Traveling through the sword to engage in military industry.

South of Yandu.

A special railway called the Yan'an Line, which was built not long ago, looks a little different today.

All the crossings leading to this railway, which is 55 kilometers long, are now guarded by special guard forces, who will stop all vehicles that need to pass through the railway.

"Today, the Yan'an Railway needs to conduct a special test. From 9am to 11am, all railway crossings along the line will be closed to traffic!"

A simple notice was posted on both sides of the crossing, and the guards were standing guard seriously, forcing the drivers, who were originally a little confused, to calm down and wait.

As members of the University of Tokyo, they all knew very well that the relevant parties would never do anything without a purpose and deliberately delay everyone's affairs.

Today they may be able to witness another achievement of Todai.

They guessed right this time.

Today is the first test of the first generation of high-speed rail Eastern Star TGV I train and railway jointly developed by Eastern Star International High-speed Rail Company!
Professor Liu Xiaoming, chief engineer of Dongda University, is currently stationed at Yandu South Station, conducting the final inspection of the Eastern Star TGV as it prepares to depart.

This is a bullet-shaped traction electric locomotive. The prototype comes from the main world, but the electric drive technology mainly comes from Alstom's mature electric airport 6G. Behind the traction locomotive are 8 sets of passenger carriages. Each carriage has a rated seat capacity of 100, so this passenger train can carry 800 passengers when fully loaded.

Of course, there is no one in the train car today, and the simulated traction load is consistent only based on the average 70 kg weight per person.

Before the formal driving test, the engineers made careful preparations.

A large number of engineers carried out comprehensive inspections and adjustments to the tracks, vehicles, signal systems, etc. to ensure the safety and accuracy of the tests.

The test site was chosen to be the specially built Yan'an Line test track, which is an ideal place for high-speed train testing. It is far away from busy commercial lines, ensuring that the test process will not affect daily operations.

On the day of the test, the test team arrived at the test site at dawn and conducted a final inspection of the train to confirm that all systems were functioning normally.

After receiving all the test results, Professor Liu Xiaoming said everything was normal.

"Dr. Pierre, Dr. Hoffman, our tests are all normal and we are ready to start testing. Are your testing teams ready?" Professor Liu Xiaoming said to the heads of the two cooperative teams.

"No problem! Liu, we will definitely succeed." The two foreigners replied excitedly.

"Get ready! The first test of the Eastern Star TGV train begins!" With the order from Professor Liu Xiaoming, the chief commander of the test, the intercom sent the order directly to the driver's cab of the train. Ma Dongchen, the train conductor of this train test, closed his eyes, took a deep breath, and then exhaled heavily. Then he pressed the switch to start the train and it started slowly. The powerful power began to drive the train to slowly accelerate on the track.

Members of the testing team distributed inside and outside the train were each nervously monitoring various instruments and screens, recording every subtle change of the train and the tracks.

"Report to the commander-in-chief, the report from the No. 100 observation point is that the train has accelerated to kilometers, and everything is normal!" At Professor Liu Xiaoming's temporary test command center, the report information from the first observation point came through the loudspeaker.

Professor Liu Xiaoming, Dr. Pierre, and Dr. Hoffman finally smiled on their serious faces. But it was still far from celebration. In the headquarters, there was no other noise except for the reports.

Everyone is busy, constantly receiving reports from various observation points!

"Report to the commander-in-chief, the report from the second observation point is that the train has accelerated to 200 kilometers, and everything is normal!" Soon, the report from the second observation point came up.

As the speed increased, the Eastern Star TGV train began to show its true strength. The moment the information report showed that it had reached a speed of 200 kilometers per hour effortlessly, the entire test command center burst into warm applause.

"Report to the commander-in-chief, the train has stabilized at 200 kilometers per hour, and will then maintain a speed of 200 kilometers per hour as planned to reach the target station!" The train conductor of the test also issued a report, and the entire high-speed passenger train began to run at a high speed.

