On December 8th, the sky was as clear as the sky was clear and cloudless. The locomotive warehouse of the Sujiatun Train Depot of Shengjing, which was deserted in the past, was extremely lively.

At the entrance of the tall concrete garage, a long red banner was hung with the words "Warm welcome to our superiors to guide our work."

Not far from the garage entrance, a long wooden temporary platform was built on the east side of the vehicle maintenance line, and several staff members were decorating the ribbon-cutting red silk.

Liang Yuan followed Liang Haiping with his eyebrows down and his eyes were pleasing to the eye. Except for his unresponsive eyes looking around, he looked like a junior who was taken out to see the world by an adult.

Liang Haiping was slightly behind Liu Changhe, and the two of them talked while walking.

"I have to thank Director Liu for his trouble this time. It turns out that the 25b-s number is awkward. The factory employees say it's awkward, or the 25s double-decker bus is simple and smooth."

Liu Changhe laughed and said, "After the merger of Northeast Locomotive Factory and Shengjing Locomotive Factory, I thought that the bottom of the car was created by our Road Bureau alone. I got a 25b number. Those who don't know the inside story think it was the result of the Shanghai Bureau."

In 1987, the Ministry of Railways had 15 railway branches under its jurisdiction, including the Beiping Road Bureau, Shengjing Road Bureau, Wusong Road Bureau, and Guangzhou Road Bureau were nicknamed by people on the road. These four major road bureaus managed the "one horizontal and two vertical" national-level railway trunk lines at that time. The assets of the Ministry of Railways 80 were all in these four major road bureaus.

The Beijing Bureau is in a transcendent position in the capital, and the boss is extremely stable and no one is shaken. The other three companies have focused their attention on the position of Lao 2. The foundation of the prosperous bureau is extremely strong. The Northeast is the area with the most dense railway network in the country. The length of the railways under its jurisdiction accounts for one-fifth of the total railway mileage of the country, and the number of front-end vehicles and employees ranks first in the Ministry. When the founding of the People's Republic of China, the Ministry of Railways divided the Changchun Road Bureau into a forceful division until the mid-1980s.

If Peking is the political capital of the Republic, Wusong is the economic capital of the Republic. Jiang, Shanghai and Zhejiang are under the jurisdiction of the Shanghai Bureau, with very developed domestic economies. Therefore, the vehicle and equipment of the Shanghai Bureau have always been the most advanced in the Ministry and the best employee treatment in the Ministry. Guangzhou Road Bureau has gained the glory of the reform and opening up, and is a rising star, with a very rapid development momentum. Although it is far behind other road bureaus, its foundation is too weak and it is still a long way from the top three situations.

Before the 1990s, more than 90 ministers of the Ministry of Railways had experience in presiding over work in Shengjing or Wusong Bureaus. It can be said that the director of Shengjing Road Bureau or Wusong Road Bureau was the only way to the Minister of Railways. The directors of these two major situations were also the most direct competitors.

There are vehicle manufacturing plants in the jurisdiction of the two bureaus. The difference is that Changchun Bus Factory is a large central enterprise and is directly under the jurisdiction of the Ministry, while Nanjing Vehicle Factory, which produces 25b-type vehicle bottoms, is an enterprise under the Shanghai Bureau.

For Liu Changhe, who is well aware of the various rules of the Ministry of Railways, even if the companies in his jurisdiction are likely to be incorporated by competitors, they will definitely not tolerate them.

"Haiping, tell me a briefing. This time, Zhao Tiemin, the chief engineer of the department, came down. He was mainly interested in the ultimate speed of the 25s car bottom. I heard that the 25s Democratic German original car bottom has a construction speed of up to 160 kilometers per hour. Is this reliable?" Liu Changhe asked.

Zhao Tiemin is a famous high-speed corps of the Ministry of Railways. After returning from the West Germany investigation in the 1970s, Zhao Tiemin has been promoting the rapidization of China's railways. After becoming the Minister of Railways in 1992, he personally led the first major speed-up of China's railways. It can be said that he is the founder of China's high-speed railways.

"Director Liu, it's really hard to say about this matter. I have discussed the issue that Director Liu mentioned with the Democratic German expert group in the factory now."

"The technical information given to our factory by Democratic Germany said that the structural speed of the double-decker bottom is 160 km/h, but Democratic Germany does not have the high-speed head traction with it. The fastest locomotive in Democratic Germany is the 243 electric locomotive just introduced by our factory, with a structural speed of 140 km/h. Therefore, the double-decker bottom can only be said to be theoretically able to operate safely at a speed of 160 km/h."

After hearing Liang Haiping's words, Liu Changhe pondered for a moment and said, "Haiping, you are very cautious, much better than some units."

Liang Yuan almost laughed when he heard Liu Changhe say this. Some units in Liu Changhe's mouth are about the Nanjing factory that produces 25b double-decker underneath. The 25b structure of the Nanjing factory is said to be 120 km/h, but the body deformed as soon as it reaches 100 km/h.

"However, judging from the ring line test of the department, the potential of the 25S model undercarriage is still very great. It is a thing that has never been done since the founding of the People's Republic of China. The Northeast Locomotive Factory has left a brilliant mark in the history of China's railway vehicles." Liu Changhe said while waved his hand vigorously.

"With such excellent products in hand, the Northeast Locomotive Factory should be bigger. Since experts from Democratic Germany say that in theory, there is no problem with the 25s model under running 160 km/h, the subsequent improved models of the 25s model under running 160 km/h in the future can be declared at 160 km/h."

Liang Yuan couldn't help but feel nervous when he heard Liu Changhe mention the 25S model bottom.

The operating speed of 160 km/h is a very critical junction on the railway. After the train reaches this operating speed, it can openly claim that it is a quasi-high-speed railway. At that time, a traction nose with a cool shape and claim that it is a high-speed bullet train is no joke.

Since Liu Changhe was able to invite Zhao Tiemin to support the signing of the lease agreement, the relationship between the two parties must be extraordinary. As the Ministry of Railways' firm high-speed sect, Zhao Tiemin must be very familiar with the significance of the train operating speed reaching 160 km/h. Before the official appearance, Liu Changhe mentioned this matter frequently, which should be no reason.

But what does it mean? Liang Yuan couldn't help but feel his head getting bigger. Dealing with these middle-aged and elderly people is really exhausted.

Liang Yuan followed Liang Haiping and complained secretly.

Liang Haiping pondered for a moment and said with some distress: "Mr. Liu's expectations and encouragement for us are good, but I'm afraid that the Northeast Locomotive Factory will not be able to catch the strength of the Northeast Locomotive Factory."

"The operating environment of double-decker undercarriage in Democratic Germany is completely different from ours. The land area of ​​Democratic Germany is only equivalent to the size of Liaoning Province. It can be said that all trains are medium and short-distance operations, and the longest operating route will not exceed 6 hours' drive."

"In Democratic Germany, the double-decker bottom is pulled by a 243 electric vehicle, and the maximum speed will not exceed 140 km/h. I have been riding many times when I went to Democratic Germany to attend the exhibition in the summer. The comfort level is first-class at the low speed, but when it is close to the highest speed, the second floor of the car is shaking a little."

"In Democratic Germany, due to short operating mileage and high center of gravity, the disadvantage of high speed instability caused by double-decker bottoms will be weakened. For example, the t11/12 we are preparing to change the clothes, it takes 16 hours to travel to Peking. If the speed of the car bottoms is up, the passenger comfort level may decrease when riding for a long time."!~!
