Prototype History: Liquefied Petroleum Gas (LPG) (also called Autogas) is a liquefied mixture of propane and butane. It is an inevitable by-product of the crude oil refining process and of natural gas processing. In natural gas processing, the natural gas is cleaned off heavy hydrocarbons such as propane and butane before distribution. About 60% of global LP Gas supply comes from natural gas processing. In crude oil refining, LPG is a by-product of the refining process. LPG is gaseous at room temperature and changes to a liquid when compressed at moderate pressure or chilled. The chemical composition of LPG can vary, but is usually made up of butane and propane with a 30-99% propane mix.

The 33,900 gallon tank car is one of the largest standard tank cars used today. While Liquefied Petroleum Gas (LPG) and Anhydrous Ammonia are the two most common commodities, they are also used to transport butadiene, isoprene and gasoline. These cars can be seen regularly in mixed manifest freight trains throughout North America. They travel singly or in large blocks between producers and distributors.

Road Name History: The company, first known as Trinity Steel, was founded by C. J. Bender in Dallas in 1933. W. Ray Wallace, an engineering graduate of Louisiana Tech, worked for Dallas's Austin Bridge Company in 1944 before joining the company in 1946 as its seventeenth employee. At the time Trinity Steel manufactured butane tanks in a Dallas County mule barn. In 1958 Trinity Steel merged with Dallas Tank Company, which was also founded in 1933, and Ray Wallace became the new firm's president and first chief executive officer. At the time Trinity had revenues reaching $2.5 million and employed 200 workers. While some employees of the firm in other states eventually unionized, Texas workers never formed a union. For a time the company profited by producing larger tanks that enabled it to enter the petroleum business and do steel fabrication for refineries. In addition, to free up capital, it established an investment company to buy trucks and lease them back to the firm. Nonetheless, by 1957 Trinity faced competition and declines in the petroleum industry. Dallas Tank, Trinity Steel, and Bender-Wallace Development Company merged in 1958 to form Trinity Industries, Incorporated, and went public.

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.