"Report to the commander-in-chief, the 5-kilometer section of track A is normal after the test train passed, and the road and track have not changed!" Under the test of various instruments and equipment, a large amount of data from the high-speed railway tracks was transmitted and entered into the computer for comparative analysis, and the conclusion that it was normal was quickly reached.

Soon the train passed through the 5-kilometer section B and section C, and continued until it ran through the 55-kilometer test railway line and arrived safely at the destination!

As the news that the train arrived at the destination on time, safely and stably was passed back to the command center, this time the command center cheered for a long time!

Because this time they witnessed a historic moment. The Eastern Star TGV train not only reached the target speed, but also ran smoothly at this speed, and all indicators were in line with expectations, proving the feasibility and safety of the high-speed railway technology led by the University of Tokyo.

"Professor Liu, our little TGV baby has performed amazingly. The railroad tracks were designed and built to a speed of 300 kilometers per hour. For the next return test, can we increase the speed appropriately to try out the train's maximum speed and 250 kilometers per hour long-term running test data?" Pierre became excited and prepared to skip the planned 200-kilometer test and go straight to the next speed test project.

After all, the current Eastern Star TGV train is in excellent condition. According to power theory calculations, the maximum speed of this TGV can exceed 300 kilometers per hour!

"Are we taking a step too far by doing this?" Professor Liu Xiaoming asked hesitantly.

"Professor Liu, from the perspective of our test plan, this is indeed ahead of schedule. However, considering the current status of our trains, I don't think there is much risk in testing it a little earlier. After all, there is no abnormality in the test data of the current track and railway foundation, which proves that our original target performance designed according to 300 kilometers has a solid foundation." Dr. Hoffman added.

"I just reviewed all the track data, and the instruments now show that it is completely within the design range. This is an amazing miracle, proving that the construction standards we adopted in the early stage are very reliable. Professor Liu, your experience in railway construction is indeed unparalleled."

The current 300-kilometer standard Yan'an line uses the same standards as Ren Zhongcong's main world's high-speed rail construction. It has been verified through many years of operation and testing in the main world of Dongda, so of course there will be no problems.

However, there is no high-speed rail in this world. For Dr. Hoffman, who is mainly responsible for the construction of the railway, it is incredible that Dongda directly gave a construction standard. However, during the verification process of the early construction, Dr. Hoffman did not find any process, so he was more of a witness than a supervisor for the construction of the Yan'an Line of Dongda.

The current verification results prove that there is indeed no problem with this test line under 200 km/h conditions.

Therefore, Dr. Hoffman believes that there is no problem in increasing the test speed to run the Eastern Star TGV at its maximum speed.

"Okay, we will start the extreme speed test in advance, but the extreme speed test time should not exceed 30 seconds. In addition, we will limit the 250 km/h speed test to within 10 minutes. Now we will redeploy the test plan and test points. We need to confirm the sections where the limit is reached and the sections where the 10-minute 250 km/h test is conducted, and comprehensively monitor the conditions of related supporting facilities such as the rails and roadbeds, and railway power lines."

According to the plan, the TGV train will continue to increase its speed during the subsequent six-month test, and conduct a series of high-speed running tests. These tests not only verify the performance of the train at high speeds, but also conduct rigorous inspections of infrastructure such as tracks and signal systems.

After rigorous testing, if all the results show the stability and reliability of the entire high-speed railway system under high-speed operating conditions, then it will be possible to use the Yan'an Line as a commercial operation test line for high-speed railways and begin providing the first generation of high-speed railway services to the public.

The data and analysis from these tests will provide solid technical support for the operation of this high-speed rail test line.

After intensive adjustments, the test plan was restarted.

Due to the success of the first test, everyone is more confident about the second test now being carried out.

The train returned and started accelerating, soon soaring to 200 km/h. After a few minutes of warm-up, the conductor continued to increase the power output and began to challenge the limit!
Soon, the TGV train reached a speed of 250 km/h, and after maintaining a stable speed for 5 minutes, the train conductor began to increase the power output as instructed!
260 km/h!

