The Chicago, Milwaukee, St. Paul and Pacific Railroad (often referred to as the Milwaukee Road) (reporting mark MILW), was a Class I railroad that operated in the Midwest and Northwest of the United States from 1847 until 1980, when its Pacific Extension (Montana, Idaho, and Washington) was abandoned following a bankruptcy. Around this time, the company went through several official names and faced bankruptcy on multiple occasions. The eastern half of the system merged into the Soo Line Railroad on January 1, 1986, a subsidiary of Canadian Pacific Railway (reporting mark CP). Although the "Milwaukee Road" as such ceased to exist, much of its track continues to be used by multiple railroads.
