This truck is shown in our half-tone,and also in line engraving. It is seenthat the whole frame is composed ofstandard rolled shapes. The side framesare made of is-inch I-beams, which are this hinged jaw, than can be done withthe arch-bar truck. If the steel truck isto become a permanent fixture, as we be-lieve it will, this improved jaw is one ofthe features that will insure its early adop-tion, and the adaptation of rolled shapesshould not retard such action, for the rea-son that the vital element of low cost isa strong factor in its favor. The tran-soms, which are made» of channels, andthe brake-beams are all seen to be procurable rolled Among the best of these is the produc-tion of Mr. G. R. Joughins, superinten-dent of motive power of the Norfolk &Southern Railroad, who was one of thefirst in the field of steel-car design, witha car which is still in service. It is but anatural and fitting sequence that he shouldhave devoted some thought to a steeltruck, after his experience with a steelcar, and was probably the first to proposea rolled-beam truck; it is certain, how-ever, that his is the first truck built ofrolled sections, and in use. THE JOUGHINS STEEL TUUCK—DETAILS. cut out at the ends and bent both waysto form the jaws; the latter are then rein-forced to receive the boxes and strong point of the truck is the hingedjaw which is pivoted and bolted at theouter end of the frame to facilitate theremoval of a pair of wheels. This improvement in trucks of this typeremoves a very serious objection^in fact,it has bee
