Prototype History: ALCO PA (DL-304/DL-305) refers to a family of A1A-A1A diesel locomotives built to haul high-speed passenger trains that were built in Schenectady, New York, in the United States by a partnership of the American Locomotive Company (ALCO) and General Electric (GE) between June, 1946 and December, 1953. They were of a cab unit design, and both cab-equipped lead A unit PA and cabless booster B unit PB models were built. ALCO's beautiful PA-1 is one of America's most famous locomotives. It was ALCO's entry into the passenger train diesel craze, competing directly with the E-Units from EMD. The first PA1 celebrated Alco's 75,000th loco to roll out of the erecting shop.

The PAs, as well as their cousins, the ALCO FAs, were born as a result of Alco's development of a new diesel engine design, the Model 244. In early 1944, development started on the new design. In 1946, this new locomotive made its debut on the Texas and New Orleans Railroad. Southern Pacific PA's #6055 and 6056 were later put into service on the SP's coastal division, pulling trains such as the Morning Daylight.
Having more horsepower than their leading competitor, Alco felt that they had a fleet-ready competitive product. PA1's were sleek, stylish, powerful, and were very well suited for America's passenger and fast freight trains. Additionally, their 65' 8" bodies became excellent billboard advertising for the railroads that they served with pride.
The PA-1/PB-1 were rated 2,000 hp (1,490 kW) and the PA-2/PB-2 2,250 hp (1,680 kW). A total of 297 PA/PB have been built between 1946 and 1953.

ALCO locomotives were also used in service with the famous "California Zephyr" passenger train, adopting a number of paint schemes, the most famous of which was perhaps the "Prospector" paint scheme. This paint scheme was a striking two-tone silver and gold arrangement, highlighted by a series of four black stripes going down the side of the body.

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.
