Structure and topology of high-speed rail networks Available to Purchase

Transport infrastructures, including high-speed rail networks, are built to make efficient transport services possible. An analysis of the characteristics of the networks and sections they comprise can support design decisions and contribute to increase the efficiency of transport services. This paper is devoted to analysis of the structure and topology of three representative high-speed rail networks, in Japan, France and Spain. The Japanese network presents a mixed lineal and branching structure, while the French and Spanish networks are clearly branching. The efficiency and ratios of development of the systems are estimated. Two types of sections can be differentiated in branching railway networks – those located in the centre, denoted as backbone sections, and their ramifications at the periphery. The operating models and line equipment used on these two types of sections should not be the same as their roles are different.
