A\hen tlie doors are closed they are supportedonly at the ends, the edges of the doors being reinforced byangle irons of sufficient stiffness to support the load betweenthe sides of the car. The ends of these angles project slightlybe\ond the sides of the car, where they engage the hookswhich hold the doors closed. The door locking device issimple in construction. It is manufactured by the Wine to the side frame me
