How many carriages does the high-speed rail have? Revealing the secrets of China’s high-speed rail organization
In recent years, high-speed rail has been the "business card" of China's transportation, and its technology and development have always attracted much attention. Many passengers will be curious when taking the high-speed rail: How many carriages are there in the high-speed rail? What are the differences between the groupings of different models? This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of the marshalling data of high-speed rail carriages, and attach a structured comparison table.
1. Basic classification of the number of high-speed rail carriages
The number of carriages on China's high-speed rail is mainly divided into two types of formations:Short formation (8 cars)andLong group (16 cars). In addition, some models also support "re-connection" operation, that is, two short trains are connected to form 16 cars for operation. The following is a comparison of the number of carriages in mainstream high-speed rail models:
| car model | Short formation (number of carriages) | Long formation (number of carriages) | reconnection pattern |
|---|---|---|---|
| Harmony CRH380A | 8 | 16 | support |
| Fuxing CR400AF/BF | 8 | 16 | support |
| Fuxing CR400AF-G (alpine type) | 8 | 16 | support |
| Fuxing CRH6 (intercity EMU) | 4/6/8 | not applicable | Not supported |
2. Why are the number of high-speed rail carriages mostly 8 or 16?
The design of the number of high-speed rail carriages is not arbitrary, but is based on the following scientific considerations:
1.Platform length limit: The standard length of China's high-speed rail platforms is 450 meters, and the total length of the 16-car train is about 400 meters, with a safety distance reserved.
2.operational flexibility: Short marshalling is suitable for lines with small passenger flow, while long marshalling and reconnection modes can quickly respond to peak demand such as Spring Festival travel.
3.Power distribution optimization: The proportion of power cars in the 8-car group is 4 motors and 4 tows, and the 16-car group is 8 motors and 8 tows to ensure acceleration performance and energy consumption balance.
3. Recent hot searches: Car innovation of smart EMUs
According to People's Daily Online, the latest Fuxing smart EMU (CR400AF-Z/BF-Z) put into use has achieved a number of breakthroughs in carriage design:
| Innovation point | Traditional carriage | Smart EMU carriage |
|---|---|---|
| Seat charging port | 2 USBs per row | 1 USB + 1 220V socket per seat |
| Accessibility | 1 barrier-free carriage | 2 barrier-free carriages (including wheelchair parking area) |
| Car WiFi | Download rate 50Mbps | Download rate 150Mbps |
4. Top 3 carriage issues that passengers are most concerned about
According to Weibo topic statistics, there have been 1.2 million discussions related to high-speed rail carriages in the past 10 days. Popular issues include:
1.“Why does my ticket show 4 cars but it’s actually 12 cars?”——Independent numbers between front and rear trains during reconnection operation
2."What car number is the dining car in?"——The short formation is in 5 cars, the long formation is in 5 cars and 13 cars
3."Which car is quieter?"——The front and rear of the car (1/8 or 1/16 car) have less vibration
5. Future trends: Variable marshalling high-speed rail technology
The latest developed by China Railway Group"Modular Variable Grouping High Speed Rail"It has entered the experimental stage and its features include:
| model | Number of carriages | Applicable scenarios |
|---|---|---|
| business model | 4 seats (all business seats) | High-end business line |
| blend mode | Section 8-12 | Regular line |
| freight mode | 6 sections (mixed passenger and cargo) | express train |
Conclusion: From standardization to intelligence, the evolution of the number of high-speed rail carriages has witnessed the technological leap of China's railways. The next time you take a bus, you may wish to count the carriages and feel the hard-core power of this "China business card".
