High Speed Rail
High-speed rail (HSR) is a type of passenger rail transport that operates significantly faster than the normal speed of rail traffic. Specific definitions include 200 km/h (120 mph) for upgraded track and 250 km/h (160 mph) or faster for new track by the European Union. In Japan Shinkansen lines run at speeds in excess of 260 km/h (160 mph) and are built using standard gauge track with no at-grade crossings. In China, high-speed conventional rail lines operate at top speeds of 350 km/h (220 mph), and one maglev line reaches speeds of 430 km/h (270 mph).
