Modified railway passenger truck designs are considered to improve the comp
atibility between dynamic stability and the ability of the vehicle to steer
around curves, A comparative study on the non-linear steady-state curving
behavior of some unconventional truck designs reveals that a modified truck
design in which the primary suspension in the leading axle is different fr
om the trailing axle - known as the unsymmetrical suspension truck - has th
e potential to achieve overall superior performance compared to other truck
models considered in this paper. (C) 2001 Elsevier Science Ltd. All rights
