SWING MOTION RAILROAD TRUCK ABSTRACT OF THE DISCLOSURE A truck for a railroad car includes two spaced side frames which resiliently support ends of a transversely positioned bolster in a window formed in each side frame. On each side of the bolster is a vertical recess formed having opposing convex-shaped sides which engage with end walls of vertical ribs formed on an inner and outer side of spaced sidewalls of the side frame window In downwardly projecting pedestal jaws formed at each end of each side. frame and having selectively spaced sidewalls are journaled axle ends of a front and a rear wheelset. Interposed between each axle end and a roof of the pedestal jaw is a bearing adapter having a convex top surface to engage with a concave surface of the roof of the side frame pedestal jaw. During travel of the truck a relative rolling movement between the wheelsets, side frames and bolster may occur because of the interaction of the convex sides of the bolster recess with the ribs of the side frame, and because of a like interaction between the convex top surface of the adapter with the roof of the pedestal jaw. -i-
