Steam train is the earliest train type, which first appeared in1at the beginning of the 9th century. British engineer george stephenson designed the first commercial steam train "Brayton" in 18 14, and built the world's first passenger railways-Stockton and Darlington railways in 1825. This marks the beginning of the steam train era.
At the end of 19, with the progress of power technology, electric trains began to appear. 188 1 year, the French designer Gustave Galal made the first electric train. Since then, countries have introduced different forms of electric trains, such as DC trains and AC trains. The appearance of electric trains makes trains more efficient and environmentally friendly.
From the middle to the end of the 20th century, the development of high-speed trains has made a major breakthrough. 1964, Japan launched the world's first commercial high-speed train "Shinkansen", running at a speed of 2 10 km per hour. Since then, high-speed trains have been developed around the world, and the train speed record has been constantly refreshed. At present, China's high-speed railway network is one of the most developed and huge high-speed train systems in the world.
Maglev train is a kind of train based on magnetic principle. Magnetic levitation technology can make the train off the track and run quickly in suspension, reducing friction and air resistance, thus achieving higher speed. Germany developed the first experimental maglev train in 197 1 year. At present, maglev trains have started commercial operation in some countries and regions.
With the development of science and technology, automation technology is more and more widely used in trains. With the development of automatic driving technology and signal control technology, the train can realize a higher degree of intelligent operation. For example, some countries have begun to use subway trains with autonomous driving technology.
The influence of trains on human beings.
1. Transportation: As a fast and efficient means of transportation, the train has greatly changed people's travel mode and material transportation. The appearance of trains makes it easier for people to cross countries and regions, and promotes trade, tourism and personnel flow. During the industrial revolution, the construction of train and railway network enabled industrial products to be transported quickly and cheaply from the place of production to the market, which promoted the process of industrialization.
2. Economic development: The development of trains has greatly promoted the economy. Trains have large transport capacity and high speed, which can quickly connect different regions and expand the market. The construction of railways has promoted the prosperity of engineering and construction, and stimulated the development of iron ore, steel and coal industries. At the same time, trains have become an important transportation hub in many cities, which has promoted the development and prosperity of cities.
3. Technological progress: The development of trains needs the support and innovation of various technologies, which has promoted technological progress in related fields. These include the innovation of steam engine, power transmission, signal control and track technology, and the development of these technologies can also be used for reference in other industries and fields.
