Chapter 752: milestone

? "Woo..."
　　
　　 The siren of the steam locomotive sounded at Qingzhou Station, and people on both sides of the railway were crowded. Today's trial operation of the steam locomotive attracted many people from Qingzhou to watch the excitement.
　　
　　 Looking at such a prosperous scene, Xiao Ming was happy in his heart. He has missed the golden age of scientific and technological development in his contemporary country. Now he will not shame the country he rules.
　　
　　 For him, today’s steam locomotive trial operation is a historical piece of Da Yu country surpassing the West in terms of science and technology. In the future, Da Yu country’s new technologies will only continue to emerge, and it is just around the corner to fully catch up with the West.
　　
　　 "The emperor."
　　
　　 Lin Wentao is leading the trainees to do the final inspection of the steam locomotive, which is about to drive out of the city.
　　
　　 Xiao Ming and Pingyang Princess had already arrived in front of the steam locomotive. Behind them were officials of the Railway Department.
　　
　　 Stepping on the track under the foot, Xiao Ming asked: "Is this railway track laid in accordance with the established track standards?"
　　
　　 Lin Wentao was also a little excited today, he said: "The official has issued the emperor's track standards to the Railway Department, and now every Railway Department official remembers it by heart."
　　
　　 As if to confirm Lin Wentao's words, Princess Pingyang said with ease: "This track is divided into rails, sleepers, connecting parts, track beds and turnouts."
　　
　　 "The sleepers are divided into two types: wood and concrete. The two are laid apart from each other. The rails and bolts are made of steel, and the track bed with gravel is basically a qualified railway."
　　
　　 Xiao Ming nodded with satisfaction when he heard the words.
　　
　　Princess Pingyang seemed to be deliberately acting in front of Xiao Ming, so she said: "The track gauge of this railroad track is also exquisite. According to the standard, all railroad tracks are now standard rails with a width of 1,435 mm."
　　
　　 Said this, Xiao Ming praised; "Auntie has even memorized this track standard, and I am completely relieved."
　　
　　 has a variety of technical standards beyond this era, Xiao Ming naturally will not let the railway of Dayu country explore the standard width of the track by himself, and can directly come up with mature railway standards.
　　
After all, from the beginning, Lin Wentao’s steam locomotives were produced in accordance with this standard. However, the width of the rails in each country today is different. This is mainly to prevent other countries from being able to directly use each other’s railways when they invade, such as Russia. It uses a wider gauge than the European railway.
　　
　　 "The emperor can give me such an important thing to a weak woman, this is trust in me, how can I live up to the emperor's expectations." Princess Pingyang smiled like a flower.
　　
　　 An official from the Department of Railways took the opportunity to flatter and said: "His Royal Highness is really working hard for this railway matter. She has to patrol the railway every day, and the ministers are also sorry."
　　
　　 Xiao Ming only noticed that Princess Pingyang was darker at this time. He said: "When this railway line is opened to traffic, I will personally set a banquet for my aunt to celebrate!"
　　
　　Princess Pingyang was taken aback. In fact, since she came to Qingzhou, she has lived with trembling. This nephew seems to be gentle, but she is not merciful at all when she kills.
　　
The day when Zhao Wang and Zhao Yuanliang's father and son were executed by Ling Chi is still fresh in her memory. She used to be ashamed of Xiao Ming, so now she does not dare to think about anything wrong. She is dedicated to working for the royal family, just to have a glorious and wealthy one. The second half of life.
　　
　　 "Thank you, the emperor, I'm just waiting for that day." Princess Pingyang was delighted, and it was obvious that Xiao Ming was very satisfied with her actions in this matter.
　　
　　 As time passed, more and more people were on both sides of the railway, and they couldn't see the side at a glance. At this time, Lin Wentao said: "Emperor, the steam locomotive is almost ready, is it officially running now?"
　　
　　 Xiao Ming glanced at the direction when he came. At this time, officials such as Fiji and Pang Yukun also came here, and Princess Pingyang must have also notified them.
　　
　　 nodded, and Xiao Ming said, "Let’s start, let the people of Qingzhou and Aiqing witness the operation of the first steam locomotive in Dayu."
　　
　　 "Yes, the emperor." Lin Wentao responded, and then gestured to the platform.
　　
　　 There was a station officer holding a red flag on the platform. After receiving Lin Wentao's signal, he waved the small red flag in his hand.
　　
　　 Following his movements, the steam engine car made a loud siren again, and then the train made a "hum, hum" sound and moved on the rails.
　　
　　 Fiji, Pang Yukun and other officials came to Xiao Ming's side. After saluting, they craned their necks to look at the steam locomotive.
　　
　　 After the locomotive dragged the long car body and started to move, Pang Yukun exclaimed: "I didn't expect this steam locomotive to be able to drag such a long car."
　　
　　 Fiji also looked surprised, and he said: "Yes, but it's a bit too slow."
　　
　　 Xiao Ming smiled and said nothing. He was laughed at when the first steam locomotive was in operation, but in the end, the steam locomotive eliminated the traditional transportation of cattle and horses.
　　
Of course, the steam locomotive manufactured by Lin Wentao is not comparable to the first steam locomotive. After Lin Wentao’s test, the reciprocating high-temperature and high-pressure steam engine he installed is enough to allow the locomotive to run at 67 kilometers per hour. The speed of modern trains is very high, but it is already very rare.
　　
　　 And Lin Wentao is already developing a double expansion steam engine, which can use steam twice or even three times, greatly improving the thermal efficiency of locomotives.
　　
　　 Once this kind of steam engine is successfully developed, both the steam locomotive and the steam ship can be greatly improved in speed.
　　
　　 "吭哧, 吭哧."
　　
The steam locomotive was getting faster and faster after leaving the station, and the people on both sides of the two roads made exclamations at this time~EbookFREE.me~ Before this, many people were puzzled that this strange thing was used What they came for, now they finally understand.
　　
However, they who had never seen a steam locomotive were frightened by this scene, and the students of Qingzhou University who were in the crowd couldn't help cheering. This matter was equally significant to them, because it proved that they abandoned the Four Books and Five Classics. Correct.
　　
　　 It is the western businessmen who are more shocked than the Qingzhou people.
　　
　　 "My god, what the is this? What did I see in Dayu?" A young western businessman exclaimed, and beside him was an older westerner who was the father of the young man.
　　
　　 "This is science." The eyes of the young businessman's father flashed crazy.
　　
　　 The young businessman looked at his father. In his memory, his father was very knowledgeable. He continued to ask: "Father, what is this?"
　　
　　 "I don't know, but this must be an incredible thing. Maybe we should stay here to figure out what they are." The elderly businessman said solemnly.
