For some questions about the D7802 bullet train of Wuhan Guangzhou high speed railway, a reward of 2

How long does D7802 stop at Leiyang West Station?

Stop for six minutes. How many carriages are toilets and dining cars arranged at the mouth?

The toilet is generally at the back of the carriage, and the dining car is generally at the 5th and 13thNo. car.

You are 6 cars, can you go to 9 cars?

The answer is yes, you can move around freely inside the train.

What is the difference between Wuhan-Guangzhou high-speed rail bullet train and high-speed rail? Why are bullet trains so much cheaper?

Because on the rails where the bullet train runs, there are other types of trains running, such as trains that start with K, Z, and T. It belongs to the first line of multiple vehicles. So it's cheaper.

On the rails of the high-speed railway, only the trains starting with the G are running, and there are no other trains running. It belongs to the special line and special car. So it's more expensive.

Is there a lot of people in this car in general? Is it noisy in the car? (Carriage 6) EMUs are generally taken by high-quality people such as business people or entrepreneurs, so it should not be too noisy.

What is the CRH model number of the D7802? What is the maximum speed?

CRH380B, top speed 400 km/h.

Which stopovers are there along the way? Stop for a few minutes?

See diagram below. <>

1.CRH3C, the maximum speed is also 300, but there are more to be avoided, and the speed is slightly slower.

2.11:07 arrived, 13 opened, stopped for 6 minutes, should be to avoid a high-speed train.

3.Toilets are available in every car, and food trucks are available in 4 cars.

53 --5.The attendance rate is very high, and the noisy situation depends on whether there are bear children.

6.CRH3C is reconnected, and 6 cars and 9 cars are not connected.

7.The difference lies in the operation arrangement, the EMU stops more, waits to avoid more, and the speed is slightly slower; The high-speed rail has fewer stops, fewer avoidances, and a slightly faster speed. **The difference is due to different tiers and different pricing scales.

Each railway station has ticket vending machines that sell tickets for the Wuhan-Guangzhou high-speed railway.

The station where Shenzhen takes the Harmony to Guangzhou and gets off is called Guangzhou East Railway Station, and there are also automatic ticket machines.

Now that the Spring Festival is at its peak, the Wuhan-Guangzhou high-speed rail ticket before the Spring Festival has long been gone.

You take the bus on the 10th, so don't you book a ticket early. Not to mention the ticket of the day, you can get on the bus on the Chinese New Year's Eve is already thankful.

There are ticket vending machines in Guangzhou East, Guangzhou North, and Guangzhou South.

Tickets for high-speed rail can be bought at various ticket sales agencies in Guangdong Province, so why bother to buy them at the automatic ticket vending machines.

Shenzhen can take the harmony to Guangzhou East Railway Station and Guangzhou Station, it is recommended to sit to Guangzhou Station, and then to Guangzhou Bus Terminal to Guangzhou South Railway Station to take the special bus, to the South Railway Station and then to the automatic ticket machine to buy tickets, if you want to take the high-speed rail in Shenzhen, it is not recommended to take the Harmony to go, take the car to Guangzhou South Railway Station will be faster.

Now the automatic ticket machine has no high-speed rail tickets, all of them have been bought by scalpers, if you don't buy a ticket to Guangzhou South Railway Station to buy a ticket, it is estimated that you can't buy it.

Guangzhou Railway issued an announcement that it would open an additional bus to see if you are so lucky.

Wuguang should be Guangzhou South Railway Station If you want to go to the train station to buy a ticket, it's best to book it Now the ticket is very tight.

Guangzhou can be booked, I can play in Shenzhen, I can buy **, and then go to a ticket office to get a ticket, this does not need a real name, and it can be booked 20 days in advance.

Ticket vending machines are available, but if you want to buy the same day, it depends on your luck. Most of the time you can't buy it.

I went to Guangzhou North to buy, I can buy the same day, I am like this.

The high-speed EMUs operating in the previous stage of the Wuhan-Guangzhou high-speed railway were mainly CRH2 and CRH3 models. Among them, the specific model of CRH2 is its 300 km grade second stage car, the motor power is increased, and the traction performance is enhanced. Recently, it seems that CRH380A, CRH380AL and CRH380BL have also begun to deploy the Wuhan-Guangzhou high-speed railway.

