What does the revival sign at the beginning of D mean?

In the hot summer, many friends will choose to take the high-speed train when they take their children out to travel. When waiting for the bus in the waiting room, some children will ask out of curiosity: Why do some trains start with G and some with D? Which is revival? Which is "harmony"? Today Sawtooth tells you the meaning of the name of the high-speed train we took.

20 17 12.27, Xi 'an EMU, the train is ready to go.

G and D played the magnificent music of China.

G comes from the first letter of high-level words, and D comes from the first letter of verb words. Knowing this source, let's talk about the three categories of high-speed railways in China:

1. Design high-speed railways with a speed of 300-350km/h, such as Beijing-Shanghai high-speed railway, Beijing-Guangzhou high-speed railway, Shanghai-Kunming high-speed railway, Beijing-Tianjin high-speed railway and Guangzhou-Shenzhen-Hong Kong high-speed railway. 2. Design high-speed railways with a speed of 200-250km/h, such as Qinhuangdao-Shenyang passenger dedicated line (now Qinhuangdao-Shenyang section of Beijing-Harbin line), Guangzhou-Shenzhen line, Hangzhou double-track line and other lines. 3. Railways with a design speed of 200-250 km/h run on the same line as buses and trucks, such as Hanyi Railway and Liu Heng Railway. As can be seen from the division, the trains starting with G run in 1 category, and the trains starting with D run in categories 2 and 3, which can be simplified as that the trains starting with G run above 250km/h and the trains starting with D run below 250km/h..

201April 9, 9. The train runs in Suzhou section of Beijing-Shanghai high-speed railway.

What needs to be explained is the difference between high-speed rail and bullet train. High-speed rail refers to the high-speed line in the railway network, and the bullet train refers to the vehicle equipment running on the high-speed line. Because high-speed rail is a concept of vehicle-line coordination in folk discourse, G and D trains are confused.

Past life, the history of CRH EMU.

"Harmony" was put into operation on April, 2007 18 after the sixth speed increase of China Railway. This name represents the principle of "harmony between man and nature" in Scientific Outlook on Development, and realizes the idea of "building a harmonious society" by General Secretary Hu Jintao. In addition, it also means that as a means of building a harmonious society, railway development can be coordinated with economic and social development. CRH is the abbreviation of CRH (China Railway Expressway).

Harmony was once the most technologically advanced EMU train in Chinese mainland. The basic speed is more than 200 kilometers per hour and the top speed can reach 350 kilometers per hour. At that time, the Ministry of Railways (now known as the Railway Corporation) purchased high-speed railway vehicle technology from Bombardier, Kawasaki Heavy Industries, Alstom and Siemens, and to some extent, it was produced by the vehicle manufacturing enterprises under CRRC Group (which was not merged at that time, and the locomotives were manufactured by China South Locomotive and CNR respectively), and then independently innovated and developed on this basis, which can be divided into the following four categories:

Harmony CRH 1 EMUs Harmony CRH 1 EMUs are CRH series ordered by the Railway Corporation from Qingdao Sifang Bombardier Railway Transportation Equipment Co., Ltd. (formerly known as "Qingdao Sifang-Bombardier-Bauer Railway Transportation Equipment Co., Ltd.", abbreviated as BSP), and the technology is provided by Bombardier Company of Canada (the prototype is Regina C2008 designed by Bombardier Transportation Company for Swedish National Railways)

CRH/KOOC-0/EMU mainly includes CRH/KOOC-0/A, CRH/KOOC-0/B, CRH/KOOC-0/B and CRH/KOOC-0/A-A, among which CRH/KOOC-0/B and CRH/KOOC-0. This series is designed to run at a maximum speed of 250 kilometers per hour, and runs in Guangzhou Bureau, Nanchang Bureau and Shanghai Bureau, with a small amount in Chengdu Bureau.

CRH 1A

CRH 1A and A-A are both small groups with 8 cars, which adopt 5-drive and 3-traction mode (that is, 5 powered cars and 3 unpowered cars).

CRH 1B

CRH 1B and 1E are 16, and the train is driven by 10.

The oncoming CRH 1E

As of April 20 18, there were 260 sets of CRH 1 series high-speed trains leaving the factory.

