Background

In 1876, the first rail appeared in the land of china, which was the wurime rail constructed in chinese by joy and ocean of the united kingdom. By means of a plurality of design drawings of England engineers, mine workers adopt old materials such as channel iron of a hoisting boiler and a vertical derrick at that time to trial-manufacture a 0-3-0 train. Five years later, under the supervision of the ministry of government and foreign affairs, the railway from Tangshan to xu each village was built in 1881, thereby uncovering the sequential curtain of autonomous railway building in China. By the end of Qingchao, the Chinese railway operating mileage reaches 9000 kilometers. By the beginning of the establishment of new China in 1949, the mileage of China railway reaches 2.18 kilometers. China railway is only 7.3 kilometers by the end of 2003, and the number of the railways is only 5 kilometers in more than 50 years, so that people are less than one cigarette. By the end of 2014, the national railway service mileage reaches 11.2 kilometers, the high-speed rail service mileage reaches 1.6 kilometers, and the western region service mileage reaches 4.4 kilometers. In recent years, China railway and rail transit have attracted more attentive achievements, and particularly, high-speed railways, motor trains and the like are developed rapidly, and the motor trains generally refer to rail vehicles which bear operation loads and are provided with power; however, in modern motor train units with concentrated power, the motor trains more closely resemble the roles of the locomotives in a conventional train, and such motor trains generally do not carry operational loads. In china, the speed per hour is as high as 200 or more, and the use of CRH and harmonious trains is called "motor train unit". The train of the motor train unit in China is divided into three major levels, namely a high-speed motor train unit (the speed per hour is 250 or more, the label G mainly corresponds to a high-speed railway), and the upper limit speed per hour is not available; the general motor train units or the medium-speed (labeled D, the speed per hour is 160 and 200 kilometers, mainly corresponding to fast railways) and low-speed motor train units (the Nanche Qingdao company extends the technical capability and studies the speed per hour to be 140 kilometers so as to adapt to urban light rails).
