Abstract

A fully protective multi-unit railroad freight car for carrying motor vehicles on two or three levels with the lowest level being in a cargo well between a pair of deep side sills. A pair of vehicle-carrying decks are adjustable in height and are counterbalanced against each other during adjustment of their locations. A roof structure is light in weight and constructed of corrugated sheet metal with a self-supporting central portion. The ends of the car are equipped with three-panel folding doors, and a flexible diaphragm closes the space between articulated adjacent car units supported by a shared truck. A modular brake operating system is mounted on the car body.
