Chicago Northwestern

The Chicago Northwestern railroad was a class 1 from 1859-1995.

The Chicago and North Western Transportation Company (reporting mark CNW) was a Class I railroad in the Midwestern United States. It was also known as the "North Western". The railroad operated more than 5,000 miles (8,000 km) of track as of the turn of the 20th century, and over 12,000 miles (19,000 km) of track in seven states before retrenchment in the late 1970s. Until 1972, when the employees purchased the company, it was named the Chicago and North Western Railway (or Chicago and North Western Railway Company).

The C&NW became one of the longest railroads in the United States as a result of mergers with other railroads, such as the Chicago Great Western Railway, Minneapolis and St. Louis Railway and others. By 1995, track sales and abandonment had reduced the total mileage to about 5,000. The majority of the abandoned and sold lines were lightly trafficked branches in Iowa, Illinois, Minnesota, South Dakota and Wisconsin. Large line sales, such as those that resulted in the Dakota, Minnesota and Eastern Railroad, further helped reduce the railroad to a mainline core with several regional feeders and branches. Union Pacific (UP) purchased the company in April 1995 and integrated it with its own operation as of 2021 3 CNW are still painted in original colors on the UP 2   are  stored  and  6706 is in service.However, it is still possible to find untouched C&NW units in service.
