There are foreign objects hanging on the Beijing-Shanghai high-speed rail contact network. What is the impact of some trains running late?

There are foreign objects hanging on the Beijing-Shanghai high-speed rail contact network, and some trains are delayed due to the windy weather.

Railway transportation and safety are closely related to the national economy and people's livelihood, and sometimes they are limited by human efficiency. Whether it's security or ... Accident? Processing takes a long time.

What happened: On the afternoon of April 29th, around 1, many passengers who took the train at Beijing South Railway Station found that some high-speed trains were late.

The train was originally scheduled to leave at 1: 05 pm. It's more than 45 minutes late now, and there's still no notice of the departure time. The G23 train is five minutes earlier than the train and is still waiting at Beijing South Railway Station. ? A passenger on the high-speed rail G 135 said.

It turned out that due to the strong wind, the Beijing-Shanghai high-speed railway hung a foreign object on the contact network between Tianjin South and Cangzhou, Qingxian County, Cangzhou City, Henan Province, causing some trains to be delayed. The railway department immediately disposed of this. After 35 minutes, the foreign objects hanging on the hanging net have been removed, and the train order has gradually recovered. In the afternoon 1: 42, the delayed train gradually resumed.

Popular science:

How can a high-speed train determine that there are no foreign objects on the track ahead, or that the track has been damaged and passed the sensor? When there is no train passing on the railway track, there is current, and when there is a problem somewhere on the track, the current will be automatically interrupted. Then there will be a problem with the track in the monitoring room, and then someone will be sent to repair it quickly. The car body has its own obstacle sweeper, and the foreign objects on the track will be removed directly.

We are also very curious about this, how to clean up the foreign objects hanging on the net? The overhead foreign body remote cleaning equipment of catenary is to use powerful directional laser beam to quickly remove suspended foreign bodies. What do railway people call it? Laser cannon? . In order to ensure the stability of high-speed rail power supply lines, Zhengzhou high-speed rail infrastructure section is equipped with? Laser cannon? , and formulated the use and operation procedures. And trained relevant personnel. At the same time, this section continuously collects kites and light objects hanging on the catenary by means of foot patrol, boarding inspection and 4C equipment inspection. And find out by sending relevant information through the nail office system? Prey? And use it in the fastest time? Laser cannon? Eliminating hidden dangers, it won't take long for the laser gun to quickly remove foreign objects hanging on the catenary, which has the advantages of quickness, high efficiency and electrification.

Conclusion: It is not uncommon for foreign objects to appear on the high-speed rail network, but it is rare for high-speed rail to be delayed, because generally speaking, high-speed rail is very efficient and punctual, and there are foreign objects when it is delayed, which is also a necessary measure taken by the high-speed rail department in China for the personal safety of passengers.
