The company's main line begins at [[Portal, North Dakota]], on the [[Canada–United States border|Canada–U.S. border]], and extends southeast along former MStP&SSM trackage to the Twin Cities ([[Minneapolis–Saint Paul]]). Ex-Milwaukee Road trackage takes the Soo Line from the Twin Cities to [[Chicago]] via [[Milwaukee]]. Between Chicago and [[Detroit]], where the CPKC-owned [[Michigan Central Railway Tunnel|Detroit River Tunnel]] connects back into [[Canada]], the Soo Line has [[trackage rights]] over the [[Norfolk Southern Railway]] and [[haulage rights]] over [[CSX Transportation]].

Major branches include a connection from the border at [[Noyes, Minnesota]], to [[Glenwood, Minnesota|Glenwood]] and, until it was sold to the [[Indiana Rail Road]] in 1983, a line from Chicago to [[Louisville, Kentucky]].

Through trackage rights over the [[BNSF Railway]], the Soo Line also serves [[Duluth, Minnesota|Duluth]] from the Twin Cities.<ref>[[Canadian Pacific Railway]], [http://www8.cpr.ca/cms/NR/rdonlyres/eef3oz7bnnuiyoauwo7gvho2porfrwqoxjahivwqd4ixy4br3cnaszcek7sh2ghnnnnwdbe4eeqg46xjk6hskae2eoh/cpraif2007en.pdf In Motion: 2007 Annual Information Form], February 19, 2008, pp. 5, 7-9</ref>
