Chicago, Milwaukee, St. Paul and Pacific Railroad

The Milwaukee Road was the last transcontinental railroad to be built in the United States, completing its Pacific Extension to Puget Sound in 1909. The railroad's route through Montana, Idaho, and Washington featured extensive electrification through the mountains, using overhead catenary to power electric locomotives.

The Milwaukee became famous for its streamlined Hiawatha passenger trains, which were among the fastest in the world during the 1930s and 1940s. The Atlantic class 4-4-2 locomotives regularly exceeded 100 mph in revenue service on the Chicago-Minneapolis run.

The railroad's distinctive orange and maroon paint scheme was eye-catching, though it went through various variations over the years. The electrification was abandoned in 1974, and the Pacific Extension was largely abandoned in 1980.

The Milwaukee Road was absorbed into Soo Line in 1986, which later became part of Canadian Pacific. The railroad's legacy continues through preserved equipment and historical societies.
