DELAWARE & HUDSON STEEL UNDER-FRAME FOR WOOD FREIGHT CARS In rebuilding and repairing cars of 60,000 lb. capacityof the box and single-hopper bottom type, and also fortandem hopper cars of 85,000 lb. capacity, the Delaware& Hudson is applying the steel underframe .shown in theaccompanying illustration. For the box cars, the underframe of which is shown in thedrawing, the steel portion consists of the center sills and thebody bolsters. The wooden end and side sills are retained andthe latter are trussed in the usual manner. The steel portionof the underframing includes the center sills, body bolsterand cross bearers for carrying the side sills. The centersills are formed of 12 in. channels. On top of these chan-nels there is a cover plate J4 in- thick extending from end bearers are of the same design except that but one sectionis used instead of two; this being stiffened with a coverplate at the top and bottom.
