Athearn - 27437 - Covered Hopper, 3-Bay, PS-2-CD 4427 - Burlington Northern - 450868

Model Information: Pullman-Standard dominated the covered hopper car market beginning in the 1950s, thanks to the design success of their PS-2 series of covered hoppers. In 1964 the 4427 cubic foot capacity covered hoppers were introduced. PS responded to increasing demand for efficiency by the railroads and shippers alike, carrying more per trip then the 40’ boxcars with the signode grain door. Designed to carry bulk commodities, such as grain, these cars roamed the rails of North America for decades, attesting to their utilitarian functionality. These cars can still be seen today in service.

Prototype 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.
Over 19,300 PS2-CD 4,427 cars were produced.

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.

Road Name History: The Burlington Northern Railroad (reporting mark BN) was a United States railroad. It was a product of a March 2, 1970, merger of four major railroads - the Great Northern Railway, Northern Pacific Railway, Spokane, Portland and Seattle Railway and the Chicago, Burlington and Quincy Railroad - as well as a few small jointly owned subsidiaries owned by the four.

Burlington Northern operated between 1970 and 1996.

Its historical lineage begins in the earliest days of railroading with the chartering in 1848 of the Chicago and Aurora Railroad, a direct ancestor line of the Chicago, Burlington and Quincy Railroad, which lends Burlington to the names of various merger-produced successors.

Burlington Northern purchased the Atchison, Topeka and Santa Fe Railway on December 31, 1996 to form the Burlington Northern and Santa Fe Railway (later renamed BNSF Railway), which was owned by the Burlington Northern Santa Fe Corporation.*

Brand/Importer Information: Athearn's history began in 1938, when its founder-to-be, Irvin Athearn, started an elaborate O scale layout in his mother's house. After placing an ad selling the layout, and receiving much response to it, Irv decided that selling model railroads would be a good living. He sold train products out of his mother's house through most of the 1940s. After becoming a full-time retailer in 1946, Irv opened a separate facility in Hawthorne, California in 1948, and that same year he branched into HO scale models for the first time.

Athearn acquired the Globe Models product line and improved upon it, introducing a comprehensive array of locomotive, passenger and freight car models. Improvements included all-wheel drive and electrical contact. One innovation was the "Hi-Fi" drive mechanism, employing small rubber bands to transfer motion from the motor spindle to the axles. Another was the double-ended ring magnet motor, which permitted easy connection to all-wheel-drive assemblies. Athearn was also able to incorporate flywheels into double-ended drives.

The company produced a model of the Boston & Maine P4 class Pacific steam locomotive which incorporated a cast zinc alloy base and thermoplastic resin superstructure. It had a worm drive and all power pickup was through the bipolar trucks that carried the tender. This item was discontinued after the Wilson motor was no longer available, and was not redesigned for a more technologically advanced motor.

Athearn's car fleet included shorter-than-scale interpretations of passenger cars of Southern Pacific and Atchison, Topeka & Santa Fe Railroad prototypes. The company also offered a variety of scale-length freight cars with sprung and equalized trucks. The cars could be obtained in simple kit form, or ready-to-run in windowed display boxes. The comprehensive scope of the product line contributed to the popularity of HO as a model railroad scale, due to the ready availability of items and their low cost.

Irv Athearn died in 1991. New owners took control in 1994, but continued to follow Athearn's commitment to high-quality products at reasonable prices. Athearn was bought in 2004 by Horizon Hobby. Athearn was then moved from its facility in Compton to a new facility in Carson, California. In mid-2009, all remaining US production was moved to China and warehousing moved to parent Horizon Hobby. Sales and product development was relocated to a smaller facility in Long Beach, California.
