1. The high-speed rail is designed and operated in a two-way split mode, that is, each high-speed rail line has trains running in two directions. This design ensures that passengers can travel from one place to another at any time without worrying about trains running in only one direction. Train dispatch and avoidance During the operation of the high-speed railway, if it is necessary to avoid other trains, the dispatch room will issue orders in advance. The driver will follow the instructions of the dispatch room and park the bullet train at the nearest platform and wait.
2. Since trains on bullet trains and high-speed trains can travel in both directions, there is usually no so-called "U-turn" problem. They can drive directly in the reverse after arriving at a station without any special U-turn operation. Comparison of traditional locomotive turning methods: For traditional vehicle-type trains, although most locomotives can also travel in both directions, in some cases, the locomotive may need to be taken off and replaced to the other side of the train to achieve specific operating requirements.

3. The operation mode of high-speed rail is two-way, and there is no one-way high-speed railway. If the high-speed rail needs to avoid other trains, the train can stop at the nearest platform and wait until the dispatch room issues a departure order, and the train can continue to travel. Therefore, when the high-speed rail needs to avoid other trains, the driver only needs to drive the high-speed rail in the other direction and can return the same way.
4. High-speed rail does have regulations that flight attendants must turn chairs themselves. EMU trains have the ability to travel in both directions, which means they can travel in the opposite direction by changing the cab without changing the direction of the head. In order to ensure that passengers have the best riding experience during the train, the high-speed railway stipulates that flight attendants need to manually turn the seat direction when the train returns to keep it consistent with the train's running direction.
5. Double track is two tracks. Running in both directions. It's just that high-speed trains run by electricity, so there are high-voltage poles on both sides of the track of high-speed trains and high-voltage lines are suspended above them. High-speed trains and high-voltage trains are in contact with the high-voltage lines through contact devices on the roof of the trains. The catenary is a special form of transmission line erected above the railway line to supply power to electric locomotives. It consists of contact suspension, support device, positioning device, pillar and foundation.

1. Compensation for traffic accidents. If you are hospitalized or require nursing care, the insurance company will compensate for the lost time and nursing expenses. For those who are not hospitalized, if the doctor issues a certificate of recuperation at home, they will also have to compensate for the loss of work, but the nursing fee will not be compensated. For those who recuperate at home, it means that they can live and take care of themselves. For those who can take care of themselves, they cannot compensate for the nursing fee.

3. Legal analysis: If compensation will be paid, lost work expenses and nutrition expenses are included in both compulsory transportation insurance and third-party liability insurance, but insurance companies adhere to the principle of "necessary and reasonable" in the reimbursement of these expenses. That is, if the insurance company believes that a certain part of these expenses is unreasonable or unnecessary, it will deduct this part of the expenses, such as nutrition expenses. Insurance companies understand it this way: medical drugs that must and are reasonable to restore the victim's health.
4. The compensation for lost work and nursing expenses after the traffic accident injured are discharged from the hospital will mainly be paid by the insurance company, but the part exceeding the limit must be shared by the party concerned in accordance with the civil compensation proportion.

Specifically, these two expenses will be compensated within the death and disability compensation limit of 110000 yuan for compulsory insurance.
