There are questions about multiple trains on the same train

Definition of trains: from Beijing to other parts of the country or from the trunk line to the branch line is downward, the number of trains is an odd number, otherwise it is an even number. So there are two general train trips, i.e., up and down.

But if you think about it, what if there was a train running from one trunk line A to another trunk line B via a branch line AB? Should its trains be odd or even, that is, up or down? There is a paradox that creates a paradox.

Usually the railway department's solution is to define a station C in the middle of the branch line AB between two main lines as the train change location. That is, the AC segment is a downlink odd number, and the CB segment is an uplink even number.

The problem is not that simple, because if it were just that, it would only take two trips, not four. So why four trains?

If you use only two trains, it is possible to have two trains with the same number but in completely different directions at the same station!! If you think about it, isn't that so?? If this happens, it will not only cause inconvenience to passengers, but more seriously, it may bring confusion and confusion to the dispatching and transportation of the station!

If you get it wrong, the consequences are unimaginable!

For the sake of simplicity and clarity, we take the k237 8 9 0 from Taiyuan to Guangzhou East on the 2nd floor to illustrate: assuming that there are only two numbers and no 239 240, Huashan to Luohe is not 240 but 238, and Guangzhou to Luohe is also 238, so there may be two trips to 238 in Luohe! But the direction is from Guangzhou and Huashan, and the direction is completely opposite!

For the sake of safety, just in case, the railway department had to define the number of trains from Huashan to Luohe as 240 (of course, it can also be 236) to distinguish them. In this way, there is a phenomenon that there are four trains in the train.

The problem of train numbers is very easy to understand, let me say a general meaning, all the trains in the country to Beijing direction are double number, if you change directions halfway, become far away from the direction of Beijing, you need to become a single number. For example, the train from Shanghai to the Northeast is a double number before passing Beijing, and the train number will be changed to a single number after Beijing and continuing to the Northeast.

The number of trains is not without rules to follow, even if it is changed to other trains, they are generally next to each other, and there will be no difference of 108,000 miles.

In the case of the same train, there are two Tachibana trains, which is determined by the train numbering rules.

The railway stipulates that the national train to Beijing is the upward number, and the train number is an even number, while the back Beijing direction is downward, and the train number is an odd number. For example, the special express train from Beijing to Shanghai is T109, and from Shanghai to Beijing is T110.

If it is in other directions, such as Shanghai to Urumqi, the section from Shanghai to Xuzhou is up, and the train number is Liang Z40, and after arriving in Xuzhou, it becomes the back to Beijing, so the train number becomes Z41, which is actually the same train.

<> there is nothing inconvenient for passengers to change the number of trains. But for the person who picks up the station, if you don't understand this, it may bring some small confusion to the pick-up station. For example, you tell a friend in Urumqi that the train you took is Z40, but the person who picks up the station can't find this train in Urumqi.

The number of trains is inferior to the single and double numbers of the word number and the mantissa number.

With Beijing as the center, the train departing from Beijing is a single number, and the train heading for Beijing is a double number.

Most of the trains do not pass through Beijing, it depends on whether the running line is from Beijing or to Beijing, and some of the trains have changed their direction after passing through the hub station, and the train number has changed (trembling and must be single to double, or double to single).

In order to standardize the order of railway transportation, reasonably arrange the railway train schedule, facilitate the transportation dispatching and command units at all levels of the railway, and command and monitor the railway operation in real time to ensure the safety and order of the railway operation and distinguish the direction of train operation, the competent railway department has specified the direction of the trains running on the national railway.

All railway trains are in the direction of approaching Beijing (entering or approaching) as the upward direction, and the number of trains is numbered as an even number; Railway trains are all in the direction away from Beijing (out or away) as the downward direction, and the number of trains is numbered as an odd number. For example:

Taiyuan opened Shanghai direct express train Z98 5 times, in Taiyuan Shijiazhuang north is Z98 times, Shijiazhuang north to Shanghai is Z95 times.

Shenyang north to Taiyuan bullet train D194 1 times, Shenyang north to Beijing west D194 times, Beijing west to Taiyuan between D191 times.

The direct express Z96 7 cars from Shanghai to Taiyuan are Z96 times between Shanghai Shijiazhuang North and 97 times between Shijiazhuang North Taiyuan.

In the course of the train, it changes from up to down or from down to up, and several defining policies for changing the number of trains:

1. The train is centered on Beijing, the train departing from Beijing is downward, and the train heading for Beijing is upward.

2. On the main railway line connecting Beijing to Beijing, it is upward and downward.

3. If the railway is not connected to Beijing or is a branch line, then the direction of the trunk line towards Beijing is the upward direction, and the direction of the main line away from Beijing is the downward direction.

4. On the same railway line, from the station near the starting point of the line to the station near the end of the line, it is the next jujube stupid line, and vice versa.

5. According to the technical management regulations of the Ministry of Railways, the running direction of the train shall be subject to the regulations of the Ministry of Railways, but the running direction of the train in the hub area shall be stipulated by the railway bureaus, that is, the upward and downward directions can be artificially specified.

Hello, there are multiple trains on the same train, usually caused by imitation of the following reasons: 1Different Departure Stations:

The same train will have different vehicle types, routes and stops when transporting across regions, and different train number signs need to be set up; There may also be administrative reasons such as statistics or billing. 2.Train Change:

Some long-distance trains do not arrive at the terminal station all at once, but pass through several stations in the middle and need to be transferred. When a train travels from one station to another, in order to facilitate passengers to take the train and arrange the travel plan of the train, the train will use different train numbers to indicate different train segments, and sell corresponding tickets separately. 3.

Random addition: In some cases, station staff may randomly generate train numbers based on the system algorithm when setting up the ticketing system, so that the system can record and distinguish when the data is processed. In general, there are multiple different train numbers on the same train, mainly for the purpose of statistical transportation data, convenient passenger ticket purchase, convenient management, and improve the efficiency of the transportation industry.

Summary. There are several reasons why there will be multiple trains on the same train:1

Different origins and destinations: The same train may run between different origins and destinations, which can lead to multiple trains. For example, a train from Beijing to Shanghai may have multiple <> such as G1, G3, G5, etc

2.Different stops: The same train may pass through multiple stops along the way, and different trains may stop at different stops. This caters to the needs of different passengers and makes it easier for them to get on and off at different stops. <>

3.Different carriage configurations: The same train may have different carriage configurations, such as hard seats, soft seats, hard sleepers, soft sleepers, etc. Different trains may have different types of seats and berths to meet the different needs of passengers. <>

4.Different running times and speeds: The same train may run at different times and may travel at different speeds. In this way, there will be different trains to meet the needs of passengers traveling at different times. <>

5.Different service classes: Different service classes may be provided for the same train, such as premium EMUs, ordinary EMUs, etc. Different trains may offer different standards of service and facilities to meet the different needs of passengers. <>

Why do there be multiple trips on the same train?

Hello, there will be multiple trains on the same train to meet the different needs of passengers, including different start and end points, stops, carriage configurations, running times and speeds, and service levels. This provides more flexibility and a variety of stool options, allowing passengers to travel according to their needs. <>
