Railways were the first form of rapid land transportation and had an effective monopoly on passenger traffic until the development of the motor car and airliners in the early-mid 20th century. Speed had always been an important factor for railroads and they constantly tried to achieve higher speeds and decrease journey times. Rail transportation in the late 19th Century was not much slower than non-high-speed trains today and many railroads regularly operated relatively fast express trains which averaged speeds of around 100 km/h (62 mph).
High-speed rail development began in Germany in 1899 when the Prussian state railway joined with ten electrical and engineering firms and electrified 72 kilometres (45 mi) of military owned railway between Marienfelde and Zossen. The line used three-phase current at 10 kilovolts and 45 Hz.
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. While there is no single standard that applies worldwide, new lines in excess of 250 km/h and existing lines in excess of 200 km/h are widely considered to be high-speed.
