Zuo Jiang returned home, the banquet had ended, his father Zuo Zheng and Song Dayou were still discussing warmly while drinking tea on the sofa, and Song Dayou asked when he saw Zuo Jiang entering the house: "Xiao Jiang, how is Kexin?" ”

Zuo Jiang said: "Uncle Song, Kexin is fine, she has fallen asleep." Seeing her mother Li Shuyuan and Zhong Lijuan cleaning up the table together, she walked a few steps to the restaurant to help, but asked Zhong Lijuan, who was smiling, to push her out.

Zuo Zheng saw that Zuo Jiang was pushed out by Zhong Lijuan, and beckoned to Zuo Jiang and said, "Son, there are your mother and Aunt Zhong in the restaurant who use you, come here, I'll ask you a question." ”

"What's the problem?" Zuo Jiang replied as he walked to the sofa opposite Zuo Zheng and sat down, his inquiring gaze on Zuo Zheng.

Zuo Zheng said: "I and your Uncle Song feel very good about the issue of building a safety standard line you raised just now, it is very innovative and operable, and after studying with you Uncle Song, we have decided to implement it in the whole sub-bureau as soon as possible." But what I don't understand is, how did you come up with the idea of building a safety standard line? ”

Song Dayou was also very touched by this question, so he said, "Yes, Xiao Jiang! Your dad and I have been working on the railroad for decades and I didn't expect such a good solution, but you are still a junior high school student! "The implication is that you, a junior high school student, have no contact with rail transportation at all, so it's puzzling to think of such a good solution.

Zuo Jiang said: "Uncle Song, in fact, I suddenly thought of this method when I heard you and your father talk just now, maybe an outsider can see things more clearly!" When Zuo Jiang proposed the construction of the safety standard line, he had already thought of a way to explain, and when he saw his father and Song Dayou asking this question, he was not in a hurry, and answered slowly.

Song Dayou said: "It is true that outsiders can see this statement more clearly, but you don't have any professional knowledge of railways and management technology at all, let alone any management experience, even if you see it clearly, it is impossible to put forward such a targeted professional opinion." ”

Song Dayou asked these questions exactly what Zuo Zheng wanted to ask his son, he nodded yes while looking at Zuo Jiang and said, "Yes, son, I'm also very strange!" ”

Zuo Jiang said according to the pre-thought rhetoric: "Uncle Song, my father has the habit of bringing newspapers to the house to read, I will flip through them when I finish studying, and the Songtie Workers Newspaper and the People's Railway Newspaper often publish some articles on the exchange of experience between various bureaus and units, as well as good experiences and good methods to solve some problems. I understand the importance of line quality to ensure the safety of railway transportation, just listened to my dad and you talk about the safety inspection activities, I suddenly thought of combining the two together, I didn't expect to say this idea, it was agreed by Uncle Song and my dad, I think this is a blind cat met a dead mouse! ”

Zuo Zheng was stunned when he heard what Zuo Jiang said that the blind cat touched the dead mouse, and then laughed and scolded: "You bastard, you said that you are a blind cat, then you and your Uncle Song are not dead rats?" Zuo Jiang's explanation was reasonable, and Zuo Zheng couldn't find anything suspicious at all, so he was relieved, but Zuo Jiang's last common sentence made him laugh.

Song Dayou also laughed and said: "Okay, that's right, I'm a dead rat and your father can't run away, I hope we can often run into your blind cat!" ”

Zuo Jiang scratched his head embarrassedly and said, "Uncle Song, I didn't mean that, really!" That's what I mean! ”

When Song Dayou saw Zuo Jiang embarrassed, he teased him and said, "Xiao Jiang, what does that mean and what does it mean, what do you mean?" ”

While talking, Li Shuyuan and Zhong Lijuan had already cleaned up the table in the dining room, Zhong Lijuan also had to help Li Shuyuan go to the kitchen to help her wash the dishes, Li Shuyuan didn't say anything, so she pulled her to the living room to chat, these words happened to be heard by them, and said to Song Dayou: "Old Song, I said how do you gang up with Lao Zuo to bully children?" ”

Song Dayou hurriedly waved his hand and said, "No, no!" It's too late for us to like it, how can we bully him, Lao Zuo, don't you say? Song Dayou kicked the ball to Zuo Zheng with a smile on his face.

Zuo Zheng had to say to Zhong Lijuan: "Sister-in-law, Lao Song really didn't bully Xiao Jiang, and I can't bully him, he is my son!" He laughed as he spoke, and his expression was clearly saying, it's normal for my son to bully and bully!

