The Chicago and Milwaukee Subdivision (commonly referred to as the C&M Subdivision or C&M Sub) is a 85.5-mile (137.6 km) railway line running between Chicago, Illinois and Milwaukee, Wisconsin. It is mostly dispatched by Canadian Pacific Kansas City Limited (through its primary United States subsidiary, the Soo Line Railroad) from a CP Rail facility in Minneapolis. From Pacific Junction (Tower A-5) to Chicago Union Station, it is dispatched by Metra's Consolidated Control Facility.[1] The C&M Subdivision is the primary of CPKC's two northern routes from Chicago.[2] The Union Pacific Railroad operates its Milwaukee Subdivision, a former Chicago & Northwestern Railway line, parallel to the C&M (albeit to the east).

From Chicago Union Station to Pacific Junction (Tower A-5), the territory is triple tracked and primarily hosts Amtrak and Metra trains. From Pacific Junction (Tower A-5) to Milwaukee, it is double tracked. Freight trains do not go further south of Pacific Junction (Tower A-5) unless they are reversing to access the Belt Railway of Chicago at Cragin Junction (where the Milwaukee District West Line's Grand/Cicero station is located). This junction is the northernmost point of the Belt Railway.[3]

The line carries Amtrak's Empire Builder, Borealis, and Hiawatha,[4] while Metra operates trains on the Milwaukee District North Line between Union Station and Rondout.[1] The Wisconsin & Southern Railroad runs freight services from Janesville, Wisconsin to Chicago WSOR using trackage rights south of Rondout.[5][6] Canadian Pacific also runs frequent freight trains on this line.

History

The line had previously been owned by the Chicago, Milwaukee, St. Paul and Pacific Railroad, commonly known as the Milwaukee Road.[7][8] It once carried the Milwaukee Road's fast Hiawatha passenger trains, including trains that regularly exceeded 100 miles per hour (160 km/h). For several years in the 1940s and early 1950s, trains were scheduled to run along this stretch in 75 minutes or less.[9] While stricter regulations eventually reduced the speed limit to 79 miles per hour (127 km/h) along this stretch, plans are in place as of 2010^[update] to improve the line to support speeds up to 110 miles per hour (180 km/h)—modestly faster than historic trains that used the route.[10]
