ABSTRACT:
A railway vehicle truck has a rigid frame spring-supported at the ends of the frame side members on the journal boxes inboard of the wheels, with the central portion of the frame side members depressed to a lower level than the ends. A pair of center transoms are formed with extensions upwardly and outwardly of the side members adjacent the depressed center portions thereof, the outer extremities of the extensions being positioned outwardly of the wheels and pivotally supporting depending swing hangers. A spring plank supported from the lower ends of the swing hangers extends transversely of the truck through apertures in the depressed center portions of the frame side members, and springs carried by the outer ends of the spring planks support the ends of a bolster which extends outwardly over the frame side members. Longitudinally extending bolster anchors connect each end of the bolster to the corresponding side of the truck frame and a transversely extending spring plank anchor connects the spring plank and the bolster.
