Locomotive, Diesel, Alco PA/PB

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.

Railroad/Company: The American Locomotive Company, often shortened to ALCO, ALCo or Alco, designed, built and sold steam locomotives, diesel-electric locomotives, diesel engines and generators, specialized forgings, high quality steel, armed tanks and automobiles and produced nuclear energy. The American Locomotive Company was formed in 1901 by the merger of Schenectady Locomotive Engine Manufactory of Schenectady, New York with seven smaller locomotive manufacturers.

The American Locomotive Automobile Company subsidiary designed and manufactured automobiles under the Alco brand from 1905-1913 and produced nuclear energy from 1954-1962. The company changed its name to Alco Products, Incorporated in 1955. In 1964 the Worthington Corporation acquired the company. The company ceased trading in 1969.
