High-speed rail is a type of passenger rail transport that operates significantly faster than the normal speed of rail traffic. Specific definitions include 200 km/h
(125 mph) for upgraded track and 250 km/h
or faster for new track by the European Union, and above 90 mph (145 km/h
) by the United States Federal Railroad Administration, but there is no single standard, and lower speeds can be required by local constraints.....
The highest scheduled average speed between two scheduled stops is held by China Railway High-speed service on Wuhan-Guangzhou High-Speed Railway. Non-stop trains on this line cover the 922-km journey in 2 hours, 57 minutes, at an average speed of 312.5 km/h
from Wuhan to Guangzhou North. ....
