Since 2012, the UIC and the Rail Safety and Standards Board (RSSB) have worked together in partnership to develop and maintain SPARK for the benefit of the global railway community. In parallel, the UIC research portal,, provides information about rail research events, news about developments in R&D as well as information on special events such as Transport Research Arena (TRA), World Congress on Railway Research (WCRR)... etc.
