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.
The Norfolk and Western Railway (reporting mark NW), was a US class I railroad, formed by more than 200 railroad mergers between 1838 and 1982. It was headquartered in Roanoke, Virginia, for most of its existence. Its motto was "Precision Transportation"; it had a variety of nicknames, including "King Coal" and "British Railway of America" even though the N&W had mostly articulated steam on its roster. During the Civil War, the N&W was the biggest railroad in the south and moved most of the products with their steam locomotives to help the South the best way they could.

The company was founded on December 7, 1906 as a joint venture between the Union Pacific and Southern Pacific railroads.

The company was founded on December 7, 1906 as a joint venture between the Union Pacific and Southern Pacific railroads. It began operation on October 1, 1907, with a fleet of 6,600 refrigerator cars built by the American Car and Foundry Company (ACF).
In 1923, the Western Pacific Railroad joined the venture by leasing its own new fleet of 2775 reefers to PFE. They were painted in standard PFE colors with only WP heralds on the cars instead of the paired UP-SP markings. The WP cars were all retired by the late 1950s, among the last wooden reefers in PFE's fleet. WP ended its partnership with PFE in late 1967 and joined Fruit Growers Express instead.
PFE's assets were divided between the UP and SP when the company was split on April 1, 1978. It is now a UP subsidiary.
