Aurora Postage Stamp - 4871-210 - Locomotive, Diesel, EMD F9 - Union Pacific - 510

Specific Item Information: Dummy A-Unit

Model Information: Introduced in 1966 as Aurora Postage Stamp models. Though Minitrix sold these as F9, the vent and porthole configuration suggest a F7.

Prototype History: The EMD F9 was a 1,750 horsepower (1,300 kW) Diesel-electric locomotive produced between February 1953 and May 1960 by the Electro-Motive Division of General Motors (EMD) and General Motors Diesel (GMD). It succeeded the F7 model in GM-EMD's F-unit sequence. Final assembly was at GM-EMD's La Grange, Illinois plant. The F9 was also built in Canada by General Motors Diesel at their London, Ontario plant. A total of 100 cab-equipped lead A units and 154 cabless booster B units were built. The F9 was the fifth model in GM-EMD's highly successful "F" series of cab unit diesel locomotives.

A F9 can be distinguished reliably from a late F7 only by the addition of an extra filter grille ahead of the front porthole on the side panels on A units. Internally, the use of an 567C prime mover increased power to 1,750 hp from the F7's 1,500 hp.

By the time cab units such as the F9 were built, railroads were turning to the road switcher-style of locomotive, and the F9 was succeeded in most part by the EMD GP9.

Road Name History: The Union Pacific Railroad (reporting mark UP) is a freight hauling railroad that operates 8,500 locomotives over 32,100 route-miles in 23 states west of Chicago, Illinois and New Orleans, Louisiana. The Union Pacific Railroad network is the largest in the United States and employs 42,600 people. It is also one of the world's largest transportation companies.

Union Pacific Railroad is the principal operating company of Union Pacific Corporation (NYSE: UNP); both are headquartered in Omaha, Nebraska. Over the years Union Pacific Corporation has grown by acquiring other railroads, notably the Missouri Pacific, Chicago & North Western, Western Pacific, Missouri-Kansas-Texas, and the Southern Pacific (including the Denver & Rio Grande Western).

Union Pacific Corporation's main competitor is the BNSF Railway, the nation's second largest freight railroad, which also primarily services the Continental U.S. west of the Mississippi River. Together, the two railroads have a duopoly on all transcontinental freight rail lines in the U.S.

Brand/Importer Information: In 1967, Aurora Plastics Corporation started importing the Minitrix N Scale product line. These trains were marketed as Postage Stamp Trains. It was a bold entry into what would become a very active market in the new N-Scale model train market. The basic starter set took advantage of N-Scale’s small size by packaging everything necessary for a small model railroad in a book-like box. The larger starter sets were packaged in more conventional boxes. Aurora went out of business in 1977.

The Body styles of this product line were made in Austria by Roco, imported into the United States by Minitrix and then rebranded by Aurora. Some of the exact same molds were also produced by Roco for Atlas who branded them using their own name.
