On the outskirts of Chang'an, Li Shimin and the others saw the sentry posts standing outside the hunting ground from a distance, and saw that the palace guards who came in advance had dismounted and waited at the door. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Li Shimin arrived at the door and got down from the carriage, when even a palace guard stepped forward to report: "Your Majesty, there is a very ...... inside Quirky stuff! ”

Li Shimin nodded and said, "I know, I came to see that thing." Lead the way! ”

When the guards saw Li Shimin say this, they didn't say anything more, saluted again, turned around and walked forward.

And they all got out of their chariots and changed their horses, and rode into the hunting grounds. Under the horse, it didn't take long to reach the place.

First saw the railroad tracks on the road, and the eldest grandson Wuji asked: "When did there be two more iron bars on this road?" ”

Although this is a royal hunting ground, these ministers did not come with Li Shimin, so they are also familiar with this place. Hearing the eldest grandson Wuji ask this, they naturally had doubts in their hearts.

"It's called a railroad track, it's a road." Li Tai explained: "The train that I will see later is on this middle road. ”

"Trains?" The crowd was puzzled.

"Ordinary vehicles, driven by horses, are called horse-drawn carts, and oxen-driven vehicles are called ox-carts." Li Tai said with a smile: "This car is driven by coal fire and steam, so it is called a train." ”

As they spoke, everyone had already arrived at the place, and from a distance they saw a behemoth parked on the railroad at that end, and a platform next to the railway, on which a few people were busy.

"Ouch, this must not be five feet tall." Fang Xuanling raised his eyes and looked: "This thing is really not small. It's quite long, much longer than a normal carriage. ”

Xia Hongsheng smiled, haven't you seen the carriage behind you yet.

"Father-in-law, this is the train." Xia Hongsheng stepped forward and dismounted, and everyone also dismounted and walked up to this simple platform from the steps next to him.

"Wow!" As soon as they went to the platform, everyone was stunned, and there was a section behind the far behind, and there were more than a dozen sections!

"It's so long!" Li Shimin couldn't help but exclaim: "Even those behind this are pulling people?" ”

"You can pull people, and you can pull goods." Li Tai said: "In the future, there can be special people and goods. At the moment, it is for testing, so there are a few sections in the back to pull people, and the rest to pull goods. ”

"Let's go inside!" Li Shimin was greatly interested, and asked again: "Can you go in?" ”

"Yes!" Xia Hongsheng immediately led the way, leading the people to the back, while introducing the passing carriage: "This is the front of the car, and the driver has to be in it, not only to see the road conditions in front, but also to react according to the situation." The latter is the driving force that drives the train to run. It's like a horse in a carriage - but instead of grass, this horse eats coal, and it's much stronger. ”

"That's what the virtuous son-in-law said about the steam engine! I'm going to take a look. Li Shimin walked to the side, raised his hand and grabbed the ladder and went up quickly.

Everyone also hurriedly followed, only to see that inside was a thing more than two people high, with various pipes connected, and a huge boiler connected to the back. Two people were shoveling coal under the boiler.

"Burning coal heats the water in the boiler, produces steam, the steam expands, pushes the piston along the pipe, the piston reciprocates, drives the transmission shaft, and drives the wheels to rotate through the transmission shaft." Li Tai briefly explained next to him.

As a result, everyone listened in a fog, looked at each other, and no one could understand it, so they had to pretend to nod.

When I got down from inside, I saw the wheels again, and I was taken aback again: "What a big iron wheel!" ”

Continuing to walk back, Xia Hongsheng pointed to a carriage passing by: "This carriage is filled with coal for the boiler in front." In the latter section there are large buckets for adding water to the boiler. Further back, there is the place where people sit. ”

"Oh? Check it out! Li Shimin strode over and went up by himself.

"It's pretty spacious." After entering, Li Shimin said, "There are still seats." I'll take a look...... There are three people sitting on each side of the row on the left and right, well, sitting face to face like this, taking advantage of a small table, it is also convenient to talk. ”

"How many people are seated in this energy-saving place?" Fang Xuanling asked.

"There are one hundred and eighteen seats in each section, and there are one hundred and eighteen people in each section. This is a shorter distance and does not have to stay overnight in the car. Li Tai replied: "The latter section is very far away, and if you need to spend the night in the car, it is not a seat, but a sleeper." This is only for experimentation, so it is done together, and when it is actually used in the future, a whole train can be seats, or a whole train can be sleepers, for people from near and far. ”

"So many people?!" Everyone was taken aback: "Pulling so many people, can you run?" ”

Look, it's lagging behind, isn't it, the mind is still stuck in the carriage stage!

"Can you still sleep?" Li Shimin said with great interest: "Go and have a look at the back." ”

Then he will go down.

"Father-in-law, these carriages are connected to each other, and there is no need to go down." Xia Hongsheng hurriedly said, and then took Li Shimin past the carriage, and at the end, he opened a thin door, and the next carriage passed.

When it came to the next section, there was a sleeper compartment inside, Li Shimin went in to take a look, Xia Hongsheng said: "A sleeper compartment has 60 beds, which can accommodate 60 people and stay overnight. ”

"Not bad! Not bad! Li Shimin was greatly satisfied: "Then after such a trip, won't you be able to pull more than 1,000 people?" ”

"If the carriages are all pulling people, that's true." Li Tai replied.

Li Shimin was suddenly very excited, hooked his throat, and said: "Just now you said that this train can run 120 miles in an hour...... It can pull more than 1,000 people...... Doesn't that mean that it only takes five or six hours for these more than 1,000 people to travel from Chang'an to Luoyang together? ! ”

"One hour and one hundred and twenty miles?!" Except for Li Shimin, who already knew in advance, the rest of the people were messy: "There are so many people still pulling!" ”

"Exactly!" "The speed of the train can actually be faster, and it will increase further in the future with improvements and improvements," Li said. At the moment, the speed is still a little slow, so the greater role is not to pull people, but to pull goods! ”

"Pulling goods......" Fang Xuanling was still surprised: "How much can you pull?" ”

"100,000 catties!" Li Tai said in a deep voice.

"What?!" This time, including Li Shimin, was also shocked.

"And that's just as much as this test train can pull." Li Tai said: "If it is really put into use in the future, there are special ones to pull goods, and there can be more than this." ”

"And more! God, how can this be done by mortals?! "A bunch of bigwigs all exploded.

100,000 catties! How many horses do you have to pull this?!

Oh my God!
