The conflict between stability and curving has been well documented since the dawn
of the railways. Advances in computer technology and deeper understanding of the
complex mechanics of the wheel-rail interface have led to the study of innovative
designs. This thesis outlines the need for steering systems for railway applications.
A number of innovative passive solutions have been proposed to reduce the conflict
between stability and curving. Comparisons of some of these solutions show that
significant benefits can be obtained by using uncommon configurations. [Continues.
