The locomotive adopts the "bullet" shape. "High-speed rail locomotives (ie, locomotives) will adopt a streamlined 'bullet' shape." Huang Qiang said that the air resistance will increase significantly after the train speed exceeds 160 kilometers per hour. Therefore, the locomotives of the Beijing-Shanghai high-speed rail will adopt a "bullet" shape that can reduce the resistance. This shape is not only beautiful and smooth, but also effectively reduces the "micro-pressure wave" when the train "rushes into" the tunnel. Huang Qiang made an analogy. "If you pull out the cork suddenly, there will be a "squeaky" sound. When the train enters the tunnel, it will suddenly compress the gas in the tunnel, and it will also produce strong air waves and whistling sounds. "The model will greatly reduce this resistance and noise.
The windshield is undergoing development and anti-collision test. "We are already developing the locomotive windshield and anti-collision test." Huang Qiang said that because the high-speed train is more likely to encounter near-ground objects such as birds, gravel, rain and fog than airplanes. The "attack", so the anti-collision and see-through performance of the windshield of the high-speed rail locomotive, will also resemble the glass of the aircraft cockpit. Experts have been conducting targeted tests, such as releasing steel bullets from a certain height and dropping the impact glass to "test" the strength and toughness of the glass. Huang Qiang said that in the future, the windshield of the high-speed railway locomotive will be composed of a variety of composite materials, and it will be multi-layered. It also has long-term resistance to impact and erosion of rain and fog, and it is also conducive to cleaning.

Full line of closed "coated" aluminum alloy
Huang Qiang said that the trains on the Beijing-Shanghai high-speed train will be sealed in the same way as the trains in Tibet, and they will be "wearing" aluminum alloy outerwear. First, because the weight of aluminum alloy is much lower than that of steel, it is beneficial to high-speed trains to reduce weight and speed; in addition, aluminum alloy can provide good air tightness, in the process of high-speed operation, the train surface will generate negative pressure, and two trains When you “pass byâ€, it will become positive pressure. The momentary change of positive and negative pressure requires good sealing of the car body, and aluminum alloy can do this better. “The body must be made of a single piece of aluminum alloy with the same length as the body. If it is spliced, the strength will not be enough.â€

Will inevitably have an impact on civil aviation
Will the Beijing-Shanghai high-speed railway transfer a large number of passengers from "the sky" to the "ground"? Wang Ming, deputy director of the Comprehensive Transportation Research Institute of the National Development and Reform Commission, believes that the high-speed rail will inevitably have a certain impact on civil aviation, but in the long run, the two modes of transportation are still difficult to predict. He said that although it only takes 2 hours to fly from Shanghai to Shanghai, the traffic time between the two airports is about 2~3 hours. Once the Beijing-Shanghai high-speed railway is built, the time spent on the journey is superior to the railway. It will no longer be obvious; no accident, the high-speed rail fare will be relatively low, and the impact of civil aviation is inevitable. However, he also believes that both Beijing and Shanghai are planning to build rail transit to the airport, and the ground transportation time for the flight will be greatly shortened. Therefore, it is possible for aviation to regain the advantage of “peer-to-peer†transportation between Beijing and Shanghai. However, on the Beijing-Shanghai line, in the passenger transportation market between Shanghai, Nanjing, Shanghai, Xuzhou, Shanghai and Jinan, the high-speed rail will Shows a high price/performance ratio.
Wang Ming said that after the completion of the Beijing-Shanghai high-speed railway, the passenger capacity between Beijing and Shanghai will grow rapidly, and the overall demand will gradually increase. Therefore, in the initial stage of construction, the passenger capacity of Beijing-Shanghai transportation is likely to have surplus, which will affect other modes of transportation such as civil aviation and highways, and even lead to the reduction of ticket prices.
It’s not just “one line†to enjoy high-speed rail.
After the completion of the Beijing-Shanghai high-speed railway, passengers who enjoy "fast speed" travel will not only be passengers travelling between Beijing and Shanghai, but may even radiate to the Yangtze River Delta and the Beijing-Tianjin-Hebei Ring Economic Circle, because the Beijing-Shanghai high-speed railway also has a passenger speed of 200 kilometers per hour. The advantage of the special trains is that the passenger trains with a speed of not less than 200 kilometers per hour can run on the Beijing-Shanghai high-speed railway, so they travel from Shanghai to the Bohai Bay area, as well as Harbin, Shenyang, Baotou, Lanzhou, Xi'an, Chengdu, Urumqi and Travellers to Beijing's cities in East China can greatly shorten their travel time.
Huang Qiang, chief expert of the China Academy of Railway Sciences, said in an interview with the Morning News reporter that the Shanghai-Nanjing-Hangzhou in the Yangtze River Delta and the Beijing-Tianjin-Hebei region in the Bohai Bay are expected to build passenger lines with a speed of more than 200 kilometers per hour, and to Xi'an and Harbin. The city is also expected to build a similar passenger line. In this way, trains with a speed of 200 kilometers per hour have the hope of “borrowing†the Beijing-Shanghai high-speed rail to shorten the journey time.
The old Beijing-Shanghai line was changed to the main line of freight
The existing Beijing-Shanghai Railway is only 2% of the national railway operation line, but it connects the two economic circles of Beijing-Tianjin-Hebei and the Yangtze River Delta, and bears 10.2% of the country's railway passenger traffic and 7.2% of the cargo turnover. The transport density is four times the national average railway level. Because it has been in an overloaded state, it has seriously restricted the economic development along the line. The Ministry of Railways released it to the outside world. Once the Beijing-Shanghai high-speed railway is completed, it will divert passenger and cargo from the existing Beijing-Shanghai railway: the new high-speed railway will become a passenger dedicated line, and the “old†Beijing-Shanghai railway will serve as the main line of freight. By then, the Beijing-Shanghai high-speed train will only run for 5 hours, which is about 9 hours shorter than the current express train between Beijing and Shanghai. The annual passenger transport can reach more than 80 million passengers in a single direction. It is a fast and powerful passenger transport channel. At the same time, the existing Beijing-Shanghai Railway's cargo capacity will be greatly increased, and its one-way annual cargo capacity will reach more than 130 million tons, thus becoming a large-capacity freight channel. The Beijing-Shanghai high-speed railway will meet the demand for passenger and cargo transportation in Beijing and Shanghai, fundamentally solve the situation of tight transportation capacity of the Beijing-Shanghai channel, and drive the rapid development of the economy along the line.
High-speed rail is expected to recover costs in 8 years
The Beijing-Shanghai high-speed railway runs through the three municipalities directly under the Central Government of Beijing, Tianjin and Shanghai, and the four provinces of Hebei, Shandong, Anhui and Jiangsu. It connects the two economic zones of the Bohai Sea and the Yangtze River Delta, and is also the gateway to the Northeast and North China to East China. According to the predictions of relevant departments, after the completion of the Beijing-Shanghai high-speed railway, the economic income will grow steadily, and it is expected to recover the cost after 8 years of operation.
Professor Sun Zhang of the Institute of Railway and Urban Rail Transit of Tongji University believes that the completion of the Beijing-Shanghai high-speed railway has effectively realized the “time-for-spaceâ€, reducing the cost of passenger travel and creating great value. "This will greatly promote the economic development of Shanghai and surrounding areas, and effectively enlarge the Yangtze River Delta economic circle. In Japan, the Shinkansen is called the backbone of the economic take-off, and the significance of the Beijing-Shanghai high-speed rail to the area along the line. The same is true.
