Li Zhen and others were sitting in the high-class carriage, sticking their heads out of the window to look at the front of the car with great interest.
'Woooooo'
Thick smoke billowed out from the front of the car, and the unique whistle sounded.
'Boom, boom, boom'
The unique sound of the train sounded, and the twenty-car train began to move forward slowly.
People walked beside them and pointed:
“The speed is a bit slow.,”
"I don't know what the maximum speed this train can reach when running."
"One locomotive carries so many compartments. When the time comes to seat people and load cargo, it will be even heavier. I'm afraid the speed will have to be reduced a bit."
"You seem to have run two to three hundred meters away. I can still catch up with you at a trot."
"But it's okay to go slow. It's more comfortable than riding in a car if you do it steadily."
“…”
Li Zhen also felt that the speed was a bit slow. After running for one mile, his speed only reached about 30 miles. According to this trend, its maximum speed is probably only around eighty.
The speed of around eighty is still a bit slow relatively speaking. And this speed is also the limit of locomotive power that can be produced at this level of production today.
"It's true, the train runs fast only because of the headband."
Li Zhen sighed. By the time I ran five miles away, my speed had reached sixty. Li Zhen was a little dissatisfied, but everyone here enjoyed it.
"I think this speed is enough."
"Sixty miles is a constant speed. It has always been this speed, and there will be no traffic jams. There is no need to consider road obstacles. Just run forward."
"The highest should be less than eighty, probably around seventy at most."
"My only worry is that there will be too many stops here in the future, and we will stop and go. When the speed increases, we have to brake again. This wastes too much time."
"There is no way to solve this power problem. It seems that we can only set up fewer stations, and simply eliminate stations where they are not necessary."
"Gentlemen, I have a question that I don't know whether to answer or not."
"what is the problem?"
Everyone looked at Liu Jinghong.
Liu Jinghong pondered for a moment and said: "There is only one track, straight up and down. It was okay in the past, but what to do when we come back? Set up a crane at the terminal station and change the position of the locomotive? Wouldn't that be too troublesome?"
Everyone was stunned for a moment, then laughed again.
"That's enough."
"I think it's okay to be troublesome."
"There's nothing we can do about this."
"The locomotive is not heavy even if it is heavy. Use a crane to lift the locomotive from the front to the back so that the head becomes the tail. This can also be solved."
"The position of the carriage does not need to be changed. Just change the front of the car."
Liu Jinghong nodded thoughtfully: "Doesn't it mean that cranes must be installed at every terminal? This will really increase manpower and material resources, which is not cost-effective."
Li Zhen nodded: "I think the question mentioned by Jinghong is very good. Now the train is not mature yet. Everything should be done slowly. If you have any opinions, you should put forward and correct them. It is indeed a bit confusing to constantly make the locomotive become the tail. It’s too troublesome. Do you have any better solutions?”
Everyone was silent.
Since Li Zhen raised this issue, it must be solved and cannot be ignored any longer.
Jia Liping said: "Otherwise, the tracks at each terminal station should be built into a circular shape. When the train reaches the terminal station and keeps moving forward, it can make a circle and then merge into the original track, so that the train does not need to Turn around.”
"Dean Jia's suggestion is very meaningful."
"I think Dean Jia's proposal is a good one."
"It's okay, it's okay. Turn the track at the terminal into a circular shape, and the train can go straight forward and complete a U-turn."
"No, I think this suggestion is not good. Although there is currently only one track from Laoshan to Quancheng County, in the future, train tracks will be laid across the country. Do we need to set up circular track U-turns at all stations across the country? There are so many across the country Region, which station is the so-called terminal station?"
As soon as this was said, everyone fell silent again.
Li Zhen was also thinking, how could this train turn around
While everyone was thinking about it, the train had traveled dozens of miles and encountered a hillside.
When encountering a hillside, the speed suddenly dropped and the train began to climb. But climbing uphill with twenty carriages is not that easy.
The speed became slower and slower, and finally stopped. After stopping for a few seconds, he slowly moved forward.
Li Zhen and others were speechless with their mouths open.
"Isn't this power... too weak?"
"It's impossible to climb this mountain."
"It's over. In the past, the train track was only built to one county, but now it has been completely built from Laoshan to Quancheng County. There are many mountain roads and steeper slopes. What should we do?"
"If we can't climb up the slope, what should we do if the train is stranded in the deep mountains and wild forests? We can't even go back. The crane can't reach this place. If we can't get over this slope, wouldn't the train be useless?"
"What should I do?"
“…”
Everyone in the carriage stood up.
The manufacturers who produced trains were even more nervous. They stood in the corridor and kept looking out, stamping their feet anxiously.
Who would have thought that there would be so many variables in the future? You can't even climb up, what should you do
Li Zhen stuck his head out of the car window and looked forward. There was still a long slope up there. The locomotive was making an extremely sharp roar, like a bull that had exhausted all its strength and rushed upward.
The effect was there, the train did not stop completely, but was moving slowly.
But this is not possible.
When the train pulls people and cargo, it will be even heavier. What should I do if I encounter this guy again? To say it is stranded is to say it is stranded. The machine has its limits.
When Li Zhen was frowning, a young man named Zhan Youtian from the Mobile Academy suddenly screamed: "I have a solution!"
"any solution?"
"Alas, your method is useless. This is the limit of power. Needless to say, if the carriages are abolished or something, this is the only way."
"You can't even talk about reducing the slope. It's impossible. It's almost equivalent to a mountain reclamation project. It costs too much money and it's better to build a tunnel."
"Oh, there's nothing we can do about it."
Zhan Youtian's face flushed with anxiety: "I really have a solution. I thought of a way that can solve the problem of weak train power and also solve the problem of trains turning around. From now on, trains can travel anywhere and on any road section." Perform a U-turn. No crane required."
Everyone's breath froze, and they looked at him with some doubts and disdain.
Li Zhense asked: "Young man, what can you do? Tell me what you think."
Zhan Youtian took a deep breath and said excitedly: "Master Li, we can set up two locomotives. One locomotive in front and one locomotive in the back. When moving forward, the locomotive in front produces pulling force and the locomotive in the back produces pushing force. So The problem of power is solved as soon as it comes. When you reach the terminal and need to return, the tail becomes the head. The locomotive behind becomes the front, and the front becomes the rear. There is no need to make any U-turns or change the locomotive. It’s just that the car in front becomes the car behind, and the car behind becomes the car in front. The power problem is solved, and the U-turn problem is also solved.”
“…”
Zhan Youtian finished speaking. There was silence in the entire carriage, and you could hear a pin drop.
Everyone looked at each other and couldn't say a word.
Zhan Youtian blushed and said, "I, did I say something wrong?"
Li Zhen took a deep breath and looked at Zhan Youtian seriously: "Thank you for solving a problem that has trapped everyone. Thank you, young man."
'Pap-pap-pap'
Li Zhen took the lead in applauding.
Everyone in the entire carriage looked at the shy and blushing Zhan Youtian, and gave him the most sincere applause without hesitation.
The applause of "Hua Hua Hua" lasted for a long time in the carriage.
