Abstract
A dual lading railroad car which can carry solid, granular lading in hoppers at each end of the car and a liquid lading in a tank located in the center of the car between the hoppers. Only liquid lading can be carried in one direction and only solid, granular lading can be carried in a different or return direction, or both such ladings can be carried simultaneously in the same direction. Phosphate rock can be carried in the hoppers and molten sulfur in the tank. The exterior of the car looks substantially like a conventional covered hopper car since the tank is fully enclosed by the car walls and roof.
