In recent days, a long period of freezing rain has suddenly fallen in the city of WuhanTransportationMobility has had a big impact. First of all, freezing rain caused the failure of the train's power supply system. Due to the icing effect of freezing rain, the power supply lines are covered with ice and cannot transmit power properly, resulting in train stoppages or delays. Although it is possible to achieve limited operation by forcibly driving, this will bring great wear and tear to the equipment and there is a certain safety risk. Although the Wuhan Railway has tried its best to deal with it, it is difficult to find a solution in the face of the challenge of extreme weather for the time being. Secondly, freezing rain also caused Wuhan Tianhe AirportFlight delays。Cleaning an airport runway is relatively straightforward compared to the complexity of cleaning up the train's power supply system. As long as the runway is kept clean, the aircraft can take off and land normally. However, due to the constant freezing rain, crews need to periodically carry out runway clearances, which can lead to:Flight delayshappens.
Unlike the train,aviationIt can play to its advantage in the face of extreme weather or extreme conditions. For example, in freezing rain, although the movement of trains passing through Hubei may be affected, the planes flying over Wuhan will not be affected in any way. aviationThe advantage lies in flexible routing and the ability to cross obstacles. In the event of an extreme situation where an airport runway is damaged or destroyed, repairing a runway that is available for take-off and landing is not difficult and can be dealt with in just a few hours. In addition, the aircraft can take off and land on airstrips and highways, with the flexibility to adjust the route at any timeRail systemUnable to do this. Therefore, in extreme weather or extreme conditions,aviationTransportationIt has become the choice of the bottom.
Although high-speed rail in civilian useTransportationThe field has its advantages, but inMilitaryHowever, there are certain limitations in terms of field and freight. High-speed rail is in the faceMilitaryThere is no special value when it is threatened. One pieceMissilesThe blow is enough to completely paralyze a high-speed railway, and the repair can take days or even months to complete. If it is a tunnel that is damaged, the entire line may have to be scrapped. In comparison, even by ten piecesMissilesThe runway can still be repaired. Restoring a runway that can be used by planes for take-off and landing is not complicated and only takes a few hours of work. In addition, the aircraft can take off and land on airstrips and highways, and has the ability to flexibly change routes, which is anyRail systemNone of them can be achieved. In addition, high-speed rail has its limitations when it comes to freight. Due to the limited carrying capacity of high-speed rail, materials exceeding 110 tons need to be transported by ordinary railway. As a result, high-speed rail is only suitable for transporting passengers quickly and does not have a particularly high value for freight.
aviationTransportationInMilitaryEconomywithStrategic thinkingplays an important role. In the face of the current complex and changeable world situation, the defense of the world needs to rely on the input of ships and aircraft. aviationIt is offensive, and the high-speed rail is just the object of the beating. ModernInternationalConflicts are mostly based on long-range strikes, and it is difficult to imagine that other countries have the ability to attack directlyHomeland。Therefore, we want to leave the enemy outside the country and rely on ships and aircraft for defense and attack. Comparatively speaking, the obsession with high-speed rail is just a manifestation of conservatism and lack of self-confidence, lacking a sense of strategy andEconomyThinking deeply. fromEconomyFrom perspective, building high-speed rail is much more expensive than building an airport. Enough money to build a 400-kilometer high-speed railway, enough for every county in a province to have a regional airport. Therefore, on the premise of satisfying the high-speed rail connectivity of major cities and important cities, we should also pay more attentionaviationTransportationdevelopment. In the next twenty years,aviationIt is quite possible to become fastTransportationof the mainstream.
Freezing rain caused train stoppages and delaysaviationThanks to the ease of flexible route and runway maintenance, it is possible to maintain relatively stable operation in some extreme situations. In addition, this article also ** high-speed rail inMilitaryand the limitations of freight, as well as the importance of air traffic in military, economic, and strategic thinking.
