Chapter 697 The sound of drums in the distance (third update, please subscribe)
December 3.
This day, on the more than 100 kilometers of test track from Kuching to Yong'an.
A white streamlined train was traveling rapidly. While the train was moving, the engineers in the carriage were constantly observing various data.
After the locomotive left the research institute and drove onto this test track, the speed continued to increase. In just ten minutes, it increased from the initial dozens of kilometers to 200 kilometers.
"It has reached 220 kilometers!"
The voice coming from the front of the carriage made Feng Qingyun's heart clench. This was the designed maximum operating speed.
Amidst people’s cheers, the train is still accelerating.
"Continue to accelerate?"
"Continue!"
A few minutes later, the speed of the high-speed power train finally exceeded 250 kilometers. The first day of testing was just a basic test run and did not involve other tests. So after completing the first test drive.
Facing his delighted colleagues, Feng Qingyun just whispered to himself.
“It’s still early, this is just the beginning.”
For example, the test of the automatic train control device is different from the braking distance of only 600 meters for ordinary trains. The moving distance is as long as 2,500 meters. Since the train needs a longer distance to come to a complete stop when running at high speed, the driver's judgment alone may not be able to avoid accidents in time. Therefore, the Railway Technology Research Institute developed an automatic train control device. In addition to assisting the driver in adjusting the vehicle speed, when the train is overspeeding, the system can forcefully decelerate to ensure driving safety. In addition, in order to more effectively manage the daily operations of the line, the institute has also developed a centralized dispatching system, which will be responsible for the construction, monitoring and management of train operations on the line at a control center located near Chang'an Station.
The braking system of the new power train unit is also newly designed, and these need to be tested one by one.
Even after these tests are completed, it still involves adjustments by the locomotive company. The new power train set not only requires design and technology, but also operations and manufacturing. After all, engineers cannot draw a running train, they have to rely on workers. Use your hands to process parts one by one, and then assemble them one by one.
Building a train with a speed of 80 kilometers per hour is completely different from building a train with a speed of 200 or even 300 kilometers per hour. They use a lot of new technologies, so the requirements for skilled workers must be very different.
Only after completing all this, will it be possible to truly enter the high-speed rail era.
But while others were cheering for the successful test run, Feng Qingyun looked outside the car. His attention was not on the rainforest outside the car window, but on this test route. In the middle of the year, the Railway Technology Research Institute conducted a number of studies, one of which was the roadbed test. From the beginning, the ballastless roadbed was selected. This technology, like the seamless track, is a mature technology originated from Germany.
This experimental high-speed rail line is from Kuching to Yong'an. The 236-kilometer line includes both rainforest sections and swamp sections. One-third of the 157-kilometer test section has been completed so far. One on the viaduct. Elevated buildings have their advantages, but they also have their own troubles.
To ensure that the viaduct meets the design requirements, engineers put a lot of thought into it.
Most of the foundations along the line are soft soil with high water content and low support strength. Once the rainy season arrives, they are soaked in water for several months. The necessary foundation for laying high-speed rail on such soil German engineers do not have mature experience with ballastless tracks. Due to the different natural environments, they have not encountered similar problems, so they can only study and explore on their own.
This route is both a test route and a future operation route. After all, there are many natural environments that cannot be tested in the research institute.
“…In order to effectively control roadbed deformation and bridge settlement in swamp areas, and meet the requirements for laying ballastless tracks under soft soil foundation and regional settlement conditions, we conducted a geological survey here for half a year, and passed The geological survey has re-planned the route. Now in this section we are passing, the swamp will turn into a large lake during the rainy season. At most half a month later, this will be a large lake of hundreds of square kilometers, so we used a viaduct..." The civil engineer's There were too many technical terms, and they were obviously too technical. Feng Qingyun could not understand what he heard, but he at least understood one thing after listening to it, that is, there would be absolutely no problem for the high-speed train they built to run on such a track.
While they were chatting, Feng Qingyun turned around and asked.
"How many kilometers is this route from Yong'an now? If it is included in the plan now, can it be connected to Yong'an next year?"
The reason why Feng Qingyun asked this is because of his I have a longer-term plan in mind.
“Connect to Yongan?”
“Yes, we are now starting to conduct test runs in all aspects. If everything goes well, it will only take about half a year to complete the preliminary tests and then conduct trial runs. Since the operation is a trial operation, can the trial operation be turned into a trial operation? ”
Walter, who was chatting with his colleagues, also heard Feng Qingyun's suggestion. He walked over and asked.
“You mean, we skip the trial run and go directly to the operation?”
“It’s not about skipping, but about reducing the time. Although the high-speed power train unit applies many new technologies , However, the technical main body is still mature. If it can pass the half-year test, then there will definitely be no problems in operation, and there will definitely be no problems in the trial operation. "
The reason why Feng Qingyun has such an idea is, Mainly due to the impact of the successful atomic bomb test, foreigners will never be able to understand the mood of the Tang people. Over the past hundred years, the Tang people have lagged far behind other countries in the world in many fields such as science and technology.
Because of this, every Tang engineer is holding back a strong feeling in their heart. They don’t believe that Tang engineers will always be second to others. They all hope to reach or even surpass the world’s advanced level in their own fields. This proves that what the European and American countries can do, the people of the Tang Dynasty can also do it.
While speaking, Feng Qingyun's eyes were shining brightly, and his firm gaze met the gazes of his colleagues.
“In this way, we will not only win the title of the world’s first power train unit, but also become the first country in the world to operate high-speed railways, which will fundamentally change the world’s tracks. Transportation, and will set off a revolution. After all, the current speed of airplanes is only more than a hundred kilometers faster than it, and air tickets are expensive and subject to weather restrictions..."
Here On one point, Feng Qingyun was very accurate. Although the aviation industry has achieved great development in the past 50 years, air tickets are still unaffordable for ordinary people.
In this case, high-speed rail, which is not much slower than airplanes, will become the best choice for many people to travel.
“Compared to airplanes, high-speed rail has lower operating costs and is not slow. Even the Pacific Railway in the United States is only more than 3,000 kilometers long. If high-speed rail is used, the operation time will be from Three or four days is shortened to a dozen hours. Such high-speed railways will definitely be welcomed by the market, but the premise is that we must become the pioneers of this market. Every day we advance, we can seize this market one day earlier. .”
While others were still looking at the domestic market, Feng Qingyun had already set his sights abroad, on the other side of the ocean - after all, there was the densest railway network in the world.
Walter stayed there for a moment. He couldn't tell whether it was Feng Qingyun's words or his demeanor that moved him so deeply that he was stunned for a moment.
At this time, what Thoreau said in his "Walden" rang in his mind: Some people's steps are different because they hear the drums in the distance.
The young man in front of me who proposed the idea of high-speed railway heard the drumbeat in the distance again...
