The Stability of a Class of Multiaxle Railway Vehicles Possessing Perfect Steering

For railway vehicles having coned or profiled wheels mounted on solid axles there is conflict between the criteria for stability of lateral deviations from steady motion along the track and those for good steering performance. However, a certain class of multi-axle vehicle possesses perfect steering in which curves are negotiated without creep. The general theory of stability for such vehicles is developed and applied, by way of example, to the particular case of a three-axle vehicle having shear stiffness between all wheelsets.
