The Wisconsin and Southern Railroad (reporting marks WAMX, WSOR) is a Class II regional railroad in Southern Wisconsin and Northeastern Illinois currently operated by Watco. It operates former Chicago, Milwaukee, St. Paul and Pacific Railroad (Milwaukee Road) and Chicago and North Western Railway (C&NW) trackage, mostly acquired by the state of Wisconsin in the 1980s. Within Wisconsin, WSOR connects with four western Class I railroads: BNSF Railway, Canadian National Railway, Canadian Pacific Railway, and Union Pacific Railroad. Through trackage rights over Metra, WSOR accesses Chicago to connect with the two eastern Class I railroads, CSX Transportation and Norfolk Southern Railway. WSOR also has access to harbor facilities in Prairie du Chien, and transload facilities are located in Milwaukee, Janesville, Madison, and Oshkosh. 22 grain elevators have located rail load-out facilities on the WSOR system.[citation needed] For train operation purposes, the WSOR system is divided into two divisions, the Northern Division and the Southern Division. The Northern Division is essentially the original WSOR trackage from 1980, with a few new lines that have been added around the Milwaukee area since the 1990s. It includes the line northwest from Milwaukee to Horicon, where it splits into branches to Cambria and Oshkosh, as well as a line from Milwaukee north to Kiel. The Southern Division includes the lines acquired from the Wisconsin and Calumet Railroad in 1992, centered on Madison and Janesville, as well as several lines acquired in the 1990s in the Madison area. The two divisions are not physically connected with WSOR-owned trackage, but trackage rights over a short section of Canadian National's Waukesha Subdivision from Waukesha to Slinger provide a link between the two divisions.[1] WSOR is headquartered in Madison, which is also a central hub terminal. The train dispatching office is located in Horicon. Locomotive maintenance is centered in Janesville, with secondary work also being performed at Horicon. WSOR's Horicon paint shops perform contract work on both rolling stock and locomotives. SD40-2-WSOR (Horns Are K5LA-P3) SD60 WAMX
