Some stylized facts about high-speed rail: A review of HSR experiences around the world

After collecting information on 166 high-speed rail (HSR) projects across the world, this paper examines some of the most relevant empirical issues related to the implementation of this transport technology in recent years. We firstly discuss the economic definition of HSR, trying to identify its different development and operating models. Then, we provide what could be considered as a range of actual cost values of building and maintaining a high-speed rail infrastructure. A similar analysis is carried out regarding the operating and maintenance costs of high-speed rail services. Some information on external costs is also provided. We finally deal with current demand and its projections, and try to draw some inferences about its future evolution.
