Train, human traffic tools. In 1804, by the British mining engineer de Rivet Silk used Watt's steam engine, built the world's first steam locomotive, speed of 5 km to 6 km.

Train
In early 1804, a man named de Rivet Silk British mining engineer, first by Watt's steam engine built the world's first steam locomotive. This is a single cylinder steam engine, pulling 5 carriages, its speed is 5 km to 6 km. This is not the design of locomotive cab, motorcycle driving, drivers with driving in the car while walking. Because at that time the use of coal or firewood, so people call it "the train", and has been in use ever since. Train
Mechanical most important traffic tool in human history, known as early steam locomotive, also called train. Independent track. According to the load of railway train, bus can be divided into cargo trucks and passenger; also have both van. In 1781, train pioneer George. Stephenson was born in a British family of miners.Until the age of 18, he is still a not know a single word of illiteracy. He ignored theothers, and seven or eight year old children sitting in the classroom to learn together. In 1810, he began manufacturing steam locomotive. In 1817, when Stephenson decided he presided over the construction of the railway line from Liverpool to Manchester to assume full use of steam transport task. However,skeptical conservative owner of the railway has the capacity of steam. They put forward, fixed edge of the railway traction machine, the traction rope to train.Stephenson in order to let people fully believe that the performance of the train,to create a good performance of the "rocket" train. The excellence of this locomotive doubters finally changed his attitude, Liverpool - Manchester railwayhas therefore become the world's first completely by the steam engine transportrailway line. The earliest use of coal-fired steam power coal-fired steamlocomotive is a big disadvantage is must add coal, water is arranged in therailway facilities, but also in the operation of a great deal of time to add coal and water for the locomotive. These are not economic. At the end of the nineteenth Century, the study of power and coal-fired steam locomotive many scientists to.One, the train; the world's first true orbit running on steam train is designed by the Cornish Engineer Charlie Trevithick. It trains have four power wheels, run in February 22, 1840, when empty, the speed of 20 kilometers per hour, load, 8kilometers per hour (the equivalent of one brisk walking speed). Unfortunately,overwhelmed by the weight of the train tracks. Two, electric locomotive; in 1879,Germany's SIEMENS electric company developed the first electric locomotive,weighing about 954 kg, only did a performance at a Berlin trade exhibition. In October 27, 1903, SIEMENS and Ge Corp developed the first practical electric locomotive is put into use. The speed of 200 kilometres per hour. Three,motorcycle fuel; in 14, Germany successfully developed the first gasolineinternal combustion engine. And its application in railway transportation, ushered in a new era of internal combustion locomotive. But this locomotive burninggasoline, cost is too high, is not easy to popularize. In 1924, Germany and the United States, France and other countries in the successful development of thediesel locomotive, and widely used in the world. In 1941, the Swiss developed fuelsteam locomotive model, for diesel fuel. With the advantages of simple structure,small vibration, good operation performance, therefore, widely used in instrial countries. Twentieth Century since 60 time, countries are vigorously develophigh-speed trains, for example the French Paris to Lyon high-speed train speedreached 260 km; high speed train in Japan from Tokyo to Osaka when it has reached 200 km. People still don't meet the high-speed train such. France, Japan and other countries take the lead in the development of Maglev train. China has also built the world's first commercial maglev line in Shanghai by subway Longyang Road station to Pudong airport. This train is suspended in orbit, speed of 400-500 km.
