Soo Line Railroad

Soo Line Railroad is a United States railroad company and one of the principal U.S. operating subsidiaries associated with Canadian Pacific Kansas City. Its reporting mark is SOO. The company takes its name from the Minneapolis, St. Paul and Sault Ste. Marie Railroad, commonly called the Soo Line because “Sault” was pronounced and represented phonetically as “Soo.” The present corporation was created in 1961 when Canadian Pacific consolidated the Minneapolis, St. Paul and Sault Ste. Marie Railroad with two other Canadian Pacific subsidiaries, the Duluth, South Shore and Atlantic Railway and the Wisconsin Central Railway. The Soo Line developed as a bridge between Canadian Pacific’s Canadian system and important industrial, agricultural, and population centers in the United States. Its principal route runs from Portal, North Dakota, on the Canadian border, southeast through the Upper Midwest to the Minneapolis–Saint Paul area. Former Milwaukee Road infrastructure links the Twin Cities with Milwaukee and Chicago. The company also reaches Detroit through trackage rights over Norfolk Southern and haulage rights over CSX, with the Canadian Pacific-controlled Detroit River Tunnel providing a connection back into Canada. Trackage rights over BNSF Railway provide access to Duluth. Soo Line’s business is primarily freight transportation rather than passenger service. Its network historically handled grain and other agricultural products, coal, forest products, industrial commodities, manufactured goods, and intermodal traffic. In 1970, the railroad operated approximately 4,693 route miles and 6,104 track miles, reporting 8,249 million revenue ton-miles of freight. Passenger operations were largely discontinued after the 1961 consolidation, although several inherited named trains continued for periods during the 1960s. The company expanded its position in the Twin Cities market through control of the Minneapolis, Northfield and Southern Railway in 1982. It then acquired the assets of the bankrupt Chicago, Milwaukee, St. Paul and Pacific Railroad, commonly known as the Milwaukee Road, in 1985. The Milwaukee Road and the Minneapolis, Northfield and Southern were merged into Soo Line Railroad in 1986. Soo Line subsequently created the Lake States Transportation Division to operate less strategic routes. Much of that approximately 2,000-mile segment was sold in 1987 to Wisconsin Central Ltd., whose system later became part of Canadian National Railway. Canadian Pacific established Soo Line Corporation as a holding company in 1984 and obtained full control of it in 1990. During the 2000s, the Soo Line’s operations were increasingly consolidated with Canadian Pacific’s broader U.S. network. Although equipment and operating identity largely shifted to Canadian Pacific branding, regulatory and reporting practices have continued to group many U.S. subsidiaries under the Soo Line name. Following Canadian Pacific’s combination with Kansas City Southern, the railroad sits within the wider Canadian Pacific Kansas City system. Its Minneapolis headquarters moved to the Canadian Pacific Plaza building. The Soo Line’s historic physical legacy also survives outside active freight operations. Former rights-of-way have been converted into recreational trails in Minnesota, Wisconsin, and Michigan, including the Soo Line Trail, the Wolf River State Trail, and routes associated with the former Copper Country Limited. Several locomotives, passenger cars, and cabooses have been preserved by railroad museums and historical organizations.

