At increased rail vehicle speed it may be difﬁcult to maintain acceptable passenger ride comfort with conventional passive secondary suspension. This paper presents the development of an active secondary suspension that provides good ride comfort improvements, but still at an acceptable cost level to enable future implementation. On-track tests have been performed with a two-car Regina train, using electro-hydraulic actuators together with sky-hook damping control and a Hold-Off-Device function to actively control the secondary suspension. The evaluated measurement results show that the active suspension system signiﬁcantly reduces the lateral dynamic carbody motions and the lateral quasi-static displacements between carbody and bogies in curves, which improves the ride comfort and allows higher speeds, particularly in curves.