The reconnected cars are generally 8-group short cars, the CRH2 and CRH3 of the Wuhan-Guangzhou high-speed railway are both short cars, and the long trains are 16-grouped, which do not need to be reconnected, of course, they cannot be reconnected. The first 40 columns of CRH380A are short knitted, and the 40 columns behind are long CRH380AL, and CRH380BL are all long knitted cars.

The D prefix is an EMU, not a high-speed EMU.

High-speed EMUs are G-prefixed.

It's high-speed rail!

N° D7802 Running time 3h 51min Guangzhou South - Changsha South (Day 1 arrival).

Departure Station: Guangzhou South, Terminal: Changsha South, Hard Seat: 220, Soft Seat: 350, Departure Time: 08:33, Arrival Time: 12:24, Hard Sleeper, Upper Middle, Lower 0 0 0

Type EMU The total distance is 707 km.

Chenzhou West Railway Station is a high-speed rail station, and the D in D7802 is the 'D' shaped locomotive. High-speed locomotives are mostly of this shape.

The D prefix is the bullet train, take the train at the high-speed rail station. It's about the same speed as the high-speed rail, just a few more stops. I do it often.

By optimizing the aerodynamic performance of the EMU to achieve the technical requirements, the EMU shape is further smoothed designed, the external windshield is added, and the aerodynamic shape of the car body such as the pantograph shuffle cover and the air conditioning shroud is optimized to achieve the goal of reducing air resistance 5 so that the EMU does not derail.

The Wuhan-Guangzhou high-speed EMU has made a bold attempt to optimize the relationship between wheels and rails so that it has sufficient safety margin during high-speed operation. The ground-mounted wireless block center system can make the brain of the high-speed EMU more flexible.

Domestic high-speed EMUs are in the leading position in the world in terms of traction system and braking system. A high-speed train with a speed of 350 kilometers per hour needs to slow down and slide kilometers if it brakes instantaneously. China's self-developed "train control" technology has a high degree of intelligence, in case of emergency, through the ground main control room signal command, the EMU can ensure a safe stop within 5 kilometers.

The take-off speed of a Boeing aircraft is about 220 kilometers per hour, and the speed of a train reaches 350 kilometers per hour. According to some data, when a train with a speed of 200 kilometers per hour passes, the wind speed on both sides of the railway is equivalent to a strong wind of 7 or more.

Especially when two vehicles meet and pass through tunnels, the piston effect generated by the vehicle causes large pressure fluctuations in the vehicle body, which seriously affects stability, comfort and noise.

To solve this problem, the optimization of the aerodynamic performance of the EMU is mainly adopted to achieve the technical requirements, the shape of the EMU is further smoothed, the external windshield is increased, and the aerodynamic shape of the car body such as the pantograph shroud and the air conditioning shroud is optimized to achieve the goal of reducing air resistance 5.

The line of the high-speed rail is very straight and straight, and due to the action of gravity, the wheels are stuck on the two rails, and naturally they will not derail. And the straightness of the rail is calculated in millimeters, which is very accurate. Again, the detection and monitoring system of high-speed rail is also relatively perfect, which can ensure that it does not derail at high speeds.

The previous phase of the Wuhan-Guangzhou high-speed railway operated high-speed EMUs were CRH2 and CRH3 models. Among them, the specific model of CRH2 is a 300-kilometer two-stage car, the motor power is increased, and the traction performance has been improved. Recently, it seems that the Wuhan-Guangzhou high-speed rail running CRH380BL CRH380A CRH380AL began deployment.

The car reconnected is an 8-car group of short **, the Wuhan-Guangzhou high-speed railway running CRH2, CRH3 short compilation car long series sedan has 16 subclasses, no reconnection, of course, can not be reconnected. The CRH380A 40 is a short series, after the 40 long plans the CRH380AL CRH380BL programmed car commander.

The difference with high-speed rail is that the railroad has to be resurfaced, and you have to take the approach straight, and you have to weld the rails.

Not unless it happens!

Since it is outside, it cannot be prevented!

There must be more people than usual at the Spring Festival station, 20 minutes is still very tight, and you can barely catch up by running all the way, but in case there is any emergency, it is difficult to catch up.

Yes, you can get the transfer card at Xiaolan Station first, and you don't need to leave the station after arriving at the South Railway Station, you can go directly to the waiting area of the Wuhan-Guangzhou high-speed railway.

Basically, it won't be delayed, as it's the highest grade train on this line.

However, no one can say for sure.

For the time being, I haven't encountered an inaccurate point, and the error is within 5 minutes (I encountered).
