Chapter 11: High-Speed Rail

High-speed rail, as a distinct subset of rail systems, has been in operation since 1964, first introduced in Japan and subsequently adopted widely in heavily populated countries across Europe and Asia with plans in place to extend to America and Australia. Development of technologies has been continuous such that maximum speed in service operation has safely increased from 210 to 350 km/h with further advances to come in the next decade. Its economic and social effect through reducing journey time between cities while also offering very high capacity, reliability and safety with a low-carbon footprint means it is no longer considered by sponsoring governments on its merits as a transport system but rather as part of a wider set of strategic policies around housing settlement and employment. Analysis techniques continue to be developed to estimate true benefits alongside construction, environmental impact and operational costs.
