These are made up of single diaphragms is riveted a >s-in. plate, 12 in. wide, which extends 54-in. pressed steel diaphragms and fillers to the top and bottom across the undername and forms part of the end sill. flanges of which are riveted cover plates 7 in. wide.

It hasbeen found from experience in service that with this construc-tion it is possible to support the center sill structure from theside sill girders so as to maintain the initial camber of 34-in. atthe center of the car, the trucks being 56 ft. 6 in. apart betweencenters.Pressed steel channels 3/16 in. thick secured at the ends to , , 7 Oyer fares. 3 Ply Salamana ^/layer of Heavy Waterproof Tamper g , 0± A Cross-Section of the Dining Cars the center and side sills, serve as additional transverse floorsupports. Intermediate longitudinal floor supports of 3-in., 6.7-lb. Z-bar sections are placed between the center sills and sidegirder construction. Each corner of the underframe is braced diagonally from thecorner to the intersection of the bolster and center sill by a 6-in., 10.5-lb. channel, placed with the flanges down. The platformend sill is an 8-in., 34-lb. H-beam, carefully fitted and attachedto the end of the center sills by means of two 6-in. by 3-in. by V%-. angle corner plates at each sill. The vestibule bumpersare U-sections pressed from 54-in. plate. They are secured tothe backs of the 9-in. 28.6-lb. ship channel vestibule end posts, the lower ends of which form a part of the platform construc-tion.
