Soo Line Railroad

The Soo Line Railroad is one of the primary United States railroad subsidiaries for the CPKC Railway , one of six U.S. Class I railroads, controlled through the Soo Line Corporation. Although it is named for the Minneapolis, St. Paul and Sault Ste. Marie Railroad (MStP&SSM), which was commonly known as the Soo Line after the phonetic spelling of Sault, it was formed in 1961 by the consolidation of that company with two other CPKC subsidiaries: The Duluth, South Shore and Atlantic Railway, and the Wisconsin Central Railway. It is also the successor to other Class I railroads, including the Minneapolis, Northfield and Southern Railway (acquired 1982) and the Chicago, Milwaukee, St. Paul and Pacific Railroad (Milwaukee Road, acquired at bankruptcy in 1985). On the other hand, a large amount of mileage was spun off in 1987 to Wisconsin Central Ltd., now part of the Canadian National Railway. The Soo Line Railroad and the Delaware and Hudson Railway, CPKC's other major subsidiary (before the 2008 DM&E acquisition), presently do business as the Canadian Pacific Railway (CP). Most equipment has been repainted into the CP scheme, but the U.S. Surface Transportation Board groups all of the company's U.S. subsidiaries under the Soo Line name for reporting purposes. The Minneapolis headquarters are in the Canadian Pacific Plaza building, having moved from the nearby Soo Line Building. System description The company's main line begins at Portal, North Dakota, on the 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 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 and, until it was sold to the Indiana Rail Road in 1983, a line from Chicago to Louisville, Kentucky.
