Luo Yonggang didn't wait to get off work at night, called the director of the office at the station, and called two young female conductors in the passenger section, and the group got into Lao Song's "taxi"

For Suifenhe, who shouted the whole city, the aborigines were simply familiar with each other, Luo Yong just saw that it was Song Jianjun, and said to Liang Haiping: "Manager Liang lives in the old Song family?"

Liang Haiping nodded.

"Has Manager Liang tasted Lao Song's craftsmanship?"

"I ate it at noon today, first-class, I haven't met a game that is more authentic than Lao Song in so many years. Liang Haiping said admiringly.

"Manager Liang, you also know that the conditions on our side are not good now, and the hotel and your big city must not be compared, why don't we go to Lao Song's side, I'll get some roe deer and wild boars, and let Lao Song take charge of the spoon, what do you think?"

Liang Haiping and the three of them were a hundred happy, and greeted Song Jianjun and the group returned to the compound of the old Song family. Although 87 is not the era of roe deer and wild boars running everywhere, it is not difficult to get one or two.

A few hours later, the group gathered around a table of game to feast, and there were many outsiders present, Liang Yuan could only say a word, let go of a qiē buried his head in eating and drinking.

Liang Haiping and Luo Yonggang refined the cooperation plan mentioned in the afternoon, and the two discussed that Suifenhe Station would come forward to organize a large collective loading and unloading team, and then merge the loading and unloading team into the big market to be established in the future, so as to ensure that the cargo transportation in the big market in the future will be loaded and unloaded in the first time.

The two sides of this cooperation are in agreement, the atmosphere at the dinner table is high, the dishes alone are changed twice, and they have been eaten until midnight, and Liang Haiping asked Luo Yonggang to help get three sleeper tickets for the return trip, and Luo Yonggang agreed to let Liang Haiping go to the station to pick it up the next day.

Early the next morning, Qilianshan went to the future construction site to investigate, and Liang Haiping and Liang Yuan came to the train station early to get tickets.

Liang Yuan looked at the three sleeper tickets of the Mudanjiang-Beiping 127 direct express train in his hand, and said to Liang Haiping: "The 127th time is to enter the Beijing train, Stationmaster Luo has made a lot of efforts, and the train will depart from Mudanjiang in the early morning, uncle, we have to leave Suifenhe this afternoon." ”

Liang Haiping looked at Liang Yuan and suddenly laughed and said: "Xiaoyuan, you still have time to sigh, if I go to the Sino-Soviet Friendship Market to buy some Soviet gadgets, I will go back soon."

Liang Yuan reminded Liang Haiping, and suddenly remembered that he didn't say goodbye, and threw all the things about the competition to the two loli, where did he dare to talk nonsense, and shouted Lao Song and went straight to the market.

The lights of Mudanjiang Station at night were bright, Liang Yuan stood on the platform of the station and jumped hard, moving his body that was stiffened by the wooden bench of the 22-type train car, and the short journey of 198 kilometers from Suifenhe to Mudanjiang was towed by the 68-type construction steam engine, and the 6609 train from Suifenhe to Harbin ran for more than 5 hours.

Liang Yuan let out a long breath, and just wanted to take a deep breath, the somewhat sad whistle of the steam locomotive suddenly sounded, accompanied by the start sound of Longz Longz, and the fine cinders poured Liang Yuan's mouth with the wind. Liang Yuan scolded in a low voice, and the image of the steam locomotive that he felt cool in his previous life collapsed.

After leaving the station, the three of them found a small place to have a simple dinner, did not stay for an hour, and boarded the 127 direct express train from Mudanjiang to Beiping.

Since the founding of the People's Republic of China, there is an unwritten rule of the Ministry of Railways, the Ministry of Railways under the Bureau of Railways will give the best locomotives and vehicles in their own management to the Beijing trains, until the end of the 80s, there are still a considerable number of construction steam locomotives in service within the Road Bureau, and as early as the early 70s, the Beiping Railway Bureau has realized the internal combustion of all locomotives in the tube.

After the three of them entered the sleeper car, Liang Yuan ran to the bathroom to wash his hair full of finely crushed cinders.

Liang Haiping looked at Liang Yuan wiping his wet hair and said with a smile: "127 is much better than 6609, in the past, my uncle went back to his hometown to visit relatives all 6609 times, and he had to stay on the train for a week when he went back." ”

"Well, it's from hell to heaven. Uncle, the matter of Suifenhe is almost decided, with the help of the railway, it is not difficult to build a market over there, I plan to let my aunt take the team formed by the family to take charge of the affairs over there. After a while, Uncle found time to ask Qi Lianshan to see if he was interested in coming to work with us, and it is really rare for a technician with such a level to receive people and things. ”

Liang Yuan bent down and continued to Liang Haiping while changing his slippers: "Uncle still remembers that I told you that I plan to merge the vehicle overhaul shop under my father's section, right?"

