CONTENT Less pollution Low energy consume All-weather operation Faster More transport capacity More secure and comfortable 延时符 延时符 Faster than other ground transportation The top speed of the high-speed train can reach 350km/h, but the car only 120km/h,so this is a great saving of time.From the following picture, we can see that it takes only five hours if you take a high speed rail from Beijing to Shanghai, but the ordinary train takes nearly 20 hours. Faster than other ground transportation Although air transit moves at higher speeds than high-speed rail, total time to destination can be increased by check-in, baggage handling, security, and boarding, which may also increase cost to air travel, so HSR is best suited for journeys of 1 to 4 hours (about 150–900 km), for which the train can beat air and car trip time. 延时符 More transport capacity and less cost In China,the passenger capacity of the high speed rail can reach hundreds of millions of times, while the passenger volume of the aircraft is only a few million times.As we all known , China has the largest population, and most of us will choose trains as the main way of transportation, therefore this requires that our HSR must have a large capacity. More transport capacity and less cost An airplane spends significant amounts of time loading and unloading cargo and/or passengers as well as landing, taxiing and starting again. Trains spend only a few minutes stopping at intermediate stations, often greatly enhancing the business case at little cost. 延时符 More secure and comfortable With the continuous development of high-speed rail technology, its safety can be guaranteed . High-speed trains also have comfort advantages, since train passengers are allowed to move freely about the train at any point in the journey. But airlines have complicated
