AHM - 4441C - Covered Hopper, 4-Bay, ACF Centerflow - Burlington Route - 18517

Model Information: AHM contracted Roco to use the "Centerflow" hopper mold to produce cars. This mold has "Atlas Austria" written on the base of the car. To our knowledge Atlas did not sell this car. Apparently they asked Roco to design it but never ordered it into production. At least we have yet to spot this mold in any Atlas catalogs. When AHM stopped making this car, Eastern Seaboard models contracted Roco to keep making new releases, and these also have "Atlas Austria" on the bottoms of the cars.

Prototype History: Contemporary 2-bay covered hoppers, like ACF's Centerflows, were 100-ton cars designed to haul dense loads, like cement. Their larger 3 and 4-bay brethren, while usually still having 100 ton capacities, were designed for lighter-density loads, like grain or flour. Their sizes had to do with the fact that a low-density product like grain will "cube out" the cubic capacity of a smaller 2-bay car way before you hit the cars' tonnage rating. Conversely, load a 3 or 4-bay covered hopper to its cubic maximum with a dense product like cement, and you'll wind up with a seriously overloaded car tonnage wise. In short, keep the smaller 2-bay cars for heavy commodities, and keep the larger cars for lighter loads like grains, sugar, flour, etc.

Road Name History: The Chicago, Burlington and Quincy Railroad (reporting mark CBQ) was a railroad that operated in the Midwestern United States. Commonly referred to as the Burlington or as the Q, the Burlington Route served a large area, including extensive trackage in the states of Colorado, Illinois, Iowa, Kentucky, Missouri, Montana, Nebraska, Wisconsin, Wyoming, and also in New Mexico and Texas through subsidiaries Colorado and Southern Railway, Fort Worth and Denver Railway, and Burlington-Rock Island Railroad.[citation needed] Its primary connections included Chicago, Minneapolis-St. Paul, St. Louis, Kansas City and Denver. Because of this extensive trackage in the midwest and mountain states, the railroad used the advertising slogans "Everywhere West", "Way of the Zephyrs", and "The Way West". It merged into Burlington Northern in 1970.

In 1967, it reported 19,565 million net ton-miles of revenue freight and 723 million passenger miles; corresponding totals for C&S were 1,100 and 10 and for FW&D were 1,466 and 13. At the end of the year CB&Q operated 8,538 route-miles, C&S operated 708 and FW&D operated 1362. (These totals may or may not include the former Burlington-Rock Island Railroad.)

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: The company was founded in 1960 by Ing. Heinz Rössler and started with a plastic Minitanks series of military vehicles. After export to the USA became successful, the model line was expanded with model trains in HO scale and the smaller N scale. TT scale was also subsequently added to the product line. The model rail product line covers many European countries including Germany, Belgium, Luxembourg, France, Spain, Austria, Italy, Switzerland, Sweden and the Netherlands, and also the USA.

On July 15, 2005 ROCO Modellspielwaren GmbH was declared bankrupt. From July 25 the company continues as Modelleisenbahn GmbH, but still uses the Roco brand and associated logo. On October 1, 2007, distribution of the 'Minitank' product series was assigned to the German model car manufacturer Herpa.

Since February 2008 Modelleisenbahn also owns Fleischmann, which like Roco had gone bankrupt. The two companies continue as separate brands under Modelleisenbahn GmbH, while benefiting from economies of scale through joined development projects, marketing and procurement.
