AHM - 4459G - Caboose, Bay Window - Union Pacific - 4066

Model Information: This model was originally produced by Lima for AHM. They were later imported by PMI and Model Power. Model Power moved the tooling to China and updated it a little. The retooled cabooses are very similar to the earlier Lima product. They can be told apart by examining whether the bays in are separately applied parts. The original Lima version has the parts applied whereas the Chinese version has the bays as part of the body mold. The trucks are "snap-in" and do not use kingpins. This will make it difficult to swap out the trucks for modern MTL trucks - a coupler transplant will need to be done.

For Model Power releases, since it is not marked on the body shell where the model was made. However the boxes for these cabooses will clearly indicate whether they were made in Italy or Hong Kong.

Prototype History: In a bay window caboose, the crew monitoring the train sits in the middle of the car in a section of wall that projects from the side of the caboose. The windows set into these extended walls resemble architectural bay windows, so the caboose type is called a bay window caboose. This type afforded a better view of the side of the train and eliminated the falling hazard of the cupola. The bay window gained favor with many railroads because it eliminated the need for additional clearances in tunnels and overpasses. On the west coast, the Milwaukee Road and the Northern Pacifc Railway used these cars, converting over 900 roof top cabooses to bay window cabooses in the late 1930's. Milwaukee Road rib-side window cabooses are preserved at New Libson, Wisconsin, the Illinois Railway Museum, the Mt. Rainer Scenic Railroad, and Cedarburg, Wisconsin.

When the shift was made from wooden to steel caboose construction, a new type of caboose also arrived. The new caboose design replaced the traditional roof-mounted “cupola” with “bay-windows” attached to the sides of the caboose. As freight cars grew taller, the effectiveness of cupolas as practical observation points was diminished. This was especially true on lines that suffered from low clearances and were incapable of making cupolas high enough to see over the top of the tallest freight cars. Cabooses were prone to rough handling, and many a trainman was knocked out of his perch in the cupola and injured when he fell. The new caboose design was safer as well as more effective.

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.
