AHM - 4346 - Tank Car, Single Dome, 39 Foot - Dupont - 6048

Prototype History: Single Dome tank cars are a railroad staple. They have been around since the first half of the 20th century. This length car can handle about 10,000 gallons. These railcars carry a wide array of commodities, including liquid fertilizers, chemicals, fuel oils and asphalt, and food-grade oils. Tank cars can be pressurized or non-pressurized, insulated or non-insulated. Single dome cars carry only a single commodity at once. Food-service tank cars may be lined with stainless steel, glass, or plastic. Tank cars carrying dangerous goods are generally made of different types of steel, depending on the intended cargo and operating pressure. They may also be lined with rubber or coated with specialized coatings for tank protection or product purity purpose. The tank heads are also stronger to prevent ruptures during accidents.

One common version is the ACF Type 27 jacketed tank car with expansion dome which was in common use by many railroads and oil companies.

Road Name History: E. I. du Pont de Nemours and Company, commonly referred to as DuPont, is an American conglomerate that was founded in July 1802 as a gunpowder mill by French Eleuthere Irenee du Pont.

In the 20th century, DuPont developed many polymers such as Vespel, neoprene, nylon, Corian, Teflon, Mylar, Kevlar, Zemdrain, M5 fiber, Nomex, Tyvek, Sorona, Corfam, and Lycra. DuPont developed Freon (chlorofluorocarbons) for the refrigerant industry, and later more environmentally friendly refrigerants. It also developed synthetic pigments and paints including ChromaFlair.

In 2014, DuPont was the world's fourth largest chemical company based on market capitalization and eighth based on revenue. Its stock price is a component of the Dow Jones Industrial Average.

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.