The legal predecessor of the present Soo Line Railroad was incorporated in Minnesota on October 19, 1949, as the Duluth, South Shore and Atlantic Railroad. It was formed in connection with the reorganization of the Duluth, South Shore and Atlantic Railway and its subsidiary, the Mineral Range Railroad. The company became the vehicle for Canadian Pacific’s later consolidation of several U.S. subsidiaries. On January 1, 1961, Canadian Pacific merged the Minneapolis, St. Paul and Sault Ste. Marie Railroad and the Wisconsin Central Railway into the reorganized company and renamed it Soo Line Railroad. The new railroad inherited a broad Upper Midwest network and the Soo Line name associated with the Minneapolis, St. Paul and Sault Ste. Marie. Its principal role was to connect Canadian Pacific routes with the American Midwest, particularly the Twin Cities, Wisconsin, Chicago, and border gateways. The 1961 merger sharply reduced passenger activity. The daytime Saint Paul–Duluth service ended in June 1961. The Soo-Dominion, which connected Saint Paul with Portal and had seasonal connections toward western Canada, ended in December 1963. The overnight Laker between Chicago and Duluth and its Saint Paul connection ended in January 1965, while the Winnipeger between Saint Paul and Winnipeg ended in March 1967. The Copper Country Limited, operated jointly with the Milwaukee Road and inherited from the Duluth, South Shore and Atlantic, made its final run between Chicago and Michigan’s Copper Country on May 8, 1968. Mixed trains continued on some routes for a time, but the company’s business became overwhelmingly freight-oriented. Soo Line expanded in the Twin Cities region in June 1982 when it gained control of the Minneapolis, Northfield and Southern Railway. In 1984, Canadian Pacific incorporated Soo Line Corporation in Minnesota as a holding company and exchanged stock in December to give the corporation total control of the railroad. The following year, on February 19, 1985, Soo Line acquired the assets of the bankrupt Chicago, Milwaukee, St. Paul and Pacific Railroad. Those properties were initially assigned to a newly created subsidiary, The Milwaukee Road, Inc. The Milwaukee Road and the Minneapolis, Northfield and Southern were merged into Soo Line Railroad effective January 1, 1986. The enlarged network created pressure to reduce costs and focus on the most strategically important routes. On February 10, 1986, Soo Line created the Lake States Transportation Division to operate less important lines, including the former Wisconsin Central route between Chicago and the Twin Cities. After proposed labor-rule changes could not be implemented, Soo Line sold approximately 2,000 miles of the division to Wisconsin Central Ltd. in 1987 for $133 million. Wisconsin Central later became part of Canadian National Railway in 2001. The transaction represented a significant reshaping of Soo Line’s route structure rather than a simple continuation of its inherited network. Canadian Pacific obtained full control of Soo Line Corporation in 1990, having previously owned approximately 56 percent of its common stock. In the 2000s, Soo Line operations were consolidated into Canadian Pacific. Much of the equipment was repainted in Canadian Pacific colors, and the railroad’s operating identity became less visually distinct. Nevertheless, the U.S. Surface Transportation Board continued to group Canadian Pacific’s U.S. subsidiaries under the Soo Line name for reporting purposes, and the railroad remained a significant legal and operating component of the Canadian Pacific system. The surviving network is centered on a border-to-Midwest freight corridor. The main line extends from Portal, North Dakota, to the Twin Cities, then continues over former Milwaukee Road routes toward Milwaukee and Chicago. The company reaches Detroit through rights over Norfolk Southern and haulage rights over CSX, while the Canadian Pacific-controlled Detroit River Tunnel reconnects the route with Canada. Soo Line also reaches Duluth through trackage rights over BNSF Railway. Former Soo Line routes have been repurposed as trails in Minnesota, Wisconsin, and Michigan, while preserved locomotives, passenger equipment, and cabooses document the railroad’s earlier eras. Within the modern Canadian Pacific Kansas City system, the Soo Line name continues to identify an important U.S. railroad subsidiary and reporting entity.

A Midwest-focused Class I freight railroad and Canadian Pacific Kansas City subsidiary linking Canadian gateways with the Twin Cities, Chicago, Milwaukee, Duluth, and Detroit markets.

• Rail freight transportationFreight rail1961

  Soo Line’s core activity is the movement of freight over a Midwest network connected to Canadian Pacific routes. The railroad serves agricultural, industrial, forest-product, manufactured-goods, and other commodity flows. Its route structure provides Canadian gateways with access to the Twin Cities, Milwaukee, Chicago, Duluth, and Detroit-area markets.

• Intermodal and connecting rail servicesLogistics and rail connectivity

  The Soo Line participates in freight movements that depend on connections with other Class I railroads. Access to Detroit involves Norfolk Southern trackage rights and CSX haulage rights, while BNSF trackage rights provide access to Duluth. These arrangements extend the commercial reach of the railroad beyond its directly operated route mileage.

• Named passenger trainsHistorical passenger rail1961

  Passenger services inherited or operated by Soo Line included the Laker, Soo-Dominion, Winnipeger, and Copper Country Limited. Most passenger operations disappeared during the 1960s as the company concentrated on freight transportation. The Copper Country Limited was the final named passenger service associated with the railroad.
