Lumber has always been difficult to ship by rail. Box cars provide protection but are hard to load and unload. Flat cars eliminate those problems, but loads have to be tarped to protect them from the weather. In 1967, Thrall created the All-Door Box Car. Equipped with four large doors, this provided a 25' 7.5m opening for easy handling, while loads remained completely enclosed in transit. Our ready-to-run cars are packed with detail and painted for a variety of private owners. Free-rolling trucks and working knuckle couplers are standard equipment.
