A self-steering railway truck having interconnected steering arms associated with the axled wheelsets and having mechanism for yieldingly resisting yawing motion of the wheelsets including at least two devices, at least one of which provides a relatively high rate of increase of resistance per unit of deflection in the initial portion of the yaw motion and at least another of which provides a relatively low rate of increase of resistance per unit of deflection in a portion of the motion beyond the initial portion.
