Knowra High-speed rail High-speed rail High-speed rail is passenger rail service operating substantially faster than conventional rail, typically on dedicated or upgraded tracks. Its performance depends on trains, infrastructure, and operating systems designed to work together.
Dedicated high-speed railway : A railway built primarily for high-speed passenger trains, with alignment and infrastructure designed for sustained high speeds. Separate tracks let services avoid slower trains and use geometry suited to fast running.
Shinkansen : Japan's high-speed rail network, inaugurated in 1964 and known for frequent, fast intercity service. Its operation demonstrates how dedicated infrastructure can support dense passenger service.
Conventional rail : Passenger or freight rail operating on infrastructure not designed for the highest rail speeds. It provides the baseline against which high-speed rail's speed and infrastructure needs are judged.
Cost–benefit analysis : A method for comparing a project's expected social benefits with its costs. High-speed projects require weighing travel-time savings against construction and operating costs.
Hideo Shima : A Japanese railway engineer who led the technical development of the original Tōkaidō Shinkansen. His engineering leadership helped turn Japan's first high-speed line into an operating system.
High-speed train : A passenger train engineered for stable, efficient operation at high speeds. Train shape, power, braking, and suspension must match the demands of fast service.
TGV : France's high-speed train system, introduced in 1981 and operated on purpose-built lines and conventional tracks. Its mixed network illustrates how high-speed trains can extend beyond dedicated corridors.
High-speed rail versus air transport : A comparison of rail and air travel by journey time, cost, capacity, access, and environmental impact. The modes compete most directly on medium-distance city pairs with frequent service.
Induced demand : An increase in travel caused by expanded transport capacity or reduced travel costs. New fast connections can generate trips as well as shift existing ones between modes.
Tōkaidō Shinkansen : Japan's first Shinkansen line, opened in 1964 between Tokyo and Osaka. Its launch established a widely studied model for high-speed passenger railway service.
