Mercedes-Benz’s Harmony train
When it comes to trains, everyone is familiar with them. It refers to vehicles running on railway tracks, usually consisting of a number of powered vehicles (motor vehicles) and non-powered vehicles (trailers). One of the modern important means of transportation for travel.
Early traditional trains consisted of one to three locomotives pulling several carriages or wagons. Modern new trains have appeared with multiple carriages with self-powered EMUs, trains and maglev trains.
Types of train trips
Different countries have different types of train trips. In the my country's national railway transportation system, there are two types of trains: normal speed trains and EMUs.
EMU train, is a type of high-speed passenger train. In the ticketing system, the beginning of the train number is prefixed with a capital letter "D" (taken from the initial letter of the Chinese pinyin of the Chinese character "moving"), referred to as "D prefix train " , it was officially used in 2007 after the sixth major speed increase of my country's railway .
- High-speed EMU train , which is a high-speed EMU train differentiated from EMU trains (from December 26, 2009). In the ticketing system, the beginning of the train number is prefixed with the capital letter "G" (taken from the Chinese character "高", the first letter of the Chinese pinyin), referred to as "G" trains (people used to call high-speed rail), dedicated to trains operating at a speed of more than 300 kilometers per hour.

- Ordinary EMU trains, after the high-speed EMU trains, the original EMU trains (trains with the prefix D) are changed to "(ordinary) EMU trains ", with a maximum operating speed of 160~250 Km/h, as a low-level passenger EMU passenger train, it mainly undertakes medium and long-distance passenger transport tasks, and some intercity EMU trains (referred to as "C prefix trains" in 2008) to and from short-distance inter-city from 1st).
The difference between high-speed rail and bullet train
From the types of train trips, we can easily know that what people call high-speed rail (G) and bullet train (D) in our country, strictly speaking, they belong to bullet trains, and the former (G ) is called a high-speed EMU train, and the latter (D) is called an ordinary EMU train.当然，如果仔细考究一下，它们两者还有如下几点具体区别：

- 速度不同
G字头高速动车组列车：运行时速300-350千米/小时
D字头普通动车组列车：运行时速200-250千米/小时
- 车型不同
D字头通常使用：CRH1、CRH2（除2C）、CRH5系列动车组等
G字头通常使用：CRH2C、CRH3、CRH380、CR400AF/BF Etc.
- compartment seats are different
G prefix train : business seat, first class seat, second class seat
DPrefix train : first-class seat, second-class seat
- different rails
G prefix train: The rails used are special rails, which is one of the reasons why it is called high-speed rail.
D-prefixed trains: The rails used can be either special rails for high-speed rail or modified ordinary rails, which are compatible.

- has different driving requirements
G-prefixed trains: can be called a special line, so there are few platforms set up on the whole line.
D prefix train: There are more platforms on the whole line, such as the intercity train (C) running on the intercity line.
my country is a big country with high-speed railways. Currently, the operating mileage of high-speed railways ranks first in the world (covering four speed grades of 200, 250, 300 and 350). On October 21, 2020, the key project of "Advanced Rail Transit" - 400 km/h cross-border interconnected high-speed EMU rolled off the production line at CRRC Changchun Rail Bus Co., Ltd. . The designed operating speed of the train is 400 km/h, and it can run between international railways with different climate conditions, different gauges, and different power supply standards. It has the characteristics of energy saving, environmental protection, active safety, and intelligent maintenance.
It can be expected that my country's high-speed rail technology will have greater development in the future, let us look forward to it together!
