This paper presents hunting stability and curving performance of high speed rail vehicles. Considering non-linear creep force and flange contact, the lateral force of front wheel on outer rail was calculated in steady state curve negotiation, and critical speed of wheelset and truck hunting was also calculated. The influence of linkages which were so-called cross-anchor linkage, linkage between wheelset and truck frame, and secondary suspension which were bolster anchors and anti-yaw damper and primary anti-yaw damper were examined. These results were compared with our proposed analytical solutions of optimal design for stability and curving performance, and design of truck suspension was discussed. By studing the difference of analytical truck models, it was proved that it was possible to use half body model for testing on roller rig or truck model. Moreover calculation of hunting stability by using half body model was compared with results of test on roller rig, which was carried out in Railway Technical Research Institute with good agreement.