The early CRH 1A and CRH 1B models are similar to the subway in appearance and ride experience, and mainly perform intercity railway transportation tasks. This series of prototypes also mainly perform intercity railway transportation tasks. So it is called "big subway" in the eyes of train fans.

Harmony CRH2 EMU Harmony CRH2 EMU is a CRH series ordered by China Railway Corporation from Kawasaki Heavy Industries of Japan and CRRC Qingdao Sifang Locomotive & Rolling Stock Co., Ltd., and the technology is provided by Kawasaki Heavy Industries of Japan (the prototype is Kawasaki Heavy Industries Shinkansen E2- 1000 EMU), and CRRC Qingdao Sifang Locomotive & Rolling Stock Co., Ltd. is responsible for domestic production. It is the main model of the sixth speed increase.

CRH2A has good air tightness, more comfortable and soft seats than other Harmony series, and a good suspension device, which makes the train run more smoothly, thus making CRH2A a leader in China's high-speed railway EMUs, and this type of car has also become the most highly rated EMU by railway fans in terms of comfort. Since then, many kinds have been derived. In 2007, Spring Festival travel rush craze (CRH2A model) was put into operation for the first time.

Up to October 20 14, 165438+ 10, * * 343 sets of CRH2 series emus have been delivered. With the delivery of the last CRH2A to taiyuan railway administration, it means that CRH2 series EMUs are officially discontinued.

The sub-models of CRH2 EMU mainly include: CRH2A/A, CRH2B/B, CRH2C, CRH2E, CRH2G and CRH2J. Except for CRH2C, which has a designed top speed of 350km/h, all other top speeds are 250km/h.. Speed up for the sixth time, and carry out large-scale driving on trunk railways such as Beijing-Shanghai, Wuhan-Guangzhou and Zhengxi. Train fans will call it hairtail because of its shape (CRH2A, B, E models). Of course, running fast 2C is called hairtail.

CRH2A

CRH2A/J trains with 8 cars as a group, which is in the mode of 4 moving and 4 towing.

CRH2B

CRH2B/E train 16 train sets are in large groups, with 8 moving and 8 towing modes.

The early CRH2E sleepers are horizontal, and the new CRH2E sleepers are vertical.

Among them, CRH2E refers to sleeping cars except dining cars and cars with second-class seats at both ends.

20 19, Changzhou, Jiangsu, a CRH2C train runs in Shanghai-Nanjing intercity.

CRH2C trains 8 cars in groups, 6 cars moving and sleeping, and 2 cars pulling. 2C is modified on the basis of 2A, and its speed is increased to 350km/h..

Harmony CRH3 electric emu Harmony CRH3 electric emu is a CRH series ordered by China Railway Corporation from Siemens Transport Group of Germany and CRRC Tangshan Rail Bus Co., Ltd., which adopts the technology provided by Siemens Company of Germany (prototype is Siemens ICE3) and CRRC Tangshan Rail Bus Co., Ltd. is responsible for domestic production (CRH3A only). CRH3C is produced by Tangshan Railway Passenger Car Co., Ltd. and Changchun Railway Passenger Car Co., Ltd. respectively.

Harmony CRH3 EMU mainly includes CRH3A (250km/h), CRH3C (350km/h) and CRH3F (160km/h). By 2065438+March 2008, * * 139 CRH3 train will leave the factory. "Rabbit" is the nickname of CRH3C for train fans.

CRH3A

The CRH3A/C is grouped into 8 carriages, with 4 moving modes and 4 traction modes.

The front of the car looks like a rabbit's CRH3C.

CRH3F adopts 2 moving, 2 dragging and 4 grouping, which can be extended to 6 grouping or 8 grouping. It has the upgrade ability of 200 kilometers per hour and the reconnection function.

Harmony CRH5 EMUs Harmony CRH5 EMUs are CRH series ordered by China Railway Corporation from Alstom and CRRC Changchun Railway Passenger Car Co., Ltd. in China (because the number 4 is avoided, 5 is used as the product code of this series). Alstom France provides technology (manufacturing basic prototype for Alstom Pendolino EMU), and CRRC Changchun Railway Passenger Car Co., Ltd. is responsible for domestic production.

Eurostar and France Railway's famous TGV are all produced by Alstom, which is different from the centralized power supply design of TGV. CRH5 is based on Pendolino wide-body tilting train in Alstom, France, but the tilting function is cancelled. The car body is based on ETR600/6 10 EMU of Italian Railway.

