Atlas - 50 000 202 - Covered Hopper, 4-Bay, ACF Centerflow - Dow - 2131

Specific Item Information: The model depicted here is the HO version.
The photo for this model depicts another model identical in all respects except the reporting number.

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 Dow Chemical Company (NYSE: DOW), commonly referred to as Dow, is a multinational chemical corporation headquartered in Midland, Michigan. Dow provides chemical, plastic, and agricultural products and services to consumer markets that include food, transportation, health and medicine, personal care and construction, and operates in approximately 180 countries.

As of 2014, Dow ranked third in chemical production (after BASF and Sinopec), and as of 2015, was the third largest chemical company in the world by revenue (after Sinopec and BASF). Dow was also the world's largest chlorine producer, with 5.7 billion tons a year of production before Dow's association with Olin was formed; was ranked as the world's largest plastics manufacturer during 2008, and the largest manufacturer of polyalkylene glycols in 2013.

Dow's principal lines of business include Agricultural Sciences, Consumer Solutions, Infrastructure Solutions, Performance Materials & Chemicals, and Performance Plastics. It employs approximately 53,000 people worldwide. Dow's 2014 sales totaled approximately $58.2 billion. Dow has been called the "chemical companies' chemical company" in that most of its sales are to other industries rather than end users, although Dow sells directly to end users primarily in the human and animal health, agriculture, and consumer products markets.

The company was founded in 1897 by Canadian-born chemist Herbert Henry Dow. After a period of diversification, it became a major chemical company, a significant player in the world market, and a part of the military-industrial war effort during both World Wars.

Brand/Importer Information: In 1924 Stephan Schaffan, Sr. founded the Atlas Tool Company in Newark, New Jersey. In 1933 his son, Stephan Schaffan, Jr., came to work for his father at the age of sixteen. Steve Jr. built model airplanes as a hobby and frequented a local hobby shop. Being an enterprising young man, he would often ask the owner if there was anything he could do to earn some extra spending money. Tired of listening to his requests, the hobby-store owner threw some model railroad track parts his way and said, "Here, see if you can improve on this".

In those days, railroad modelers had to assemble and build everything from scratch. Steve Jr. created a "switch kit" which sold so well, that the entire family worked on them in the basement at night, while doing business as usual in the machine shop during the day.

Subsequently, Steve Jr. engineered the stapling of rail to fiber track, along with inventing the first practical rail joiner and pre-assembled turnouts and flexible track. All of these products, and more, helped to popularize model railroading and assisted in the creation of a mass-market hobby. The budding entrepreneur quickly outgrew the limitations of a basement and small garage operation. Realizing they could actually make a living selling track and related products, Steve and his father had the first factory built in Hillside, New Jersey at 413 Florence Avenue in 1947. On September 30, 1949, the Atlas Tool Company was officially incorporated as a New Jersey company.

In 1985, Steve was honored posthumously for his inventions by the Model Railroad Industry Association and was inducted into the Model Railroad Industry Hall of Fame in Baltimore, Maryland. In addition, Steve was nominated and entered into the National Model Railroad Association Pioneers of Model Railroading in 1995.

In the early 1990s, the Atlas Tool Company changed its name to Atlas Model Railroad Company, Inc.
