Modified railway passenger truck designs are considered to improve the compatibility between dynamic stability and the ability of the vehicle to steer around curves. A comparative study on the non-linear state curving behaviour of some unconventional truck designs is carried out. The study reveals that modified truck designs with primary yaw dampers improve the performance. A particular design of railway truck in which the rear axle is an independent wheelset and in which the primary suspension in the leading axle is different from the trailing axle - known as the unsymmetric wheeelset and suspension truck - has the potential to achieve overall superior performance compared with other truck models considered in this paper, for design speeds of around 80 m/s. For the lower design speed of around 60 m/s, a conventional truck provided with primary yaw damper achieves adequate performance and is recommended for its simpler design features.
