Express refrigerator cars were used to carry perishable crops like berries and melons to distant markets at passenger train speeds before spoilage could occur. Normally, they were operated at the head end of passenger trains, which required that the cars meet the same design standards as steel postal cars in terms of high speed trucks, passenger car brake systems, air, steam and signal lines, passenger car buffers as well as passenger paint and lettering schemes. The General American 53?-6" wood express refrigerator cars were the most common cars used in the U.S. during the 30?s, 40?s and 50?s, and were painted and lettered for a variety of Class I railroads. And these are the cars that BLI will be offering in the Fall of 2004 in single packs and double packs. The car numbers will all be different in the two packages. All hand grabs will be applied and painted at the factory.
