Minitrix - 3127 - Reefer, 50 Foot, Mechanical - Swift Refrigerator Line - 4226

Model Information: Produced by Roco and imported by AHM, this 50 Foot Mechanical Reefer was released in the late 1960s and early 1970s.

Prototype History: The purpose of a mechanical reefer is to keep perishable items cold. Early reefers were of all wood construction and used ice for cooling. By the 1940s, new reefers were being built entirely of steel. Insulating techniques improved to the point where economical refrigeration could be accomplished using steel side plates in place of wood sheathing. Fifty foot mechanical reefers date back to at least the late 50s / early 60s.

The mechanical reefers could keep a more regular temperature, and often times colder than what the ice bunker cars were capable of. Initially mechanical reefers were used primarily in frozen food service. This would soon change as mechanical refrigeration began to replace ice-based systems. Soon after, mechanical refrigeration units replaced the “armies” of personnel required to re-ice the cars.

Road Name History: The Swift Refrigerator Line (SRL, also known as the Swift Refrigerator Transportation Company) was a private refrigerator car line established around 1875 by Chicago meat packer Gustavus Swift, the founder of Swift and Company. Ad for the line from 1921. Shows sample Swift cars at the top and a map of the distribution locations.

Swift hoped to develop an alternative to transporting live cattle across the Midwest. He experimented by moving dressed (cut) meat using a string of ten boxcars which ran with their doors removed, and made a few test shipments to New York during the winter months over the Grand Trunk Railway (GTR). The method proved too limited to be practical.

In 1878, Swift hired engineer Andrew Chase to design a ventilated car that was well-insulated, and positioned the ice in a compartment at the top of the car, allowing the chilled air to flow naturally downward. The meat was packed tightly at the bottom of the car to keep the center of gravity low and to prevent the cargo from shifting. Chase's design proved to be a practical solution to providing temperature-controlled carriage of dressed meats, and allowed Swift & Company to ship their products all over the United States, and even internationally, and in doing so radically altered the meat business.

The General American Transportation Corporation (GATX) assumed ownership of the line in 1930.

Brand/Importer Information: Trix is a German company that originally made Trix metal construction sets. one of its co-founders was Stephan Bing, the son of the pioneer toy-maker industrialist Ignaz Bing. In 1935 the company began producing the electrically powered model trains that it became famous for, under the Trix Express label. Prior to the outbreak of World War II the Trix company produced a small range of fairly unrealistic AC powered three rail models running at 14 volts.

N gauge models under the Minitrix brand were made from the late 1960s mostly of European prototypes (German and British primarily). North American prototypes were also manufactured and marketed under the Aurora "Postage Stamp" brand; later these items were sold under the American Tortoise, Model Power and Con-Cor brands. Trix sometimes utilized North American consultants to aid in the design of this portion of the product line. The "Hornby Minitrix' brand was used in the 1980s for a short lived range of British outline models using the earlier product tooling.

Trix's owner in the 1980s and 1990s was Mangold, which went bankrupt in the late 1990s and Märklin purchased the assets in January 1997. In part, this purchase was a reflection of Märklin's need for added production capacity; Trix had been manufacturing certain items for Märklin in previous years. The purchase was also in response to the earlier purchase of the Karl Arnold company by the Italian company Rivarossi; Märklin were very keen to take over Trix market share in 2-rail H0 and especially Minitrix, until then Märklin had not marketed N gauge models. In 2003, Märklin introduced its first N gauge models under the well established Minitrix brand. A number Märklin H0 scale three-rail AC locomotives have also been introduced in two-rail DC versions under the Trix logo and many models are shared between the two brands.

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.
