ABSTRACT:
A steerable railway truck includes a main frame structure having a bolster and a pair of side frames to be secured to a car body. A pair of "C" shaped sub-frames are interconnected. Extending arm portions of the sub-frames are slidably mounted to the end of the side frames on shear plate assemblies. Hanger elements extend from the main frame to hold the interconnected sections of the sub-frame. A steering link member is connected between the main frame and one of the sub-frames to force the two frames to steer when the car body moves over curved tracks.
