Prototype History: The Association of American Railroads had been establishing design standards for freight cars since the early part of the century. Each new design standard meant higher capacity, lighter, more durable cars.

The Modified 1937 AAR boxcar design was a result of the industries continued search for more freight volume per carload. The real first attempt at a standardized design had been the 1932 ARA steel boxcar with an inside height of 9'-4" . In 1936 the board of the AAR approved the 1937 AAR design with a 10'-0" inside height. This became a standard throughout the industry.

Road Name History: The Denver & Rio Grande Western Railroad (reporting mark DRGW), often shortened to Rio Grande, D&RG or D&RGW, formerly the Denver & Rio Grande Railroad, was an American Class I railroad company. The railroad started as a 3 ft (914 mm) narrow gauge line running south from Denver, Colorado in 1870. It served mainly as a transcontinental bridge line between Denver, and Salt Lake City, Utah.

In 1988, the Rio Grande's parent corporation, Rio Grande Industries, purchased Southern Pacific Transportation Company, and as the result of a merger, the larger Southern Pacific Railroad name was chosen for identity. The Rio Grande operated as a separate division of the Southern Pacific, until that company was acquired by the Union Pacific Railroad. Today, most former D&RGW main lines are owned and operated by the Union Pacific while several branch lines are now operated as heritage railways by various companies.
