Zhang Jun was very angry when he was swept up by Lu Dongzi, and his eyes suddenly lit up when he heard Zuo Jiang say this. He just wanted to vent the evil breath in his heart, and didn't think about how a middle school student like Zuo Jiang knew this rule. said to Zuo Jiang: "Xiao Jiang, you wait for me here, I have to let you get on this train today, and after speaking, I went to the field duty room."

Zhang Jun asked the field attendant to find out the "Technical Regulations" to check, and sure enough, there was the rule that Zuo Jiang said, and now he had the bottom of his heart, so he called the traffic dispatcher when he picked up the phone on the desk. Due to his work, he is very familiar with the train dispatchers of the four dispatching stations, not to mention asking for a dispatching order to take the train, that is, begging the dispatcher to let the freight train stop for a minute at the small station through which it passes.

Zhang Jun did not use a special dispatch and centralized telephone, but used a dial-up telephone. After all, this is a private matter, and as soon as you speak on the phone of the dispatching station, all stations along the line can hear it, so that others know that the impact is not good. After a while, the phone was connected, and the dispatcher of the car dealership on duty today was his old acquaintance Han Zhongzhong, who turned out to be the head of the shunting area under him, and later transferred to the dispatching command of the sub-bureau as a dispatcher. Zhang Jun got to the point after greeting him for a few words, and Han Zhongzhong directly gave a command number without even asking what the reason was. That is, the dispatch order he gave at random allowed him to avoid prison, and he was sentenced to two years in prison for the mistake of dispatching and commanding in that "7.27" major incident, which is of course a later story.

Zhang Jun asked the field attendant to fill in the dispatch order and stamp the special seal of Songjiang Station, and then walked out with the dispatch order, just at this time Lu Dongzi came out of the train number room with a leather bag on his back. He greeted him and said, "Master Lu, you see this is a dispatch order to take a car, oh, and a ticket!" As he spoke, he took out the ticket from his pocket and handed it to him, "There's nothing wrong with it this time, right?" The look on his face was very proud.

After Lu Dongzi took the dispatch order and the ticket with an expressionless face and confirmed that it was correct, he folded the dispatch order and clipped it into his logbook, and then handed the ticket back to Zhang Jun and said: "Stationmaster Zhang, since the formalities are complete, let this kid go with me, but you must listen to me when you get to the car, otherwise, don't say that I will give him a ride down the road." Without looking back, he entered the field duty room.

The station is full of rolling stock, how can Zhang Jun rest assured that Zuo Jiang will go with Lu Dongzi alone, and when Lu Dongzi signs out in the field duty room, he will accompany Zuo Jiang to walk with him to the 2523 train that departs on 9 roads.

At this time, the arrival and departure line in the station is unusually busy, the arrival and departure trains are in and out, the shunting machine is going from south to north, and the wheels are rolling and the whistle is sounding, and it is also mixed with the broadcast notification of the train inspection operation. Zuo Jiang returned to this busy station after more than ten years, and suddenly felt like a world away.

After arriving at the 2523rd car, Lu Dongzi put the leather bag on the chair on the left side and said to Zuo Jiang: "Child, show me the backpack." Without waiting for Zuo Jiang to answer, he got out of the guard car to check the current car. Zuo Jiang felt a little crying and laughing for a while, thinking that this old comrade was too serious, why did he do such a thing.

Zhang Jun's attitude towards Lu Dongzi was also helpless, he instructed Zuo Jiang to listen to the words of the commander of the car, and the equipment of the guard car should not be moved, etc., so he said goodbye to Zuo Jiang and got off the guard car to go back to work. Zuo Jiang kept sending Zhang Jun to the passing platform outside the guarded car, and Zhang Jun stopped him when he saw that he was going to come down: "Xiao Jiang, don't come down, there are many cars in the station to pay attention to safety, don't make Lu Dongzi angry on the road!" ”

Zuo Jiang stood on the passing platform of the guard car and waved goodbye to Zhang Jun and said, "Uncle Zhang, don't worry, I will take care of myself, thank you Uncle Zhang!" ”

Seeing that Zhang Jun walked away, Zuo Jiang turned around and walked into the guard car, at this time, the train inspection staff had not yet come to work, and he was the only one in the guard car, so he carefully looked at the guard car. Before the rebirth of Zuojiang, the national railway has already canceled the use of the car, even the commander of the running car has been canceled, the car has become synonymous with the old antique, and today I see the new car in my heart There is a long-lost sense of intimacy.

