The Spokane International Railroad was a short line railroad between Spokane, Washington, and the Canadian Pacific Railway at Kingsgate, British Columbia. The line became an important one for the CP with its connections to the Union Pacific Railroad and Portland, Oregon. The line, originally named the Spokane International Railway, was built by local businessman and railroader Daniel Chase Corbin following an agreement between him and the CP, with CP agreeing to fund much of the line's construction and to secure the loan by holding the new line's bonds. Especially significant was that the CP controlled the Minneapolis, St. Paul and Sault Ste. Marie Railway and its connections to Minneapolis, Minnesota, Saint Paul, Minnesota, and Chicago, Illinois. Completion of the Spokane International now meant that the CP could compete with the Northern Pacific Railway and Great Northern Railway lines for transportation between the Midwest and the Puget Sound area. Express passenger service was soon introduced on the line via the Soo-Spokane Train De Luxe. The SI was reorganized October 1, 1941, following financial difficulties and receivership during the Great Depression. The line was renamed the Spokane International Railroad as part of the restructuring agreement until the 1950s. On October 6, 1958, the UnionPacific Railroad took control of Spokane International Railroad. In 1962 UP leased SI's 11 ALCO RS-1 locomotives for operation. The locomotives were later repainted to UP's yellow and gray paint scheme, but retained their SI lettering. Also in 1962, UP sold four of its older steel cabooses to SI. These were also painted in UP's yellow scheme, but received SI lettering and numbers. After UP's 1958 control of SI, Union Pacific continued to lease SI for operation. On December 31, 1987, Union Pacific formally merged SI into its corporate structure. At the end of 1960 SI operated 150 miles of road on 190 miles of track; that year it reported 141 million net ton-miles of revenue freight and zero passengers. The line remains in operation as an important UP connection between southern British Columbia and the northwest United States.
