Erlian Railway Station is the last stop for Huaxia to enter Mongolia, and it is the north gate of Huaxia.

Because the rails in Huaxia are international standard gauges with a width of 1435 mm, while the broad gauges used in Mongolia and Russia are 1520 mm wide, which is 85 mm wider than the rails in Huaxia, when the train enters and exits Erlian Station, it is necessary to change the wheels in the machine shop here, so that the train can fly freely on the railway line in Mongolia and China.

The so-called wheel change operation, in professional terms, should be called the replacement of the running part, that is, the wheel and the part connected to the wheel, the body of the train car does not need to be replaced.

Tang Feng's dinner was eaten at the guest house of the Erlian Municipal Party Committee, and he was accompanied by a deputy mayor of the Erlian Municipal Committee. During the meal, Tang Feng said that he wanted to take a look at the train wheel change operation in the international wheel change warehouse, and this bold Mongolian man immediately agreed.

The international train rotation operation in Erlian Station has almost become a famous scenery of Erlian, and many leaders who came to Erlian to inspect almost have such requirements, so the deputy mayor was not surprised.

Under the leadership of the deputy mayor, Tang Feng entered the international wheel change library of Erlian Station at 8 o'clock in the evening, which is the largest wheel change library in Asia. There are three three-track rails in this several hundred meters long wheel changing warehouse, which are specially prepared for the wheel-changing trains.

The distance between the second and third rails of these three rails is 85 mm, and the distance between the first and second rails is the Chinese rail width standard, and the distance between the first and third rails is the Mongolian and Russian rail standards.

When Tang Feng entered the wheel change warehouse, the K3 train from Yanjing to Moscow had not yet entered the station. However, the railway workers here are already on standby, and as soon as the train arrives in the warehouse, the busy wheel change work will begin immediately.

Because the train has to enter and exit the warehouse, this wheel change warehouse is not closed, and the cold air pouring in from both ends of the wheel change warehouse makes the temperature in the entire workshop only maintain at minus seven or eight degrees. It was in this bitterly cold environment that these respectable railroad workers changed the wheels of the trains, and they did not make a mistake for 57 years.

At 8:37 p.m., the K3 international express train from Yanjing slowly drove into the wheel change garage. Although this train has a K prefix and is a fast train, it is not like the orange-red body of the domestic fast trains with the K prefix, and the body of this train still retains the most primitive kind of green, which is the so-called green car.

Although it is a green car. This is the K3 train, but it has the reputation of "China's first train", and it is a veritable international train with the highest high-end service.

After the car slowly entered the wheel change garage, the locomotive stopped before the stop line, and then the railway workers on both sides of the train tracks began to get busy, first loosening the relevant connecting screws, and then lifting the train car to a height of about two meters above the ground with the help of a hydraulic lift. In this way, the bottom of the carriage can be completely separated from the running part.

A car will be lifted by four orange-red hydraulic lifts, with passengers inside the train car. They don't get off the train, so the passengers in the carriage gather in front of the windows to watch the wheel change.

At the bottom of each carriage there are two running sections, which stay on the narrow gauge when the carriage is lifted, while at the bow of the train, the prepared broad gauge running section is pushed by the tractor. Begin to walk backwards with the walking part stranded on the narrow track.

The narrow-gauge runners will be topped one by one, and soon, all the narrow-gauge runners will be pushed up to the rear of the train, and at the bottom of the suspended train carriages, the broad-gauge runners will be left.

This time. The railroad workers began to fix and correct the position of the broad-gauge running part with various tools, and when the position of the traveling part was determined to be correct, the lifter would put down the suspended train, and then the railway workers and masters connected the carriage body and the running part again, so that the whole wheel change work was completely completed.

This process lasted for about an hour, and the entire wheel change was complete when the train left the garage under the traction of the newly replaced coal-fired locomotive. The newly replaced train carriages will be pulled out of the country and into Mongolia under the traction of the new nose.

In fact, in addition to the locomotive, this K3 train has a total of 15 car formations, but only 11 of the carriage formations that need to be replaced by the running department, and the remaining four carriage formations are domestic rotary formations. Of course, when the train arrives at Zamyn-Uud station in Mongolia, it will continue to walk with several cars in Mongolia.

Tang Feng had long heard of the international train wheel change operation, but he had never seen it, but this time he finally saw it, although the whole process was full of steel collision noise, but Tang Feng felt that this kind of work was really amazing.

As the saying goes, if you have seen it, you have it, this time I watched the wheel change operation of an international train up close, which made Tang Feng feel less regretful, which made Tang Feng's mood very good.

Early the next morning, Tang Feng drove into the vast Inner Mongolia prairie, which will become Tang Feng's main battlefield in the next period of time.

The reason why he chose to be near Erlian was because Tang Feng had learned through the information obtained by Old Man Kang that this large area near Erlian was a weak area of the national geological survey. Although more detailed geological surveys have been done before, the real mineral resource exploration has not been done in place.

There are more than 330 kilometers between the 2nd Company and the Ximeng, and from the 2nd Company to the west, a large piece of the national border suddenly protrudes to the north, so the area north of the connecting line between the 2nd Company and the Ximeng is a vast area with a length of more than 300 kilometers from east to west and an average width of 140 kilometers from north to south.

Tang Feng planned to set up his battlefield in this large area this time. The area of this area is more than 40,000 square kilometers, almost as big as the top two Qiong Islands, which is enough for Tang Feng to toss vigorously.

This large area is under the jurisdiction of Ximeng, and although Ximeng also has one of the best lignite coalfields in the country, such as the Shengli Coalfield, Tang does not mind building a world-class open-pit coalfield with more abundant reserves in the northwest of Ximeng.

The reserves of the Tunguska coalfield are so amazing, even if you move one-tenth of it, it will be enough for China to use for decades! (To be continued.) )
