The Fox Lake Subdivision is a railway stretch measuring 17.5 miles located in Illinois. It extends from a connection 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. This line is owned and managed by Metra, the commuter rail agency serving the Chicago metropolitan area, and it accommodates the commuter trains on the Milwaukee District North Line. The track is mainly single, featuring a passing siding near Grayslake.
Historically, this subdivision formed part of the former Milwaukee Road route that linked Chicago to Madison, Wisconsin. The section north of Fox Lake up to Janesville, Wisconsin is under the ownership of the Wisconsin & Southern Railroad, which holds trackage rights over Metra’s portion. Beyond Metra’s Fox Lake station heading northward, the rail line is utilized solely for freight services.
