Gondola, Bathtub, Trinity Rotary

History: There have been a number of designs of coal-hauling gondolas for todays operations. Most of the major builders have offered aluminum-bodied coal gons at one point or another. Bethlehem Steel Car made a significant introduction with its Bethgon design. This design continues with Johnstown America today. The basic design uses two longitudinal tubs between the trucks - thus adding additional cubic-foot capacity with a lower center of gravity.

In 1992, Trinity Industries introduced a similar design and called it the Aluminator. Six demonstrators were built and placed under Trinity Industries Leasing Company reporting marks (TIMX 1001-1006). This initial design was rated at a 4,400 cubic-foot capacity. Most new-built coal cars (hoppers and gondolas) are built to a standardized 53' 1" outside length. The Trinity Aluminator is no exception. The 4400 design has a 12' 7" extreme height (11' 6" inside height). What made the Aluminator unique was the way the bottom of the tubs slope down ward from the center to the ends (the Bethlehem/Johnstown design had straight bottom tubs). The body has 13 side posts each with an alternating rivet pattern. There are three internal cross braces (at the 4th, 7th and 10th side posts). Trinity's aluminum rotary dump gondola features twin longitudinal tubs located on either side of the steel center sill.

Railroad/Company: 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.