280 km/h!

290 km/h!

After every report of speed improvement, the command center couldn't help but speed up their heartbeats!

After all, these are not normal and mature operating speeds, but the train is speeding.

Therefore, the increase in speed also brings about a surge in everyone's heart rate and blood pressure!

300 km/h!

When a new number was frozen on the test instrument and the train cockpit instrument, the train conductor suppressed his inner excitement and maintained the high speed without increasing the output power!

At this time, looking outside from the front of the car, it feels like you are driving at lightning speed. There is no deceleration glass yet, and the telephone poles on both sides of the road that serve as reference points flash by!
The train conductor stared at the data from various instruments on the front of the train nervously. There was nothing abnormal on the entire train. However, even though the train conductor thought that the train still had the energy to set a new record, he did not have the courage to speed up any further. After all, this was already an unprecedented high speed in the history of Dongda University. Even at this speed, it would probably take many years to truly achieve.

Because to achieve this high speed, it is not only necessary to have a powerful train traction head, but also to fully consider the external limitations of the road network and power supply grid.

In fact, it is the overall improvement of the entire railway system that is needed.

When the speed reached the maximum speed of 300 kilometers per hour, the train conductor not only nervously observed the instrument data in the car, but also kept glancing at the timer next to him!
10 seconds!
The train roared forward like a roaring bullet, penetrating the wind's obstruction. Even the pedestrians around the railway could feel the oppressive feeling of the strong wind passing by even if they were hundreds of meters away!

20 seconds!
The train is moving forward as fast as ever, indicating that the drive motor still has spare power.

30 seconds!
When the time came, the train conductor immediately reduced the output power and began to slowly reduce the speed of the train.

Then the speed dropped to 200 km/h and the train completed the rest of the journey. For such an extreme test, the train conductor was under great psychological pressure and did not dare to exceed the time limit.

The train returned to the starting point smoothly at a speed of 200 km/h. Everything showed that the test was a great success!

The success of the Eastern Star TGV train test not only demonstrated the maturity of the jointly researched high-speed railway locomotive, but also verified the progress of high-speed railway network construction technology, opening up new possibilities for the future development of high-speed railways.

It proves that all the key technologies for 200 km/h high-speed railways have been broken through. The Eastern Star TGV train has great potential in improving transportation efficiency and shortening travel time. Compared with the 80 km/h speed of long-distance trains and the current 120 km/h speed of fast railways, the new high-speed railway technology has more than doubled the transportation speed!

This test verified the new development technology route direction for the modernization of global rail transportation.

The core parts of the TGV electric locomotive come from Alstom, some motors, IGBTs and testing instruments come from Ximen, and the core locomotive control system uses the latest computer from Dongda. In addition, the bullet-shaped shape and main materials of the train are also provided by Dongda. This high-speed train, which is currently the highest level in the world, is very mature.

After the first test, a comprehensive inspection of the road network and trains revealed that there were no problems at all. The current rails and electrification facilities can withstand a speed of 200 km/h, and the locomotive even ran at a speed of 300 km/h, proving that there are no problems with aerodynamics and drive power margin.

After three months of continuous testing, the road network monitoring and automated crossing barrier equipment tests were mature, and the Yan'an Line began commercial trial operation.

On this basis, Dongda began to continue building the extension of the Yan'an Line, with the goal of connecting Yandu and Tianjin, and eventually forming the first high-speed railway from Yandu to Tianjin!
This railway will be the world's first truly 200 km/h high-speed railway in commercial operation.

In the history of high-speed railway development, this 200 km/h high-speed railway is an important milestone.

As the high-speed railway on this test line is put into operation, engineers have conducted comprehensive and long-term testing and verification of the tracks, vehicles, signal systems, etc. At the same time, they will also check and adjust the operation arrangements to meet the growing needs of intercity travel between the two places and verify the commercial value of the high-speed railway!