Everyone in Zuo Jiang pointed the finger at him, and quickly stood up and said, "Aunt Zhong, how could Uncle Song bully me, they are joking with me!" Speaking of this, he paused and said: "Uncle Song, Aunt Zhong, you talk first, I'll take a shower when I'm sweating!" As he spoke, he quickly ran back to his hut and got a change of clothes and rushed into the bathroom.

Zuo Jiang's run made everyone laugh out loud, and then Zuo Zheng and Song Dayou continued to talk about the issue of building a safety standard line. Li Shuyuan and Zhong Lijuan talked about the problem of children, and the woman was excited when she talked about children, especially the children were still very good children.

As soon as Zhong Lijuan looked up and saw that it was already 10 o'clock, she said to Song Dayou: "Old Song, it's 10 o'clock, let's go home quickly, let Lao Zuo and them rest early, Kexin is still home alone!" ”

Song Dayou didn't expect it to be so late in a flash, so he stood up and said goodbye: "Lao Zuo, we will talk about the issue of the safety standard line when we go to work on Monday, you should rest early!" ”

Although Zuo Zheng still wanted to keep it, but when he thought of Kexin's words of staying at home, he couldn't say anything, after the husband and wife sent away Song Dayou and his wife, Zuo Zheng said to Li Shuyuan: "Shuyuan, let's clean up and rest in a while, tomorrow our family will go to Tongjiang to see Xiaojiang's grandmother and grandfather, and take the morning car." ”

Li Shuyuan was very happy when she heard this, Zuo Zheng hadn't been to her parents for almost three months because she was busy with work, and she hadn't been there for more than a month, and she was trying to take advantage of tomorrow's Sunday to go, but she didn't expect Zuo Zheng to go too. So he asked casually: "Lao Zuo, why did you suddenly remember to visit your parents!" ”

Zuo Jiang said: "One is that I have been busy with work for a long time and have not visited them, and I don't want to go, and the other is that the construction of Tongjiang Futai overpass has been approved, and today Mayor Zhu called me to invite our family to Tongjiang as a guest, and I couldn't push it off, so I agreed." ”

Li Shuyuan also knows some things about the construction of the Futai overpass, and she is very happy to hear that the road bureau has approved the project, and she thinks that she will be able to go home tomorrow to see her parents and say: "Lao Zuo, let's go back tomorrow to bring something to my parents?" ”

Zuo Zheng said: "You just look at the belt, oh, by the way, I still have two bottles of good wine in the wine cabinet, you can bring it to our dad tomorrow." ”

Zuo Jiang came out of the shower and saw that his parents were not in the living room, he looked into the kitchen, Li Shuyuan had finished washing the dishes and chopsticks, was wiping the kitchen cabinets, returned to his cottage and took out the 500 yuan won by the competition, walked to the kitchen and handed it to Li Shuyuan and said, "Mom, here you go!" This is my prize money for winning the first place in the Provincial Mathematics Olympiad! ”

Li Shuyuan took the money and thought about it before stuffing it back into Zuo Jiang's hand: "Xiao Jiang, this money mom won't keep it for you, don't buy something if you like it, just don't spend it indiscriminately!" ”

Zuo Jiang didn't expect Li Shuyuan to give him so much money, and he couldn't help but get excited......

PS: In order to answer the questions raised by the book friend "Yishui Yangtze River", I was busy all this morning, contacting friends on the railway everywhere, but when I asked these questions, they understood what they meant but could not express them accurately, and finally, I contacted a friend who worked as an assistant engineer at the station, and she looked up the professional technical regulations and gave the answer.

Occlusion - On a single-track railway, in order to prevent a head-on conflict between two trains running in opposite directions at the same time in a section (between two adjacent stations), and to avoid a rear-end collision accident between two trains running in the same direction, the railway stipulates that the station attendants at both ends of the section must go through the driving contact procedures before departing from the section, which is called traffic blocking (referred to as blocking).

Locking - railway semi-automatic blocking equipment, a blocking machine at each end of the section, a special track circuit and an outbound signal, which are connected with wires to realize the electrical interlocking relationship between each other. The outbound signals on the station are controlled by the occlusion of this station, and only when the interval is idle, the attendants of the two stations have gone through the occlusion procedures, and the outbound signal can be opened after the departure approach is opened. When the train goes to the section, when the wheel presses through the track circuit of the departure, the outbound signal is automatically closed, and the two station block machines are in the state of "interval blocking", and then the two station exit signals can no longer be opened, which is locking.

Forcibly unlocked - the railway semi-automatic blocking, part of the manual operation, the other part by the train operation automatically completed, when the need to go through the approach cancellation procedures, when the approach has been arranged, pull out the start button signal to close by itself, the approach can be unlocked, called forced unlocking.

As for the passage station and the main road station, I made up the names of two small stations.
