"Boom-boom-"
The speed started to increase.
"Boom-boom-boom"
The operator yelled, "Fire up."
"okay"
The two men shouted, shoveled the cinders and began to add them to the stove.
'Woooooooooo' The white smoke is getting thicker and thicker.
'Boom, boom, boom, boom'
The speed of expansion and contraction of the crank connecting rod suddenly accelerated. Wheel speed also started to increase.
Now it has accelerated to 15 kilometers an hour, which is considered a complete start.
And when the locomotive exceeded the speed of twenty kilometers per hour, the locomotive suddenly burst out with more power, and the speed suddenly surged.
Thirty kilometers.
Forty kilometers.
Fifty kilometers.
After traveling about ten kilometers forward, the train's speed had increased to sixty kilometers per hour.
Cars always followed closely on both sides.
Li Zhen sat in the car and looked out the window and said, "Ask me. Can you continue to speed up?"
Immediately, someone stuck his head out of the window and shouted at the locomotive: "Master Li, can we still go faster?"
The operator shouted back: "It's that fast. You can only keep adding fire, but there is a process of burning."
When the people along the way saw this scene, they had some inexplicable feelings in their hearts.
"Is it that fast?"
“A road was built just for it, but it’s not as fast as a steam train?”
"This is only 60 hours, right? It's a bit slow."
"It's too slow. I thought a road was built specifically for it. After all, the speed is about the same as that of an airplane."
"Oh, what a waste. This guy eats so much coal and only has this speed?"
"That's no use. Might as well drive a car."
"I heard that in order to build railway tracks, they built bridges in the mountains and forests. They almost had to build tunnels. But the speed is so low."
“…”
Everyone was really confused and didn't understand why a road had to be built for it at such a low speed.
In fact, the speed of 60 kilometers per hour is not low. Strictly speaking, it is still very fast. But they didn't know that the train would be hauling dozens of carriages.
After traveling a distance of more than 20 kilometers, the train reached a speed of 80 kilometers per hour. Li Zhen murmured: "It's not as fast as expected. :"
"Yes, the ideal train, even if it tows twenty carriages, should be able to reach at least seventy kilometers per hour. But this is just a locomotive. It has been driven for dozens of miles, and the speed has only exceeded eight 10. It’s different from what I imagined.”
Ma Jianbin answered, with a look of disappointment on his face.
Little did they know that this was already a miracle. This has broken through too many technologies.
Ten thousand years ago, when the first train was built, it moved at about the speed of a snail. Even decades later when train technology has matured, the common train speed is still 50 or 60 kilometers per hour.
The train speed actually exceeded 100 kilometers per hour only after 2000 AD.
Under conditions like New Kyushu, it was already a miracle that the speed of the first locomotive quickly exceeded 80 kilometers. It can only be confirmed from the side that the development speed of steam power in New Kyushu far exceeds the level of 10,000 years ago.
Who allowed Li Zhen to stand on the shoulders of giants and see the world
'Boom, boom, boom;'
The sound is huge.
Li Zhen was so shocked that he couldn't bear the shock. He said to Ma Jianbin in the car: "Can you go back and make suggestions to see if the power of this locomotive can be increased? By the way, when designing the carriage, the first section It's a locomotive, and the second section seems to be a carriage specially filled with water. Judging from this situation, the steam locomotive boils water very quickly. You have to constantly add water to the power unit so that it can always maintain power."
Ma Jianbin nodded and took note.
Li Zhen added: "There is no need to go to the front. There is only the railway in front, and the car road is too desolate. The train can run eighty on the rails, but the car cannot follow and run eighty in the wilderness. It is very dangerous. Go back."
"yes."
Immediately the lead car began to slow down and turn back. The convoy also began to turn back.
The train continues to move forward. We have to drive all the way to Licang County Station before stopping.
There are many stations along the way where specialized personnel register data and record all the information about the train passing by.
Not long after Li Zhen and the others returned to Dafengtai Station, the locomotive had already arrived in Licang County. The total length is only a few dozen kilometers, so it won't take long.
As soon as they entered Licang County, the operator saw someone waving a red flag next to the track, which was a signal to start slowing down and stopping.
The operator pulled the switch on the spot, cutting off the steam energy.
'woo woo woo woo-'
As soon as the power transmission was cut off, the steam was immediately discharged from the chimney. A howling sound resounded throughout the land.
Extremely harsh.
But the train is still sliding forward. The front of the train is too heavy. At a certain speed, the inertia is very large.
There are mileage signs installed in advance on both sides of the railway track, and there is a sign every 100 meters.
The moment the operator closed the gate, he immediately began to calculate the speed of the train sliding in inertia. This is also data that must be recorded.
After the gate was cut, the train flew forward for a distance of two kilometers, and the speed decreased from 80 to 60 miles. People can't help but be shocked: "No wonder special rails are used. When the train slides on the rails, the resistance is really much smaller than on the road. After sliding for two kilometers, the speed is only reduced by 20 per hour. So let's put it this way If we come, it’s actually not impossible to tow twenty carriages.”
The rails are very smooth. Really smooth. It even gives the impression that it will move forward as soon as you push it with your hand.
This is the extremely low resistance that occurs when the steel wheel is on the rail and the two meet.
The operator vaguely saw the anti-collision wooden beam five kilometers ahead. That was where the track was repaired. It had to stop there. If there was no track further forward, the vehicle would overturn. So a lot of tough wooden beams were used across the rails.
The operator took one look and quickly started to pull the switch.
Pulling the brakes hard, there was a tooth-aching friction sound on the rails.
'Woo, squeak, squeak'
On the railway tracks, sparks were everywhere, and sparks kept flying out.
The observers on both sides of the road raised their eyebrows and quickly recorded this phenomenon.
But what is a bit alarming is that the brake does not have much effect. The resistance between the rail and the steel wheel is extremely small, and at the same time, the friction is also extremely small.
The operator was a little scared. He kept looking down at the speedometer and looking up at the distance ahead.
The observers on both sides became anxious and kept shouting: "Brake. Brake!"
The operator was also anxious: "I'm braking!"
Doesn't work.
How can it be as easy for a train to brake as for a car
No one expected that when the train brakes, jamming the wheels seems to have little effect... and the damage to the wheels is also extremely high.
When it was still 500 meters away from the anti-collision wooden beam, the locomotive was still traveling at 38 miles per hour.
The operator was so anxious that he stamped his feet and shouted over his shoulder: "I'll tell you to jump later, so just jump."
The two coal filling workers were also scared. What was going on? They even jumped out of the car. This brake is too bad.
At two hundred meters. The speed dropped to thirty miles per hour.
The operator knew that he would definitely hit, so he yelled: "Jump!"
Without any hesitation, the two shirtless men jumped down, one on the left and the other on the right. After landing, they quickly rolled on the ground several times. Their bodies were covered with wounds cut by gravel and dripping with blood.
But they didn't care so much. Everyone looked at the front of the car that was still rushing forward in horror. After a while, the operator jumped down with a large pile of documents and was covered in blood.
After a while.
'Bang' sound.
Wood chips were flying, and everyone was dodging quickly and screaming.
But he saw a dozen wooden beams as thick as arms tied together in front of his head, all broken by the impact and flying all over the sky.
Finally, when it encountered the last layer of waist-thick wooden beams, the train came to a halt. It stopped there and made a constant sound of "woo woo woo" and emitted billowing steam.
All the technicians in Licang County were stunned and looked at each other.
"The brakes are a problem..."