The Harmony CRH5 EMU mainly includes CRH5A, CRH5G, CRH5J and CRH5E, and the output of 5J and 5E is slightly less. The maximum design speed is 250km/h, and the most we see is 5A.

At present, CRH5 is the only EMU that can stop at a low platform and adapt to the low temperature in Northeast China. Therefore, CRH5A is favored by Harbin Railway Bureau and Shenyang Railway Bureau. From July 2004 1, 2065438, according to the new specification, the alpine type was officially named CRH5G, and the sandstorm prevention type was officially named CRH5H.

As of September 20 17, 227 CRH5 series trains have been delivered, one of which is No.0 high-speed comprehensive inspection train.

Shendan Passenger Dedicated Line Station stops at CRH5A platform.

CRH5A/G are all small groups of 8 cars in the whole train, and adopt the mode of 5 moving and 3 towing.

CRH5H stops at Xi 'an North Station (sandstorm prevention type)

2065438+On July 6th, 2007, CRH5G technology was upgraded to Xi Anbei EMU of Xi Railway Bureau, which will be used as a high-speed train added by Xi Bureau after the opening of Baolan high-speed railway. According to the characteristics of Lanzhou-Xinjiang Railway, this type of EMU can run normally under the severe cold condition of MINUS 40℃ through improvement, and has the ability to resist severe weather such as sandstorm, rain, snow, fog and ultraviolet rays.

These are the main EMU models of various high-speed railways at present. First, introduce the high-speed EMUs with a speed of more than 350 kilometers per hour.

Carry forward the past into the future, CRH380 series was born.

CRH380 series was introduced from four advanced companies in the world, and was born after being digested and absorbed by major domestic railway equipment manufacturers. The original intention of this series is to design high-speed EMUs with a speed of more than 350 kilometers per hour, which mainly includes the following four types:

1.CRH380A(CRH2-380) is a new generation of high-speed EMUs produced by Qingdao Sifang Locomotive and Rolling Stock Co., Ltd. of CRRC Group on the basis of CRH2 series. 2.CRH380B(CRH3-380) is a new generation of high-speed EMUs developed on the basis of CRH3 series, which is jointly produced by CRRC Tangshan Rail Bus Co., Ltd. and CRRC Changchun Rail Bus Co., Ltd.. CRH380C(CRH3-380) is a new generation of high-speed EMU produced by CRRC Changchun Railway Passenger Car Co., Ltd. on the basis of CRH3 series. 4.CRH380D(CRH 1-380), a new generation of high-speed EMUs produced by Qingdao Sifang Bombardier Rail Transit Equipment Co., Ltd. (BST) based on Bombardier ZEFIRO380 ultra-high-speed EMUs. Introduction of CRH380A Series 2065438+On July 26th, 2008, CRH380A Series will be launched in Beijing West Railway Station.

20 10 On September 28th, CRH380A high-speed EMU conducted high-speed test on Shanghai-Hangzhou Passenger Dedicated Line. At 10: 40 in the morning, the trial run speed of CRH380A train (train number G5500 1) from Shanghai Hongqiao to Hangzhou reached 4 13.7 km. Less than an hour later, 1 1: 37, on the way back to Shanghai Hongqiao for trial operation (train number G55002), the top speed reached 4 16.6 kilometers per hour. This high-speed test has twice refreshed "the first speed of China Railway" and at the same time refreshed the world's "the highest test speed of normally operated grouped trains" (the highest test speed of specially modified trains is France).

On February 3, 20 10, 10, CRH380AL EMU carried out high-speed test in Beijing-Shanghai high-speed railway. Before the train started the high-speed test, the launching ceremony of the new generation high-speed train Harmony CRH380A was held at Xuzhou East Station at 10: 35 that morning. 165438+ 0: 06 am, the train leaves from Zaozhuang station. 1 1: 28, the train speed near Suzhou East Station reaches the maximum running speed of 486.1km; 1 1: 39 arrived at Bengbu south station. The train took 34 minutes to run 220 kilometers, with an average speed of 388 kilometers per hour. Following the trial operation of CRH380A on Shanghai-Hangzhou Passenger Dedicated Line on September 28th, which set a speed of 4 16.6km/h, China High-speed Railway once again refreshed the "Maximum Test Speed of Marshalling Trains in Normal Operation"; Japan's Ministry of Land, Infrastructure, Transport and Tourism said that CRH380A EMU has successfully surpassed the Japanese speed record of 443 kilometers per hour set by 300X EMU at 1996.

