Thrall Car Manufacturing Company

Thrall Car Manufacturing Company was a manufacturer of railroad freight cars in Chicago Heights, Illinois from 1917 to 2001. The company was sold to Trinity Industries in 2001.

A.J. Thrall established the Union Wagon Company in 1916, selling used and reconditioned rail car components. This became the Thrall Car Manufacturing Company in 1917. By mid-century, under the leadership of Richard L. Duchossois, the company focused on building specialized freight cars, such as high-cube boxcars for auto parts, all-door boxcars for building products, gondolas, rotary-dump gondolas for coal, bulkhead flatcars and centerbeam flatcars for lumber, double-stack container cars, covered hoppers, autorack cars and single-level trailer cars. In the 1980s, Thrall acquired five competing railcar manufacturers, including autorack builders Whitehead & Kales and Portec, and became the largest such manufacturer of these cars in the United States. In 1984, Duchossois purchased the remaining shares of the company owned by the Thrall family, and the company then operated as part of Duchossois Industries. In the 1990s, Thrall had a production capacity of over 16,000 freight cars per year, with more than 3,000 employees.
