Athearn - 11972 - Open Hopper, 3-Bay Steel - Detroit & Mackinac - 5 Different Numbers

Specific Item Information: N RTR 40 foot 3-Bay Rib Hopper w/Load, D&M #2 (5)

Prototype History: The 1960s brought about a growth in car size (and capacity). Railroads that transported coal moved away from the older 2-bay 55-ton USRA standard to newer 90- and 100-ton three bay hoppers. These cars were effective and long-lived. Many railroads swapped out the trucks on these cars to increase the capacity to 100 tons. Many companies produced these, including Pullman, Bethlehem, Evans, Greenville, Trinity and Ortner. The offset side variant of these hoppers carried a little more capacity than their rib-sided cousins.

Road Name History: First of all, Mackinac is pronounced “MACKinaw.” The Mackinac region is where Lake Superior and Lake Huron meet. Some towns in the region spell it with a W but not the D&M.

The D&M was established in 1894 as part of the reorganization of the Detroit Bay City & Alpena Railroad. The D&M ran from Cheboygan to Bay City and La Rocque plus branches, all in Michigan’s lower peninsula. The total mileage was 348, making it nearly as big as cross-lake neighbor Duluth Missabe & Iron Range. D&M had picked up some former Penn Central lines excluded from Conrail but service ended in 1990 on those routes. Traffic was primarily forest products and aggregates. In addition to connections on the southern end of the D&M, they interchanged with the Duluth South Shore & Atlantic (later SOO) on the Upper Peninsula via car ferry from Bay City across the Straights of Mackinac.

D&M’s diesel roster (around 12 units) was almost entirely Alco. They also had about 1200 freight cars. Their logo had a cartoon of an engineer named Mackinac Mac holding a wrench. The Detroit & Mackinac flag fell in 1992 when the owners sold it to a new railroad, Lake State Railway.

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.