CRH380A series is an electric emu driven by decentralized power and alternating current. A adopts 6-drive 2-trailer 8-car small group (AL adopts 14-car 2-trailer large group), and the car body is aluminum alloy hollow profile car body. In order to cope with the passenger flow between Nanjing and Shanghai during the Golden Week of November, Shanghai Railway Bureau arranged CRH380A to open its first passenger service on September 30th at 20 10, June 10 and June 10. 201010/On October 26th, CRH380A was officially put into operation on the Shanghai-Hangzhou Passenger Dedicated Line. CRH380AL was officially put into operation in Beijing-Shanghai high-speed railway on May 30th, 20 1 1.

By 2065438+2007 10, a total of 448 CRH380A series EMUs were delivered. Its slender front is also nicknamed "mouse" by fans.

CRH380AL is parked in the garage.

Introduction of CRH380B Series Technically, CRH380B EMU is a new generation of high-speed EMU developed on the basis of CRH3C. Compared with CRH3C, the continuous running speed is increased from 300 km to 350 km, the maximum design speed is increased from 350 km to 380 km, and the maximum test speed is over 400 km. Performance optimization is mainly to improve traction power, reduce transmission ratio and drag reduction of EMU aerodynamic shape, while train comfort optimization is mainly to improve train damping performance and drag reduction. .

20 16 12.23, Changzhou, Jiangsu, CRH380B stops at the Shanghai-Nanjing intercity line.

CRH380B also adopts the full train formation mode of 8 cars, 4 moving and 4 towing; CRH380BL adopts 16 train, with 8 moving and 8 towing. In addition, there are CRH380BG EMU trains, all produced by Changchun Railway Passenger Cars, which adopt the mode of 8 cars, 4 moving and 4 towing. This type of car is cold, mainly provided for Harbin-Dalian passenger dedicated line.

By July of 20 17, 66 1 CRH380B series emus had been delivered.

Brief introduction of CRH380C series Beijing-Shanghai high-speed railway is the longest and highest standard high-speed railway in the world. The development of a new generation of high-speed trains is a huge re-innovation project based on digestion and absorption, and CRH380C has been put on the project agenda. The development project was named CRH3-350 at that time. CRH380C EMU is a new generation of high-speed EMU developed on the basis of CRH3C and CRH380BL.

CRH380CL emu

CRH380C series are all 8-motor and 8-trailer 16 cars, so all models are CRH380CL. By March of 20 13, all 25 sets of CRH380CL series EMUs have left the factory.

CRH380D series CRH380D EMUs adopt the grouping mode of 8 cars, 4 cars and 4 trailers, and the number of trains can be increased to 16 through two sets of couplers. The maximum operating speed is 350 kilometers per hour, the designed maximum speed is 380 kilometers per hour, and the maximum test speed is 420 kilometers per hour.

CRH380D runs on Shanghai-Nanjing intercity.

By 2065438+August 2006, all 85 CRH380D series EMUs have been delivered.

For a long time, the revival took off.

Fuxing high-speed EMU (formerly known as China Standard EMU, renamed as its current name on June 25th, 20 17) is the general name of high-speed EMU independently developed by CRRC and operated on domestic passenger dedicated lines and high-speed railways. The maximum running speed of existing EMU models is 160, 250 and 350 km/h, which is mainly distributed power and adopts AC-driven aluminum alloy hollow profile car body. As the main model of China's high-speed railway and ordinary-speed railway, it will replace the existing china railway high-speed and eliminate the railway passenger cars currently running on ordinary-speed railway in the future.

On July 19, a Fuxing CR400BF train was ready to go.

Naming rules "Fuxing" High-speed EMU adopts the naming rules of "CR+ number+1-2 letters":

CR is the abbreviation of China Railway Corporation.

Numbers are speed grade codes, which represent the maximum speed of 200, 300 and 400 kilometers per hour respectively, and correspond to the operating speed of 160, 250 and 350 kilometers respectively.

The first let after that numb is the manufacturer's technical platform code,
