Physics ISP Summary Introduction When English inventor Richard Trevithick introduced the steam locomotive on 21 February 1804 in Wales, it achieved a speed of 8 km/h (5 mph). In 1815, Englishman George Stephenson built the world's first workable steam locomotive, commissioned by the Killingworth colliery. In 1825, he introduced the first passenger train, which steamed along at 25 km/h (16 mph).

Although there have been derailments, in the almost two decades of daily operation, there has been no casualties. At high speed, it is impossible to read line-side signals. All signaling information is transmitted to the train through the rails directly to onboard monitors in the cab. Most of the high-speed train functions are controlled digitally, true to being the vehicle of the digital age.
