High-speed rail is a type of rail transport that operates significantly faster than traditional rail traffic, using an integrated system of specialized rolling stock and dedicated tracks. Generally, high-speed rail services operate at speeds of 200 km/h (124 mph) or higher, with some systems reaching speeds of up to 350 km/h (220 mph). High-speed rail systems offer an efficient and comfortable alternative to air and road travel, with shorter journey times, lower energy consumption and a smaller environmental footprint.
