High-speed rail is a type of passenger rail transport that operates significantly faster than the normal rail traffic. Early Shinkansen trains had a top speed of 200km/h. Various definitions are used in different contries.
According to the European Union, high-speed trains must run at least 200km/h (125 mph) on existing lines, and at least 250 kilometres per hour (160 mph) on newly built ones.
As of 2020, speeds of 300 to 350 km/h are common in regular operation.
