History: Valued for its large capacity, roof trough hatches, and center discharge gates, the 4427 PS-2 CD High-Side Covered Hopper was a favorite for hauling grain. These large hoppers could be found across the continent hauling grain and other medium-density loads beginning in the 1960s, often in multi-car cuts or unit trains. Many are still seen in service during the fall harvest, 30 years after their construction.

Even with Pullman Standard Car Manufacturing Company's passenger car designs and patents spun off to a separate company called Pullman Technology in 1982 (which was eventually sold to Canadian based Bombardier in 1987) and Pullman Standard's remaining railcar manufacturing plants and freight car designs and patents sold to Trinity Industries in 1984, American manufactured Pullman freight and passenger cars were (and to this point in time still are) well known in North America.

When it came to hauling dry bulk goods such as agricultural commodities, cement, clay, dry chemicals, salt, or sand. many railroads and private owners selected the Pullman Standard PS-2 series covered hopper.
Utilized to transport dense and heavy granular products like cement, clay, potash, and sand, due to North American axle weight load limits, two (and later) three bay models were often chosen.
When it came to hauling much lighter commodities such as barley, corn, grain, malt, oats, soybeans, sugar, and wheat, these kinds of products would most commonly be transported in three or four bay covered hoppers.
Unlike two bay models, large four bay cars lend themselves to rapid load and discharge operations.

While there are a wide range of products covered by the PS-2 designation, it was Pullman's 4427 cubic foot capacity covered hopper that stood out as being the first of the larger capacity models to be manufactured in greater numbers.
Introduced as the PS-2CD (center discharge) in late 1963, the early production "low hip" design 4427 cubic foot capacity cars had low body sides, which concealed most of the hopper bay area.
The manufacturing of "high hip" design raised side 4427 models commenced in November 1966.

Visibly apparent are a few different body style variations.
With the latter style being the most popular choice, the top of the covered hoppers could be fitted with large trough style openings, or, a series of round ones.
With the latter position being most common, brake wheels could be positioned high up on the body end, or, low mounted.

Railroad/Company:
The Pullman Car Company, founded by George Pullman, manufactured railroad cars in the mid-to-late 19th century through the early decades of the 20th century, during the boom of railroads in the United States. Its workers initially lived in a planned worker community (or "company town") named Pullman, Chicago. Pullman developed the sleeping car, which carried his name into the 1980s. Pullman did not just manufacture the cars: he also operated them on most of the railroads in the United States, paying railroad companies to couple the cars to trains. The labor union associated with the company, the Brotherhood of Sleeping Car Porters, which was founded and organized by A. Philip Randolph, was one of the most powerful African-American political entities of the 20th century. The company also built thousands of streetcars and trolley buses for use in cities.