Seeing Liang Haiping nodded, Liang Yuan patted the hard sleeper under him and said, "Uncle, this kind of carriage is the latest 22A type car produced by Changchun Bus Factory this year (Note 1). It is a pity that it is far behind the average level of foreign passenger cars. Therefore, in 84 years, the state gave a World Bank loan of 60 million to Changke for the introduction of the British 25-O bus production technology, which was used to replace the current 22 car bottom after absorbing domestic production. At present, the latest 25-type car bottom of Changke has been rolled off the assembly line, and my dad and their road bureau will use the latest 25-type car bottom to replace it with Beijing's T12/13 times at the end of this year."

Liang Haiping asked suspiciously: "What does this have to do with the maintenance plant in Duanli, the factory in Duanli mainly produces shunting machines and ore transport vehicles, and it seems that passenger carriages have not been produced for more than ten years." ”

Liang Yuan smiled and said, "Uncle, listen to me." ”

"After the Ministry of Railways introduced the single-layer Type 25 underbody, given the large population of our country, there is a lot of pressure on passenger traffic. At the end of 85, the passenger car production plant in the ministry issued a "25.5m air-conditioned double-decker passenger train development bid", and the maintenance plant in this tender section also received it. Finally, Nanjing Puzhen Vehicle Factory officially won the bid to undertake the development of short- and medium-distance double-decker air-conditioned buses. Nanjing factory went to Canada to inspect a circle and then planned to introduce the whole, but unfortunately was vetoed by the above, the ministry means that the British 25-O type single-layer car introduced by the long-term passenger on the basis of the trial production of double-layer bottom. ”

Liang Yuan took a sip of water and continued: "Nanjing factory in accordance with the instructions of the ministry for two years, this year to get the double-layer car body out, some time ago pulled to Beiping, in the ministry's ring line to do testing, due to the unreasonable design and the quality of the steel is not good, the construction speed of 120 km / h of the bottom of the car can only run at most 100 at the moment, I heard that the south factory to pull the bottom of the car back on the stiffeners. ”

Liang Yuan, who has the memory of his previous life, clearly knows that the South Factory pulled back the double-decker car bottom and successively rectified it for 2 years, and at the end of 89 years it was barely put into operation as a tourist train, and the problems continued after the operation, and the South Factory was forced to be helpless in 91 years and could only resort to the Changchun Bus Factory that produced the 25-type single-layer car bottom, and the two factories concentrated on it for three years, and it was not until 94 years that the double-decker 25B type bus with stable performance was launched. Due to the lack of electronic anti-skid devices, the speed of the newly launched bus is only 120 km/h, and the actual operating speed can only run 110 km/h. It wasn't until the late 90s, after several minor overhauls, that the operating speed of the double-decker Type 25B with electronic anti-skid was increased to 140 km/h. At that time, the introduction plan of 200 kilometers per hour bullet train has been discussed in a boiling manner, and the large-capacity double-decker car bottom suitable for China's population and national conditions has no chance to continue to improve its development.

"Uncle, the double-layer bottom developed by the South Factory can be said to be a failure, the main reason is that the top thinks things are too simple, thinking that the double-layer bottom is like building a house, and the single-layer bottom will become two layers after one layer, which would have thought that although it is only a layer to add, the strength of the entire car body, bogie, air springs, braking system, wheelset, etc. It would be strange if the layman guided the insider's double-layer car bottom if it could be successfully developed. ”

Liang Haiping listened to Liang Yuan's words a lot, looked at Liang Yuan in a daze, and said, "Xiaoyuan, where did you learn all these things?"

"Uh" Liang Yuan was stunned by Liang Haiping's question, "I saw it in the library, there are a lot of books about domestic and foreign trains, and today Uncle just mentioned the broken carriage of 6609 times, and remembered the maintenance shop in the section, so I told Uncle so much." ”

"Uncle is just asking, Xiaoyuan, you continue" Liang Haiping said in his heart that this nephew drew a picture and got 50 million, and it is trivial to understand the knowledge of trains, it is normal for boys to like trains, guns, cars and other things.

Liang Yuan looked at Liang Haiping and said in his normal heart, it is estimated that the uncle remembered his shocking 50 million, and felt that it was just a trivial matter for him to understand the problem of the train.

Liang Yuan became more and more proud of his decision at that time, and said with a smile: "Uncle, take the 22-type car bottom we are riding now as an example, the 22-type hard seat capacity is 116 people, the soft seat capacity is 64 people, the newly developed 25-type hard seat capacity is 118 people, the soft seat capacity is 72 people, and the double-decker hard seat capacity can reach 158 people, and the soft seat capacity is 126 people, and the same group of trains can create 30% more benefits. ”

Note 1: The bottom of the car is what we often call a train car
