Xiao Niangpi found that the beds in the sleeper carriages were all covered with snow-white bedding and pillows. They felt very clean and very good.
She climbed up the ladder to the upper bunk and then tried to lie down.
Well, it's really good.
When sitting, the backrest fits the curve of the back very comfortably.
You can lie down with a pillow and cover yourself with a quilt. The bed is also soft and suitable, so comfortable that you don’t need it. With this sleeper, you can travel happily even if the railway is built far away.
Chen Ping smiled and said: "Madam, these sleepers belong to the second-class sleeper carriage, also called soft sleeper. The bed is soft. There are also third-class sleeper carriages called hard sleepers. Although they are also in tandem, they have three floors, middle berth and upper berth.
, cannot sit up, can only barely turn over and get up and down. At the same time, the width is only 70 centimeters. The price of that ticket is lower."
The little girl smiled and said: "I think this second-class carriage is very good. It feels very comfortable. You can lie down and look at the scenery outside the window, which is really a pleasure. You said this is a second-class carriage, is there a first-class carriage?"
Chen Ping said: "Of course, there is a passage on one side of the first-class carriage, and six double boxes on the other side. There are beds and separate bathrooms. The special-class carriage is a special car, and one carriage is an independent space with a bedroom and a living room.
.These two types of carriages are still being modified. They were not caught up in this trial run."
"Wow, that's as comfortable as at home. It's great." The little girl was immediately looking forward to the special car.
Lin Yueru also asked: "How many people is the capacity of the special car?"
Chen Ping said: "I'm not sure, after all, I haven't come out yet. However, at least it won't be worse than the VIP cabin on the clipper ship. The three ladies and maids can definitely accommodate it."
Lin Yueru said with fascination: "It would be great if all the provincial capitals of Ming Dynasty built railways. We could travel everywhere in special cars. It's fast and comfortable. It's great."
At this time, there are very beautiful mountain views outside the window, and the train has entered Xishan Mountain. The scenery of Yanshan Mountain is pleasant in summer, and the temperature on the mountain is lower. The mountain breeze blowing in from the open window is very cool.
Xiao Niangpi suddenly thought of something.
"By the way, if this train runs in winter, does it have heating equipment? Otherwise it will be too cold. Can it have a fan in summer? If not, after a while, in the dog days of summer, and the car body is made of steel plates, will it
It won’t be as hot as a steamer.”
Chen Ping said: "Madam, each carriage has a bathroom and a boiler room, which can provide boiling water and washing water at any time. The boiler can drive the radiator in winter, and it will not be cold in winter. The temperature inside the car will not be lower than 18 degrees.
"
Lin Yueru immediately asked: "What if it's summer?"
Chen Ping said with some shame: "At present, we are still studying the cooling methods in summer. There are currently several ideas, but none of them have been concretely determined."
"One is to install insulation materials in the interlayer between the roof and the car wall, and the other is to use a small fuel steam engine as power to forcefully ventilate the cabin. The most radical method is to install a straw water curtain air conditioner in the ventilation system of the cabin.
Mouth. This method has the best cooling effect and can lower the temperature by more than ten degrees, but it will make the car very humid."
At present, straw water curtain air conditioners have begun to spread in new cities. The principle of this thing is similar to that of modern air conditioning fans. They are still used on a large scale in India.
The principle is that the top of the machine is a water tank, and the front part in the middle is a straw curtain, and the water slowly leaves from the straw curtain. Behind it is a fan driven by a Kotlin engine that burns kerosene lamps as the power source. The bottom is
Kerosene tank. There are four universal wheels at the bottom of the machine, which can be pushed and moved.
The fan blows the straw water curtain from behind and sprays cool air forward based on the principle of evaporation and cooling.
This kind of fan powered by Kotlin external combustion engine has already appeared in the 18th century and was widely used in Europe in the 19th century. There is currently a listed company in Ming Dynasty that produces this kind of fan. For details, please see the previous article. This kind of fan is also
Three wind speeds and shaking head can be realized through mechanical design.
Currently, Beijing is very hot in summer. There is a huge demand for refrigeration equipment.
Yang Fan installed this kind of Kotlin fan with a straw curtain and made a Ming Dynasty version of the air-conditioning fan. In the days when there was no real air-conditioning, this thing actually worked well. But if you blow it for a long time, you will easily get rheumatism.
Yang Fan did not allow Xiao Niangpi and Lin Yueru to use this kind of water curtain air conditioner. It was too humid and not good for pregnant women. Yang Fan had a real air conditioner in his bedroom. It was powered by photovoltaic panels.
Xiao Niangpi and Lin Yueru don't have to worry about getting too hot at home in the summer. Besides, there is a beautiful mountainous area behind the new city, and there are many places to escape the heat.
This knowledge is also the key to their ability to realize the issues of temperature control in different seasons.
The train roared all the way out of the mountainous area and entered the plains of Huailai County.
Everyone on the train suddenly felt that the train seemed to be slowing down, and the speed slowed down. They looked at each other, and they didn't know why. Since this was a trial run, all the stations along the way did not stop. They went directly to Zhangjiakou.
"Look, look, what is that? It seems to be a stone tablet." Chen Guanya, the headmaster of Xinghe Academy, exclaimed.
At this time the train slowed down.
We arrived at Tumubao Station, but we didn’t stop, we just drove past slowly.
Not far after passing the station, a huge stone monument appeared in front of us.
"The Tomb of the Fallen Soldiers in Tumu Fort," Chen Guanya murmured.
For a moment, the whole train was silent. Everyone took off their hats, saluted, and bowed their heads in silence for a minute. They all knew that this was the reason why the master stayed at Tumubao for three days on his way to the expedition.
The bones of these rare soldiers who died for the country have been abandoned here for two hundred years. Yang Fan led his army to dress them up, bury them, and lay them to rest. He also set up monuments to commemorate them.
The leaders of Yang Fan's system all know that what the master values most are the heroes who sacrificed their lives for the country and the people. The Heroes' Temple in Xincheng enshrines the nameplates of servants and officers and soldiers who died in previous battles. Every year during the Qingming Festival, the master or Song Yingsheng will preside over it.
Sacrifice.
After passing Tumu Fort, the sun set and it soon became dark. Carbide lamps were lit in the carriage. A faint smell of gas filled the air. It was a bit pungent.
But, there is no way. There is no electrical system for lighting in this era.
In the evening, the train finally arrived at Xuanfu at eight o'clock, and then arrived at Zhangjiakou City, not far from Xuanfu, at 8:15.
The ladies got off the bus at Xuanfu and checked into the best inn.
This is the Tongfu Inn with a history of a hundred years. The entire inn has been taken over.
The reason why we did not get off at Zhangjiakou is because Zhangjiakou was burned to ashes. So far, only the broken walls, broken bricks and tiles have been removed from the city. The reconstruction of the city has not yet begun.
There are open spaces within the city walls, which are currently used as open-air material warehouses.
