AHM - 4456B - Boxcar, 50 Foot, Steel, Plug Door - Rio Grande - 60649

Model Information: This body style was first produced by Lima for MRC, Model Power and AHM in the 1960s and 1970s. This tooling shares the same 50' frame with several other Lima toolings including a reefer, boxcar and gondola.
Model Power refers to it as a 50' Boxcar, but the model's length is actually 45' in N scale. Hence some refer to it as a 45' Boxcar, though to our knowledge no prototype was ever produced with that length.

Prototype History: The 50-foot boxcar made its first appearance in the 1930s and steadily grew in popularity over the years, which further improved redundancies by allowing for even more space within a given car. Today, the 50-footer remains the common boxcar size. After the second world war ended, and steel became once again readily available, steel became the go-to choice for construction of boxcars. Pullman Standard and ACF were some of the most prolific builders of these cars.

In the 1960s, the flush, "plug" style sliding door was introduced as an option that provides a larger door to ease loading and unloading of certain commodities. The tight-fitting doors are better insulated and allow a car's interior to be maintained at a more even temperature.

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.

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.
