The Authors analyse the impact of the project “Rail Baltica” on the development of high-speed railways in Lithuania. The purpose of the research – to assess the need for high-speed railways and suggest the most rational operational model for high-speed railways in Lithuania. In developing the traffic of high-speed railways, many railway infrastructure managers are faced with the choice of rational operational model for train traffic. The Authors suggest solving this problem by applying Multi-Criteria Decision Making methods. In order to determine the compatibility of expert opinions the Kendall’s rank correlation method was used. As a result of this study, the Exclusive exploatation model for train traffic management was selected for Lithuanian Railways.
