Standard Caboose Car Design Recommended by the Railroad Administra-tion; Strong Underframe for Heavy Pusher Service THE REQUIREMENTS of the laws of the various states inthis country regarding railway caboose cars make itvery desirable that a standard design be adopted forthe construction of this class of car. To meet this need theUnited States Railroad Administration has issued an ap-proved standard design for such cars. It is not proposedto require that cars must be built to these drawings, but to railroads. This article shows the 24 ft. caboose recommendedby the Railroad Administration for the future construction ofcars of this class. THE SUPERSTRUCTURE The body framing is built up of 3-in. by 3-in. by , the side and end posts being adequately braced by. 104 Om-SirMni/Phfc Side Elevation of U. S. R. A.

The proposed design is a 24-ft. caboose of the com-posite type, having a steel underframe and superstructure,with wood outside sheathing and interior finish. angles of the same size and with gussets of 54-in. steelplate securely riveted at the side sills and top plates and atintermediate points on the side posts.
