These conditions weremade possible without reducing materially the carrying capacityby increasing both the height and the width of the cars, reduc-ing the wheel base of the trucks and spreading the trucks furtherapart from center to center. The door opening is closed by twodoors hinged at the sides, which form part of the vertical sides,so that when opened, part of the .sides, as well as the bottom, fallsaway from the load, thus making a large unobstructed opening,and reducing the chance of bridging to a minimum. The doorsmeet on the center line of the car and each are supported by twosix inch channel bars, to which the door operating gear bars
