D knows how much slower the head of the bullet train and G head of the head

On a case-by-case basis:

The normal operating speed of the D-shaped EMU is 200 250km h, and the normal operation speed of the G-prefix high-speed EMU is 300km h (there used to be a 350km h high-speed railway, but now the roof speed is 310 320 per hour after the speed is reduced). Generally speaking, there is no big problem that the G car is faster than the D car. In terms of average speed, the 200 bullet train is about 130 160, the 250 bullet train is about 190 200, and the 300 high-speed bullet train is about 250.

Next, there are a few "alternatives" to remove:

Existing line EMUs: EMUs running on old lines have been phased out with the opening of more and more new high-speed railways. In 2007, after the sixth big speed-up, the speed of the EMU reached 200 and some 250 on the speed-up reconstruction section, but then it was fully reduced to 160, which is almost the same as T and Z.

Some existing lines renovated in the name of "intercity", such as Jinshan intercity and Shenfu intercity, are even slower to more than 100 kilometers per hour - fortunately, the whole process of intercity railway is relatively short;

Pseudo "high-speed rail: some railway lines design standards are not high enough (generally the early start of the 200 250km h passenger and freight line, the current operating speed is generally 200 kilometers), although after the opening of the G high-speed train, but limited by the line foundation is really "high-speed" can not up. The speed of this type of G car is no different from that of D car on the same line, so it is ridiculed as "pseudo-high".

Fortunately, the fare is also the same as the D car, and it is still a penny for every penny. As for why the G prefix is arranged, because these high-speed bullet trains can still reach 300km h after entering the high-standard passenger dedicated line, but they can't run up on the 200&250 line. Typical:

Qinshen Passenger Dedicated, Shitai Passenger Dedicated, Jiaoji Passenger Dedicated, Shanghai-Hanrong Railway, Southeast Coastal Passenger Dedicated Line, Hengliu-Liunan Line.

The fastest D-prefix: The Beijing-Guangzhou high-speed railway and the Beijing-Shanghai high-speed railway are one of the few pairs of D-shaped trains, because they actually use the bottom of the G-prefix high-speed bullet train, and the speed can reach the same as the G-prefix of more than 300km h, and the fare is still according to the D-prefix - very good value for money, right? It's just that it's hard to find.

At present, it can be found, Beijing West - Wuhan D2031 2, Wuhan - Guangzhou South D2101 2, Beijing South - Jinan West D401 2, D403, etc. (the same is true for the former Beijing South-Qingdao D car, but now it is gone);

The slowest G prefix: Regardless of special circumstances, the slowest G car currently running is probably the Beijing West-Chengdu East and Beijing West-Chongqing North G cars added to the Spring Festival this year - the 160km h design standard of the Yiwan Railway makes the Jingrong and Beijing-Chongqing G also have a speed limit of 160 on this section; Of course, the same is true for the Yiwan line D car.

All I can tell you is a lot slower.

The average speed is faster than the g, but it also depends on the number of stations.

High-speed railway EMUs (G prefix), intercity EMU trains (C prefix), EMU trains (D prefix), direct express passenger trains (Z prefix), express passenger trains (T prefix), fast passenger trains (K prefix), inter-bureau ordinary passenger express (1001-2998), tube ordinary passenger express (4001-5998), temporary passenger trains (L prefix), temporary tourist trains (Y prefix), ordinary passenger slow trains (6001-7598), commuter trains ( 7601-8998).Note: The original tube express train (with an N prefix) has been cancelled on 2009-04-01.

For details, please refer to the numbering rules of Chinese railways.

High-speed railway EMU (G prefix).

Since December 26, the Wuhan-Guangzhou high-speed railway has run 23 trains, according to the regulations, the number of high-speed EMUs on the Wuhan-Guangzhou high-speed railway has a new letter prefix, which is "G", which means "high-speed".The No. 1 car G1001 at the beginning of the G word is the direct train from Wuhan to Guangzhou South Railway Station.

The number of trains is also "exquisite": the mantissa of the train departing from Wuhan is a single number, and the mantissa of the return train from Guangzhou South Railway Station and Changsha South Station is a double number. The direct train number of Wuhan-Guangzhou South Railway Station is G1001 and G1003......; There are stops on the way, and the trains are G1021, G1023 ......g1057 times; Shanghai (Hongqiao) - Nanjing: G7001 G7162; Shanghai (Hongqiao) - Hangzhou train number is G7301 G7449; Wuhan-Changsha South train number is G1101, G1103 ......

Intercity EMU trains (with C prefix).

On August 1, 2008, the Beijing-Tianjin intercity railway was officially put into operation to the public, and the newly opened train number is C+4 digits, which means intercity trains, with a maximum speed of 350 kilometers per hour. The standard pronunciation of the railway system is "city x times".The range of trains between Beijing and Tianjin is C2001 and C2282.

EMU trains (prefix D).

The maximum speed is 250 km/h. CRH1A, CRH1B, CRH2A, CRH2B, and CRH5A are the main types. Among them, the Guangzhou-Shenzhen line uses this car for the whole line.

According to the number of trains, D1-D4000 is an inter-bureau train, and D4501-D7300 is an intra-tube train. D4501 D4580 times in Beijing Bureau, D5001 D5050 times in Shenyang Bureau, D5051 D5100 times in Xi'an Bureau, D5401 D5700 times in Shanghai Bureau Shanghai-Kunming Line, D6001 D6200 times in Jinan Bureau, D6200 D6400 times in Nanchang Bureau, D7001 D7300 times in Guangzhou Railway Group. The standard pronunciation of the railway system is "bullet train x times".
