former Boston and Maine Railroad 2-10-2s were later purchased to handle World War II freight traffic.
