Book excerpt: The European railway sector has undergone profound and predominantly institutional changes over the past 20 years, due to the initiatives of the European Commission. This book constitutes a first systematic assessment and account of the recent transformations of the industry along a series of critical yet contentious issues such as competition, unbundling, regulation, access charging, standards and interoperability, and public–private partnerships. It also covers the main railways sectors including passenger transport, high speed and freight.
