Container Car, Articulated Well, Thrall Lo-Pac

History: Gunderson cars were selling like crazy. So well in fact that Gunderson couldn't keep up with the orders. Thrall wanted in on the business, but couldn't use Gunderson's proprietary design, so they came up with their LoPac 2000 low sided container car. The distinctive rib sides of the Thrall are a ready spotting feature that Thrall cars carry to this day. The Thrall cars were designed to take a 40 foot container in the bottom and a forty footer on top. Some of the cars were equipped with hard points to attach 2 20 footers in each well. All were able to carry a 40, 45, or 48 foot container in the upper position, once the use of IBC's (Inter Box Connectors) became common practice.

The LoPacs were contemporaries of the Twinstack, and sales efforts between the two companies were fevered. The Thrall group reached the lucrative APL company with their car, and snagged a number of sales. They made two distinct versions of the car for APL, and then sold them to other entities. The first was a "normal" well car for use with dry box containers. The second version was a powered version specifically designed to carry reefers. The car was colored red and a generator was mounted at one end. Extension cords were strung from the generator to each individual container to provide power to the reefer units mounted there. The Thrall braking arrangement on this car is the same as the Gunderson on the twinstack- one brakewheel at the B end. In later versions, there is a brakewheel painted orange at both the A and the B end. This arrangement indicates the longer 48 foot wells and dual braking system installed on the more recent production. Thrall has remained a force in Intermodal railroading with their more recent all purpose well car, continued 5 unit production, and many many spine cars. Their most recent product in the intermodal world is a three unit car capable of carrying 53 foot containers in the upper and lower positions of each well.

Railroad/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.

From 1997, a European subsidiary Thrall Europa manufactured wagons in York, UK. Thrall Europa, York works closed 2002. In 2000, Thrall Europa acquired the railway vehicle manufacturer ČKD Vagonka Studénka (Czech Republic), renamed Thrall Vagonka Studénka. In 2006 Trinity Industries sold off its European operations to International Railway Systems. The closely held company was sold to Trinity Industries, based in Dallas, Texas, in 2001. The company was subsequently renamed Trinity Rail Group, LLC.
