How are the train names of China's locomotives and high-speed trains named?

Brake generally refers to a rail vehicle that carries an operational load and is self-powered, but in modern power-concentrated trains, a brake car is closer to a locomotive in a traditional train, and in China, trains traveling at speeds of up to 250 kilometers per hour or more are referred to as "brakes". In China, trains traveling at speeds of up to 250 kilometers per hour or more are called "dynamic trains" and are given the prefix "D" in front of their names, while high-speed trains are

trains traveling at even higher speeds and are given the prefix "G" in front of their names.

China's high-speed railroad, there are usually four kinds of standards. The first is the design speed of 300-350 kilometers per hour high-speed railroad, such as Beijing-Shanghai high-speed railroad, Wuhan-Guangzhou high-speed railroad. The second is a high-speed railroad designed for 200-250 kilometers per hour, such as the Qin-Shen section of the Beijing-Harbin line. The third type is the design speed of 200-250 kilometers per hour passenger and freight mixed running railroad, such as Han-Yi Railway, the new Xianggui Railway. The fourth is the transformation of the original line speed up to 200 kilometers per hour, in August 28, 2011, before the national railroad speed reduction, the operation of the Beijing-Guangzhou line Jinghan section of the train group, Hukun line Zhegan section, can be included in this category.

In fact, both D, or G, it is in the railroad transportation to the CRH moving sets executed by the passenger train. To run at 250 kilometers per hour and higher, both D and G trainsets, must be driven on high-speed railroads.
