The problem of lateral stability of a six-axle locomotive is investigated. The linear equations of motion for a locomotive model with 21 degrees of freedom are derived. A linearized theoretical analysis is made which indicates the importance of various design parameters for high speed operation. Parameters found to have a significant effect on the critical speed for hunting oscillations are: truck wheel base, wheel tread taper angle, the lateral stiffness and amount of damping in the primary suspension, and the yaw moment of inertia of the wheel set and truck frame. Some limitations of the model are pointed out for future investigations.
