High-speed rail (HSR) is a type of rail transport network utilizing trains that run significantly faster than those of traditional rail, using an integrated system of specialized rolling stock and dedicated tracks. While there is no single definition or standard that applies worldwide, lines built to handle speeds of at least 250 km/h (155 mph) or upgraded lines of at least 200 km/h (125 mph) are generally considered to be high-speed.