The area in the guard car is not large, only about ten square meters, there is a lookout window on the left and right sides, it is the running car captain to look at the loading state of the goods and the driving signal in the operation of the train, there is a chair fixed on the floor in front of the window, one positive and one negative two directions, because the driving signal of the railway is located on the left side of the line, the chair on the left is the positive direction, the right is the opposite direction, this is due to the train marshalling needs to change the running direction frequently and decides, there is a small desk in front of the chair. There was a window in front of and behind the door, a fixed chair and a small desk in front of the window, and in the center was a winter heating stove, surrounded by iron railings. In the end, Zuo Jiang saw the wind pressure gauge above the front window and the emergency brake valve that could stop the train!

The handle of the emergency brake valve is painted with red paint, which is very eye-catching, and as long as the valve is pulled down, the train will stop in an emergency, and the accident can be avoided! Thinking of this, Zuo Jiang subconsciously glanced behind him, and when he saw that there was no one behind him, he smiled and stepped forward, carefully observing the emergency brake valve.

The braking system of the railway train is completed by the wind pressure, whether it is a passenger car or a freight car, each car is equipped with a set of braking system by a wind cylinder, after the completion of a train marshalling, the inspector will connect the air duct on each car when checking the vehicle, so that the whole train forms a large braking system. After the air duct of the locomotive is connected with the whole train, the air pump is used to fill the train, and when the pressure of the wind reaches 5 kg, the braking requirements are met (note: the pressure of the freight train is 5 kg, and the passenger train is 6 kg). Only the locomotive and guard cars have emergency brake valves on the freight trains, and the passenger trains have them in every car.

At this time, the train inspection staff began to operate, a person carrying a small hammer went to the car to check the lead seal on the wind pressure gauge and the emergency brake valve, Zuo Jiang had to let go to the side and watch quietly, the locomotive has begun to inflat, the current pressure gauge shows that the pressure is 3 kilograms, when the pressure of the wind pressure gauge reaches 5 kilograms, the brake test can be carried out.

Emergency brake valves are installed on railway trains for use in the event of a situation that endangers the safety of the train and people. The regulations on what kind of circumstances can be used to stop the valve are very strict, if the valve is stopped without authorization, it will be set as a general liability accident, of course, the person responsible is the person responsible for the accident, so the railway staff are very cautious in this regard.

When it was almost time to drive, Lu Dongzi returned to the car, he first opened the windows on the left and right sides to hang up the signal lights, carefully checked the wind pressure gauge and the emergency brake valve and the lead seal, pointed to the chair under the emergency brake valve and said to Zuo Jiang: "You just sit here, you are not allowed to move after driving, do you hear?" ”

Zuo Jiang hurriedly nodded and said, "I heard it!" ”

Lu Dongzi was quite satisfied with Zuo Jiang's performance, and took the signal to guard the car, and when he saw that the field attendant in front of him gave the signal to depart, he waved the green signal flag in his hand, and with a long whistle of the locomotive, the train started.

The 2523 times were section freight trains, and there was no pick-up operation at the intermediate station, and only a small station meeting car was stopped after more than an hour. Along the way, Zuo Jiang always felt that Lu Dongzi's eyes were watching him intentionally or unintentionally, which made him very depressed, so he climbed on the table and pretended to be asleep.

"Passage station, 2523 trains approaching!" The radio station in Lu Dongzi's hand came from the sound of the driver calling the channel, which made Zuo Jiang, who was already a little sleepy, suddenly feel energetic and pricked up his ears to eavesdrop.

After the driver called the channel station again, the voice of the channel station attendant came from the radio: "2523 passage stations 2 passes!" ”

The driver shouted: "2523 times the driver understands!" After that, Zuo Jiang felt that the train began to accelerate. Because as soon as you get out of the passage station, it is an uphill ramp of 24/1000, and the acceleration is to break through the slope.

After Zuo Jiang heard the information that the 2523 train passage station passed, his heart immediately became nervous, he knew that the 848 train from the opposite side was going downhill, and the accident would happen in 15 minutes!

At this time, the train has entered the passage station area, Zuo Jiang nervously climbed on the table and peeked at Lu Dongzi, he did not go out of the car Zuo Jiang had no way to pull down the emergency brake valve, originally as soon as the train entered the station, he should have gone out to the station attendant to the signal, but the tail of the train was almost to the position of the station duty room, he slowly took the signal flag to open the door and walked to the passing platform.

If you don't pull the valve, I'm afraid it's too late! Zuo Jiang saw that Lu Dongzi had just gone out, so he jumped and pulled down the emergency brake valve. At the same time as the piercing wind whistle sounded, the high-speed train slammed down, the speed dropped suddenly, the whole train made a metal grinding sound, and the huge inertia made Lu Dongzi hit the safety fence behind the guard car at once, and he was so frightened that he grabbed the protective railing tightly, and was almost thrown under the car.

The train finally stopped after taxiing for more than 200 meters!
