AHM - 4268 - Locomotive, Diesel, Plymouth MDT - Union Pacific - 720

Model Information: Although this model only somewhat resembles a Plymouth MDT, it was marketed as such by Lima. It was also marketed as a BR D2785 0-4-0 as well as some kind of German prototype. In the 1980s, N Scale modelers had to accept what was offered and the manufacturers had to get as much return on investment for a tooling as possible.

Prototype History: The Plymouth Locomotive Works was founded in 1910. They specialized in small switcher locomotives for industrial use. The MDT was the 4-wheel model of their diesel switcher.

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: AHM is the initials for Associated Hobby Manufacturers, Inc. The company was founded in 1959 as a reseller of other companies' model railroad components. Initially an HO company, they entered into N Scale in the early 1970's as an importer of products made by Roco in Austria. For N Scale products, AHM apparently contracted to use the exact same molds as were used by Roco to produce early Atlas models. They also contracted with Rivarossi to make locomotives.

When AHM went out of business IHC picked up some of their line. Also, at least one body style was taken over by Eastern Seaboard models.

Manufacturer Information: Lima S.p.A (Lima Models) was a brand of railway models made in Vicenza, Italy, for almost 50 years, from the early 1950s until the company ceased trading in 2004. Lima was a popular, affordable brand of 00 gauge and N gauge model railway material in the UK, more detailed H0 and N gauge models in France, Germany, Italy, Switzerland, and the United States as well as South Africa, Scandinavia and Australia. Lima also produced a small range of 0 gauge models. Lima partnered with various distributors and manufacturers, selling under brands such as A.H.M., Model Power, Minitrain and PMI (Precision Models of Italy). Market pressures from superior Far Eastern produce in the mid-1990s led to Lima merging with Rivarossi, Arnold, and Jouef. Ultimately, these consolidations failed and operations ceased in 2004.

Hornby Railways offered €8 million to acquire Lima's assets (including tooling, inventory, and the various brand names) in March of the same year, the Italian bankruptcy court of Brescia (town near Milan, last headquarters of Lima) approving the offer later that year. In December 2004, Hornby Railways formally announced the acquisition along with the Rivarossi (H0 North American and Italian prototypes), Arnold (N scale European prototypes), Jouef (H0 scale French prototypes), and Pocher (die-cast metal automobile kits) ranges. As of mid-2006, a range of these products has been made available under the Hornby International brand, refitted with NEM couplings and sprung buffers and sockets for DCC (Digital Command Control) decoders.
