Chapter 185： Train selection

Five kilometers a day, An Kai's speed is really scary.

If this is said, others can listen to it as a ghost story.

But it is a pity that systematic people are so headstrong, and more importantly, no one in the shelter would feel that this is wrong.

The system is so powerful and vague, it can make all things around Ankai that are not in the eyes of others reasonable, at least all people who see these things will think so.

For a five-kilometer track, it is necessary to get the front and carriages. Although the track transport trolley is easy to use, it is only a temporary device. Yes, but once it needs to be used for a long time, this kind of car is not suitable.

What the train wants in the end must be the front of the train, there is no doubt about this.

A good front can drive longer carriages, faster speeds, and greater capacity...Of course, this is also related to power, and then connected to electricity. For the shelter, I have to say that this is again A small stress project. At present, the main base of the shelter has three generators, which can provide more than enough electricity for the shelter. It's just that the pressure is a little bit heavy in this way, so An Kai thought about it and temporarily put the train's power supply at the transfer station.

At the main base, the three crews will not move temporarily, and it will not be too late to dismantle them when necessary.

Specific to the front model, the system provides many solutions, and Ankai needs to find the one that is most suitable for the current shelter.

The front model is directly marked with simple Ⅰ, Ⅱ, Ⅲ, and Ⅳ.

The Type I front should be the largest one. It is the vehicle with the largest width and the largest passenger capacity among all the fronts provided by the system. It is especially suitable for large cities with dense populations and large traffic. This locomotive is also divided into two sub-models, of which the A type is the third rail power supply, and the B type is the catenary power supply. The one-way transportation capacity of 6 vehicles can reach 50,000-70,000 person-times per hour, which is suitable for the transportation of large passenger flows in the urban area. The length of the line is about 30km.

For example, when Ankai travels through the city where he worked before, the subway should use a car head similar to this one, because it is a very large city with a population of over 10 million. As for his hometown, the first subway was built a year before he crossed, and he must have used a small car. After all, a small city with four tiers can build a subway. The city has developed rapidly in recent years, and the government has money to build it.

Type II locomotives, or Type II trains, are much smaller than Type I trains.

To be a digression, in fact, it is the front of the car, it is better to just say that it is the whole car. Because modern subway trains are different from earlier railway trains, the locomotives and carriages are manufactured at one time. The number of carriages and the suitable capacity for a locomotive are also calculated in advance. So it can be called a locomotive, and it can be called a complete train.

This one should be the most widely used subway model. Whether it is before or after crossing, according to the information learned by Ankai, it is commonly used in new subways in general cities. It is more suitable for urban rail transit systems with medium and large volumes. According to different flow receiving methods, it can also be divided into two models, A and B. One-way transportation capacity of 6 vehicles can reach 30,000-50,000 per hour.

Further down, there is train No. Ⅲ. This is the commonly referred to as the light rail model, which is rarely seen in subway lines and is suitable for urban rail transit systems with small and medium volumes. When 6 vehicles are assembled, the one-way capacity can reach 30,000 to 30,000 person-times per hour, and the capacity is also quite good. Of course, although this one is mainly an urban ground light rail adaptor, it is not impossible to use in the subway, but it is rare.

Further down is the No. IV model.

Mostly used for urban express lines.

That is, public transportation between the central city and the suburban new city or the airport.

It usually has the characteristics of relatively small passenger flow and long travel distance, which must be borne by express vehicles of higher speed class. The capacity load conditions are generally only considered in terms of standing 4 people m2, which is far lower than the standard of 6 people m2 standing in the city subway, so the total vehicle capacity will be greatly reduced compared to the city subway vehicles.

Further down, there are actually many other models, but I will not list them one by one.

And many of them do not meet the needs of the shelter at all.

For example, monorail trains, such as maglev trains, are very good, but they don’t fit well with the double rails built by Ankai, and they are useless.

The most common dual-track train is better.

As far as the capacity is concerned, there is no need to consider it, but for any serious train, the capacity will not be too bad. At the very least, it is much faster than ordinary cars.

Ankai finally chose train No. Ⅱ, which is the most common train, available in large cities and occasionally in small and medium-sized cities.

The front is flat and the body is square. The whole vehicle can be grouped in three gears of 4, 6, and 8, but the most common is a group of 6 cars. Each carriage is 19 meters long, 3 meters wide, and 4 meters high. The maximum speed can reach 120 kilometers per hour, but the shelter certainly does not need such an exaggerated speed. At present, there are only 5 kilometers of tracks. What do you do so fast~ www.novelhall.com~ In addition, the subway provided by the system has two different modes besides a single model.

One is the one-way mode and the other is the two-way mode.

The so-called two-way mode means that you can run before and after.

This situation is not seen in normal subways. Normal subways are the same as highways. If you go in one direction, you can only keep walking. If you want to return to the direction you were in, you can only go to the other subway station. Side, take another car. In fact, Ankai should have made a four-track two-way road, which is indeed more convenient for management and operation.

But he is going to be busy with one tunnel now, two tunnels, it can really be exhausted and paralyzed.

You can also build a large tunnel directly, which can accommodate two sets of tracks at the same time... But Ankai finally chose a single set of two-way driving mode. Anyway, he doesn't have to worry about the subway going back and colliding with the car coming up behind. His subway has only one car, so he can walk wherever he wants. One tunnel and one set of tracks are enough.

The train is selected and the model is put down.

The materials required for this train are also exaggerated, especially in the use of metal materials, which is currently the largest project second only to railroad tracks. And rails only need cast iron, but trains need more and more complex materials. In addition, he had to install the power grid in advance. The power transmission method includes separate rail power transmission and overhead power grid contact power transmission mode. Ankai chose the latter.

So he first took the transportation trolley and spread the power grid all the way from the main base to the transfer station. Then he returned to the main base and started to make trains.
