Summary Very few passengers suffer from motion sickness on conventional trains and high-speed trains. Nevertheless, field tests carried out between Paris and Toulouse on a tilting train showed some sickness among passengers. Up to now, the standardised motion sickness index has been mainly developed for shipping and only takes into account the vertical motion experienced by passengers. This index did not correlate with motion sickness incidence during two field tests realised in tilting trains conducted during 1998 and 2000. Therefore, a railway motion sickness index is required to predict the lack of comfort likely to be experienced by passengers in tilting trains. In the future, this motion sickness index could be used to specify and to optimise the settings of tilting systems. This paper presents the latest laboratory tests realised in collaboration between SNCF and the University of Southampton (Institute of Sound and Vibration Research). The goal of these tests is to characterise on human subjects the influence of combined lateral and roll motions. A new simulator has been created to conduct the studies.
