The US FDA’s proposed rule on laboratory-developed tests: Impacts on clinical laboratory testing
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 200 km/h (120 mph), which is the world's first high-speed rail. Various definitions are used in different countries.
According to the European Union, high-speed trains must run at least 200 km/h (120 mph) on existing lines, and at least 250 km/h (160 mph) on newly built ones.
According to the United States Federal Railroad Administration, they should go above 90 mph (140 km/h) but there is no single standard, and lower speeds can be required by local constraints.[1][2]
As of 2020, speeds of 300 km/h (190 mph) to 350 km/h (220 mph) are common in regular operation.[source?]
