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. These are the cars that BLI is delivering 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.
