The new design, known as the Class11-24 car, is patterned after their quad-ruple hopper car. Class H-21/A, the de-tails of which are interchangeable with it. increa>cd volume is obtained by anadditional bay, 6 ft. 4 ins. long, thus pro-viding for live hoppers instead of top and bottom members of thesides of the 11-24 have been increasedSO per cent, in area over that of theH-21/A, to take care of the additionalload. The underframe is characteristic offormer P. R. R. designs, having a well-balanced central member to absorb thebuffing stresses, while the major portionof the load is carried by the side con-struction. The backbone of the car is. \TV-TOX GOXof separate pieces ot pressed steel or struc-tural sections riveted thereto, and in ad-dition a door spreader was connected withadjacent doors for the purpose of openingand closing them. The present construc-tion obviates the necessity of using aseparate stiffener, but the door spreaderitself serves as a stiffener and spreadercombined, and is attached directly to thedoors, the side flanges of the doors beingbent upwardly so that this can be done. This construction materially reducesweight and cost of each car, and at thesame time makes the work of buildingthem more simple than previously. Thisparticular detail, that is, the arrangementof the doors and the spreaders in connec-tion with them, was designed by Mr. RalphV. Sage, Contracting Car and Structuralengineer and Mr. Ralph E. Wilder, carengineer of the Cambria Steel Company, nOLA FOR THE P. R. R. BY T
