Trinity Industries, the nation's largest railcar manufacturer and a leading builder of inland barges, highway guardrails and metal components, has a fascinating history of growth through diversification and strategic acquisitions. The company grew from a small household butane and propane gas tank manufacturer to become a $2.5 billion global giant. Trinity has acquired the assets of more than 100 companies, including the venerable Pullman Standard Company, manufacturer of passenger railcars. The Legend of Trinity Industries, by industrial historian Jeffrey L. Rodengen, recounts the determination and corporate strategy that have propelled Trinity to the leadership role of its industry.
