Athearn - 23994 - Covered Hopper, 2-Bay, GATX Airslide 2600 - SOO Line - 69262

Model Information: This is a really impressive model with a surprising array of detail. It is a proper 3rd generation model with body-mount couplers, chemically blackened metal wheels and an array of amazing detail parts. The details include an etched metal roofwalk, hatch covers, and an underframe with at least six different separately applied details. And don't forget the end platform detail - it blows away the Atlas model. Too bad they use McHenry couplers.... I would prefer to see MTL or MTL-knockoff couplers.

This Athearn body style comes in three different variations. (1) Early GATC Airslide body: no angled end gusset plates; channel-section vertical posts at bolsters. (2) Intermediate phase I body: "Hat Section" vertical posts at bolsters; angled gusset plates at ends. All variations feature: Detailed underbody including outlet piping; Rectangular or oval shaker brackets; Gravity or gravity-pneumatic outlets; See through metal roof walk; Factory installed wire grab irons and brake piping; Separately applied round roof hatches and brake wheel; Roller bearing or Bettendorf trucks as appropriate; Accurately painted and printed; Highly detailed, injection molded body; Machined metal wheels; Weighted for trouble free operation; Body mounted McHenry operating scale knuckle couplers; Minimum radius: 9 3/4".

Prototype History: The airslide covered hopper was introduced by General American Transportation Corporation (GATX) in 1953. Approx. 5000 of the 2600 cu. ft. cars were built between that year and 1969. The airslide is primarily designed for the bulk shipment of dry, granular or powdered commodities. The design of that car is such that it can be loaded and unloaded quickly and with little spillage through the use of air pressure. The most common commodities carried include: flour, sugar, starch, plastic pellets, cement, powdered chemicals and carbon black.

he Airslide was first patented in 1953, the same year Pullman Standard introduced their PS-2. What made the car unique was a set of fabric membranes in the hopper bays. Made of tightly woven cotton and treated with silicone, the Airslide® membranes were moisture-proof but allowed air to pass through. Compressed air was supplied at the unloading site and passed through the membrane up into the load. This aerated the load, allowing it to flow easily through the hoppers.

Road Name History: The Soo Line Railroad (reporting mark SOO) is the primary United States railroad subsidiary of the Canadian Pacific Railway (CP), controlled through the Soo Line Corporation, and one of seven U.S. Class I railroads. Although it is named for the Minneapolis, St. Paul and Sault Ste. Marie Railroad (MStP&SSM), which was commonly known as the Soo Line after the phonetic spelling of Sault, it was formed in 1961 by the consolidation of that company with two other CP subsidiaries, the Duluth, South Shore and Atlantic Railroad and Wisconsin Central Railroad. It is also the successor to other Class I railroads, including the Minneapolis, Northfield and Southern Railway (acquired 1982) and Chicago, Milwaukee, St. Paul and Pacific Railroad (Milwaukee Road, acquired at bankruptcy in 1985). On the other hand, a large amount of mileage was spun off in 1987 to Wisconsin Central Ltd., now part of the Canadian National Railway.

The Soo Line and the Delaware and Hudson Railway, the CP's other major subsidiary (before the 2008 DM&E acquisition), presently do business as the Canadian Pacific Railway, and most equipment has been repainted into the CP's scheme, but the U.S. Surface Transportation Board groups all CP's U.S. subsidiaries under the Soo Line name for reporting purposes.

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.
