Case Studies in Public–Private Partnership of High-Speed Railway Transport

European railway transportation is not as efficient as it could be. Public–private partnerships can yield higher efficiency in railway transport. There are a few implemented infrastructures through public–private partnerships and, in many of them, the result has not been the expected one. The purpose of this research is to develop a list of recommendations and good practices that allow governments, private investors, and railway stakeholders to take better and more efficient decisions on the implementation of new high-speed rail lines. Consequently, this research has analysed through seven case studies, all the high-speed lines designed through public–private partnerships in Europe. The research methodology is based on exploratory case study and on the identification of critical success factors. This article has made it possible to develop a list of recommendations and good practices.
