First of all, the place of Yangquan, Baidu knows that it is the name of the Republic of China, and it used to be called 'Yangquan'.

Why not mention it. Because first, the division of this place at that time was very chaotic, belonging to Meng County and Pingding County, but on the whole, it was the oldest coal and iron production area in Shanxi. And there are indeed documents that refer to this area as 'Yangquan'.

Second, I want Zhengyangzi Yu Shenxing to repair the 'Zhengyang Line', in order to make up this stalk. So it's not verbose.

Since some readers feel the need to explain it, then I will change the Yangquan in the previous article back to 'Yangquan'.

In fact, I personally think it's unnecessary, which is not conducive to the reader's understanding.

Then there is the issue of the Zhengtai line.

This section of the road is a total of 1560 miles, and the friction of the track is small, the energy is wasted, and it is not bumpy. The pull provided by the same horse is naturally fast on the rails. Therefore, it is not a problem for the railcar to run the whole distance in one day.

And we don't want to run trains, just run railcars, and it is completely enough to use the original Jingcheng Road, and there is no need to open mountains and split rocks. Shanxi's iron smelting is very developed, and it is only a matter of market.

To produce more than a hundred miles of pig iron rails, eight hundred to a thousand tons of iron is enough. This is just a year's pig iron output in Shanxi during the Zhengde years. The Jin merchants worked a little harder, and it was no problem at all.

In addition, it was not until the end of the 19th century that Europe evolved from pig iron rails to steel rails. And before the advent of trains, the railroad carriages had been running on the tracks for a hundred or two hundred years, so there were no technical problems at all.

By the way, China's first railway was built from Mentougou to Fuchengmen to transport coal. Because Lafayette was afraid of startling the dragon vein, he did not use steam locomotives, and used horse-drawn trains until the end of the Qing Dynasty.

Take 10,000 steps back and say, Zhao Hao is fooling Lao Xi'er, of course, he is saying it simply, blowing vigorously. Tie them to the chariot and let them contribute to the infrastructure of the Ming Dynasty. You can't just put it in trouble, right?

Before a monk writes, he must first study it carefully and then consult a professional. Professionals think it's feasible, we dare to write.

(The monk's book group is full of talents...... ）、

Finally, I ask everyone to discuss rationally and not be cynical as soon as they come up. Even if the monk makes a mistake, it would be nice to correct it......

Above. And ask for a monthly pass~~
