It runs 17.5 miles (28.2 km) from a junction with the C&M Subdivision of the CPKC Railway at Rondout, Illinois, to a junction with the Wisconsin and Southern Railroad at Fox Lake, Illinois. Metra, the commuter rail authority for the Chicago area, owns and operates the line. The line hosts Milwaukee District North Line commuter trains.[1] The entire line is single tracked, with the exception of a passing siding at Grayslake. The line is part of the former Milwaukee Road route between Chicago and Madison, Wisconsin. The Wisconsin & Southern owns the portion between Fox Lake and Janesville, Wisconsin, and has trackage rights over the Metra portion.[2] The tracks north of Metra's Fox Lake station host exclusively freight traffic.
