High-speed rail (HSR) is a type of passenger rail transport that operates significantly faster than the normal speed of rail traffic. Specific definitions by the European Union include 200 km/h (124 mph) for upgraded track and 250 km/h (155 mph) or faster for new track,whilst in the United States, the U.S. Department of Transportation defines it as “reasonably expected to reach sustained speeds of more than 125 mph (201 km/h),” although the Federal Railroad Administration uses a definition of above 110 mph (177 km/h) [source].
