The Chicago, Milwaukee, St. Paul and Pacific Railroad, often referred to as the Milwaukee Road, was a major American railroad that operated from the late 19th century until the 1980s. It connected the Midwest to the Pacific Northwest, facilitating the transport of goods and passengers across a vast network. The railroad was known for its innovative engineering and scenic routes, particularly through the Rocky Mountains. Founded in 1847, the Milwaukee Road played a significant role in the development of the regions it served. It was a pioneer in using electric locomotives in the early 20th century, especially in the mountainous areas. The railroad eventually faced financial difficulties and was merged into the Burlington Northern Railroad in 1980.
