Looking at the people in front of him, Yang Heng felt a little embarrassed, that, am I too irresponsible, I didn't care about it after I handed you the task, you did it so well, and there was such a thing with a super friction coefficient, you actually pushed it away.

"Xuewen nephew, you can rest assured, I promise that I will smooth it out within three days, what, you still have requirements, you can also, you can rest assured."

This is the third uncle, the mountain sound of patting his chest, since this is the case, then I will come and see it in three days, but Yang Heng will not be idle in these three days, he has to study how to let five horses pull the car together, and it is the carriage of the train. Is it better to have two horses in the front, or two horses in the back, how did the movie that made what flew be pulled? But it's not five horses on it, forget it, don't think about it, let's talk about it then, it's just a test, and it's not a permanent horse to pull the train, it's not reliable, isn't it, and professional things, let professional people do it, this horse is not something you can drive.

…………

After three days, it finally arrived, Yang Heng came to the railway again, only to find that in the protruding stone, it was really paved with loess, and there were two railroad tracks left on it.

"Big nephew, what do you think, but I think that this track route is shorter, and it is more troublesome to repair, if you run, it is estimated that the horse has not yet run, and it has already come to an end." The third uncle has some regrets.

yes, this horse-drawn cart has just run. Then you have to slow down and brake. One carelessly. It will run across the line, although there will be no car crash and death, but the carriage will derail, the horse will be injured, that is certain.

"Well, don't worry, Third Uncle, if the verification is suitable. Then you will continue to repair, at least to reach the vicinity of Chang'an City, so that there are more than 30 miles of road is OK, at that time, we will transport goods, is to let people sit on the head for sightseeing, and the picture is fresh, now, Da Ge, it depends on you. ”

"Don't worry, Xiao Langjun. Isn't it just five horses to pull it, this little meaning? I'm sure I'll be able to catch it properly. Da Ge was also very excited when he saw this scene, such a big car, and even a special route, was still running on the railroad tracks, which was exciting to think about.

", remember, after you get up at this speed, you have to lower down and then stop, otherwise there will be a derailment and there will be injuries to the horses."

As these veterans of the Yang family, it is not an important thing, Yang Heng basically does not ask them to do things, they are all responsible for their favorite messes, and they bragging and chatting with some newcomers when they are idle, but why did Yang Heng call him again, because after thinking about it, Yang Heng is still very relieved about these old people.

Sure enough, Uncle Da was reassuring, and the five horses were properly placed in a while, "Xiao Langjun, are you starting?" "Launch." Yang Heng gave an order, "Drive." Uncle Da shouted.

Then I felt the chassis of the car under me slowly begin to turn, and it swayed, what a familiar feeling, and the wonderful sound of the iron wheels rubbing against the rails, and now what is missing is the loud whistle, and the sound of deflating, but there is more of the sound of the horse's hooves, "stomping, stamping," and the horse's chirping "Herod......"

"Big nephew, don't say it, this thing is really good, it's fast, and it pulls a lot, you see, we have so many people on it now, this horse-drawn one is so easy, it's much lighter than a carriage, and it's even stable, if there is a shed, it would be even better."

Why did the third uncle say this, it turned out that this car is still just a big flatbed, a flatbed car more than 40 feet long.

"Well, uncle, let's install a carport, and even install glass, so that people can look outside, and you can also sightsee."

"How expensive is glass, just a small piece, a lot of silver." Wang Feng on the side interjected.

How many people are pulled on this car, there are only more than ten people at present, and this car, if it is loaded into the carriage, it may be able to pull more than 30 people, and it is a face-to-face round seat, there must be tea waiting, and even other things, this belongs to the special carriage, this is Yang Heng's current plan, ordinary people, don't think about it now, they are a group without money, just wait for the real train to come out, and they will have their seats.

"So, third uncle, give you half a year, according to this standard, how about going south to the location of the station we booked outside Chang'an City, and to the north, to the princess's village." Cheng, eldest nephew, I promise to complete the task.

"Where's the fifth uncle?" "Your third uncle is finished, I can't finish it," "You two, continue to build a new car chassis, but it's not like this, this test has been done, what are the shortcomings you know, so, we have to follow my original drawings to come, to use springs, although love is two wheels in one, but on one side of the two wheels, specific on the drawings, how to reinforce, how to be strong that needs the two of you to grasp, my requirement is, according to this running method, At least one year without failure, and it should be easy to overhaul and replace bad parts. ”

"Don't worry, owner, we will definitely do a good job, so what about this car, do you want to dismantle it?" "No, this will never be demolished, this is our construction history, and it still needs to be used now, and when it is decommissioned, we must have a special place to display them, and even write a description for people to visit." At this time, Yang Heng had already begun to fantasize that maybe in a few hundred years, this car would be changed to a train, but people didn't want to change it.

"Da Ge, the next thing you have to think about, there may be two carriages in the future, then five horses may not be enough, there will be brakes on it, you also have to find a whole set of ways, this horse-drawn carriage way, maybe it will last a few years, maybe it will be a lifetime of sightseeing short train, remember, you have to use the fastest time to train a few apprentices out."

"Don't worry, Xiao Langjun, I'll leave it to me."

Yang Heng's idea is very simple, now with a horse, it has been a successful test, if the real steam locomotive has it, maybe there will be a special horse-drawn train with two or three sections, which is used for tourism, then it may be a face-saving thing.

"Big brother, big brother, we're here, why didn't we have such a fun thing?" This group of children, and who is it, it turned out to be Changle and Yuzhang, and the two of them also came to see the excitement.

Well, this group of children can't be seen as ordinary children, maybe they will have new ideas, "Everyone sit down, don't fall, this fall is very dangerous, wait for a round trip, talk about your feelings, and your suggestions." ”

Okay, Yang Heng directly assigned them tasks.

"Big brother, this is what train you promised Grandpa Huang, but why didn't I see the fire?" This is not only Yu Zhang's question, but even the children are looking at Yang Heng with blank eyes, wondering how he can explain it.

"This, it's a semi-finished product, don't you see that it's a horse that pulls the car, the train train, it's naturally a fire car, but I haven't developed that kind of power yet, it will take at least three years to succeed, you can rest assured, I can promise the emperor to cause it within five years, at that time, it was not such a car, but ten or twenty cars longer than this car."

"Oh, that's so exciting, by the way, big brother, is that speed still so fast?" "That's happier, one day and one night, at least more than 600 miles."

Yang Heng can't say too exaggerated, but the speed of more than 30 miles per hour can still be achieved, otherwise it is still a traverser, however, it is also possible to travel at a speed of 60 miles per hour, but the safety issues along the way should be considered, don't have anyone on the railway at any time, it is this test, Yang Heng also specially arranged a few guards on horseback to run in front, just for fear that someone would bump into it.
