What are the safety hazards of train travel?

Abstract: Trains have become the first choice for most ordinary people to go out. Safety, comfort and punctuality are the reasons why many people choose to travel by train. However, passengers should pay attention to the fact that although the train has developed for a long time, it also has certain security risks, which may easily lead to railway safety accidents. Understand these safety hazards and learn the common sense of train safety in order to nip in the bud. First, the safety hazards of train travel

1, improper scheduling

Improper dispatching is the most common factor that causes railway accidents in the early stage, and it is easy to cause the following car to break into the driving area of the preceding car prematurely, which is related to most rear-end collisions and train collisions. 20 1 1 yongwen line 7.23 the direct cause of the particularly serious railway traffic accident is the chaotic dispatching. With the rapid development of electronic information and communication technology, the railway dispatching system is not what it used to be, and the possibility of major railway accidents caused by train dispatching errors of EMU on newly-built high-speed (including high-speed) railway lines is greatly reduced.

2. speeding in corners

Trains are fast and heavy, and turning requires a strong centripetal force. If speeding, the horizontal component of the train's gravity will not provide enough centripetal force for the train, and the train will squeeze the outer rail, causing derailment accidents. The derailment accident of JR Fukuyama Line in Hyogo Prefecture, Japan on April 25th, 2005, and the derailment accident of Spanish train on July 24th, 20 13, were all caused by the speeding of the train on the curve. At present, China's Ministry of Railways requires operating trains to run at a reduced speed, which is obviously lower than the speed design standard for preventing speeding accidents.

3. Geological disasters

Traditional railways mostly cross mountains and rivers, which are sparsely populated and dangerous, and are hotbeds of geological disasters. Once the bridge collapses and the tunnel collapses due to natural disasters, the train will easily derail, be buried or fall off the cliff. 198 1 The rear-end collision of chengdu-kunming railway bullet trains was caused by a debris flow in a ditch, a tributary of the Dadu River, which washed away the railway bridge. With the maturity of bridge and tunnel engineering technology and satellite monitoring technology, such accidents have been effectively curbed.

4. Equipment failure

The mass of the train is large, even if the speed is tens of kilometers per hour, the inertia is large and the braking distance is long. If the railway system equipment fails, it will easily lead to chaos in dispatching, which will eventually lead to the driver's failure to confirm the road ahead, leading to rear-end collision or collision. The 4. 1 1 passenger train rear-end collision on Beijing-Kowloon Railway in 2006 was a tragedy caused by the driver's misjudgment due to the failure of the signal lamp. The cause of Wenzhou bullet train accident is also the failure of signal light equipment. High-speed rail system is more dependent on equipment, so reducing the failure rate of equipment and adding more reliable emergency equipment is one of the important links in high-speed rail construction.

5, parts aging

High-speed trains, like civil aircraft, may roll over once some components are loose, deformed or fall off. The high-speed rail accident in Ashdod 1998, Germany, was the derailment of the train, because the wheel shell was deformed, fell off the rail and got stuck in the railway fork. High-speed train and its high-speed track are equipment with a large number of complex and precise parts, and the operating environment is extremely harsh, which increases the difficulty of locomotive and vehicle maintenance and railway track maintenance.

6. Illegal buildings

Illegal construction by railway maintenance personnel is a common reason why trains hit pedestrians, such as the major cross-country traffic accident on Ji Jiao Line 1.23 in 2008. At present, the protective measures along the railway are relatively perfect, and viaducts are used in large areas to prevent pedestrians from breaking into the track to some extent.

7. Illegal operation

Illegal operation is the most fundamental cause of railway accidents at this stage. Including the above examples, are basically closely related to illegal operations. Nowadays, science and technology are very developed, and a series of railway safety protection systems are often multi-layered. If the rules and procedures are strictly followed, even the failure of a certain link can be found and corrected in time.

Second, the train safety knowledge

1. Choose the regular ticket purchasing channels: 12306 online booking, 95105 telephone booking, train station or sales point window booking, and station ticket vending machine booking.

2. At present, train tickets are registered in real-name registration system. Don't trust online ticket transfer information to prevent being cheated, and don't use other people's ID card information to buy train tickets from others. When the person, ticket and certificate do not match, it will be impossible to enter the station and the ticket will be invalid.

3, don't go out too scattered luggage, it is best to concentrate luggage, common items on the road (such as food) and valuables are stored separately to prevent loss.

4. When entering the station for security check, you should see that the luggage enters the entrance of the security check machine and then get it at the exit to prevent criminals from fishing in troubled waters and stealing property from the conveyor belt.

It's crowded to get in and out of the station and get on and off the bus. Be careful with wallets and valuables. If the backpack is not too big, it's best to hang it on your chest. Don't put your wallet in the outer pocket of clothes that are vulnerable to thieves.

6. When taking a hard seat, try to put your luggage on the luggage rack beside the seat after getting on the bus, instead of directly on it, so that your luggage can be easily observed.

7. Don't look at your valuables all the time, let people see that there is no money in this place, and don't carry or let others see a lot of cash. Prepare the change in advance so that the money will not be exposed.

8. it is essential to prevent people. Some lawless elements use the excuses of "fellow villagers" and "peers" to strike up a conversation or give away food, drinks and cigarettes. As soon as you relax your vigilance, you will commit fraud and theft. Be careful not to eat strangers' food.

9. Don't lend your mobile phone to others easily, or show it to others. Now there are many bad guys pretending to borrow or appreciate, remember your contact number and wait for the machine to commit fraud or theft.

10, take a hard seat and take care of valuables when dozing off. When taking the sleeper, put valuables beside you before going to bed. The window of the green van can be opened. You should obey the conductor's arrangement and be careful not to put important items on the tea table by the window when you sleep.

1 1. Pay attention to people who turn over their luggage, and pay attention to the safety of luggage when the train stops to get on and off passengers.

12. When you leave the station, don't talk to others easily. Take the bus, subway or taxi at the designated place of the station, find a regular hotel or hotel to stay in, and don't trust the people soliciting customers at the exit.

13. If you have any difficulties on the train, please ask the train attendant for help.
